New function is not currently called but will be called in upcoming commits. It
moves database path checking, and existence checking, and already-loaded
checking, and verification into a single function so this logic does not need
to be repeated all over higher level wallet code, and so higher level code does
not need to change when SQLite support is added in
https://github.com/bitcoin/bitcoin/pull/19077. This also lets higher level
wallet code make fewer assumptions about the contents of wallet directories.
This commit just adds the new function and does not change behavior in any way.
This removes a source of complexity and indirection that makes it harder to
understand path checking code. Path checks will be simplified in upcoming
commits.
There is no change in behavior in this commit other than a slightly more
descriptive error message in `loadwallet` if the default "" wallet can't be
found. (The error message is improved more in upcoming commit "wallet: Remove
path checking code from loadwallet RPC".)
752e6ad533 Protect localhost and block-relay-only peers from eviction (Suhas Daftuar)
Pull request description:
Onion peers are disadvantaged under our eviction criteria, so prevent eventual
eviction of them in the presence of contention for inbound slots by reserving
some slots for localhost peers (sorted by longest uptime).
Block-relay-only connections exist as a protection against eclipse attacks, by
creating a path for block propagation that may be unknown to adversaries.
Protect against inbound peer connection slot attacks from disconnecting such
peers by attempting to protect up to 8 peers that are not relaying transactions
but have provided us with blocks.
Thanks to gmaxwell for suggesting these strategies.

0bbe26a1af wallet: filter for keys only before record deser in salvage (Andrew Chow)
544e12a4e8 walletdb: Add KeyFilterFn to ReadKeyValue (Andrew Chow)
Pull request description:
When salvaging a wallet, the only things that matter are the private keys. It is not necessary to attempt to deserialize any other records, especially if those records are corrupted too.
This PR adds a `KeyFilterFn` function callback to `ReadKeyValue` that salvage uses to filter for only the records that it wants. Of course doing it this way also lets us do other filters in the future from other places should we so desire.

Previously we deduced it was a block-relay-only based on presence of the
m_tx_relay structure. Now we have the ability to identify it directly via a
connection type accessor function.
We previously identified if we relay addresses to the connection by checking
for the existence of the m_addr_known data structure. With this commit, we
answer this question based on the connection type.

c276df7759 zmq: enable tcp keepalive (mruddy)
Pull request description:
This addresses https://github.com/bitcoin/bitcoin/issues/12754.
These changes enable node operators to address the silent dropping (by network middle boxes) of long-lived low-activity ZMQ TCP connections via further operating system level TCP keepalive configuration. For example, ZMQ sockets that publish block hashes can be affected in this way due to the length of time it sometimes takes between finding blocks (e.g.- sometimes more than an hour).
Prior to this patch, operating system level TCP keepalive configurations would not take effect since the SO_KEEPALIVE option was not enabled on the underlying socket.
There are additional ZMQ socket options related to TCP keepalive that can be set. However, I decided not to implement those options in this changeset because doing so would require adding additional bitcoin node configuration options, and would not yield a better outcome. I preferred a small, easily reviewable patch that doesn't add a bunch of new config options, with the tradeoff that the fine tuning would have to be done via well-documented operating system specific configurations.
I tested this patch by running a node with:
`./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=tcp://127.0.0.1:28332 &`
and connecting to it with:
`python3 ./contrib/zmq/zmq_sub.py`
Without these changes, `ss -panto | grep 28332 | grep ESTAB | grep bitcoin` will report no keepalive timer information. With these changes, the output from the prior command will show keepalive timer information consistent with the configuration at the time of connection establishment, e.g.-: `timer:(keepalive,119min,0)`.
I also tested with a non-TCP transport and did not witness any adverse effects:
`./src/qt/bitcoin-qt -regtest -txindex -datadir=/tmp/node -zmqpubhashblock=ipc:///tmp/bitcoin.block &`

Enable the GUI to also use the load_on_startup feature.
Wallets loaded in the GUI always have load_on_startup=true.
When they are unloaded from the GUI, load_on_startup=false.
To facilitate this change, UpdateWalletSetting is moved into the wallet
module and called from within LoadWallet, RemoveWallet, and
Createwallet. This change does not actually touch the GUI code but
rather the wallet functions that are shared between the GUI and RPC.

On the way of transit from `RecursiveMutex` to `Mutex` (see #19303) it is crucial to have run-time `AssertLockHeld()` assertion that does _not_ hide compile-time Clang Thread Safety Analysis warnings.

fa93bc14c7 rpc: Remove unused return type from appendCommand (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in misc. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

6d1f51343c [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)
Pull request description:
When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.
Note that when creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.
See #7518 for historical background.

This fixes both issues by defining it and checking its value instead of whether it is merely defined.

ca185cf5a1 doc: Document differences in bitcoind and bitcoin-qt locale handling (practicalswift)
Pull request description:
Document differences in `bitcoind` and `bitcoin-qt` locale handling.
Since this seems to be the root cause to the locale dependency issues we've seen over the years I thought it was worth documenting :)
Note that 1.) `QLocale` (used by Qt), 2.) C locale (used by locale-sensitive C standard library functions/POSIX functions and some parts of the C++ standard library such as `std::to_string`) and 3.) C++ locale (used by the C++ input/output library) are three separate things. This comment is about the perhaps surprising interference with the C locale (2) that takes place as part of the Qt initialization.

7cd4159ac8 [net processing] Add Peer (John Newbery)
aba03359a6 [net processing] Remove CNodeState.name (John Newbery)
Pull request description:
We currently have two structures for per-peer data:
- `CNode` in net, which should just contain connection layer data (eg socket, send/recv buffers, etc), but currently also contains some application layer data (eg tx/block inventory).
- `CNodeState` in net processing, which contains p2p application layer data, but requires cs_main to be locked for access.
This PR adds a third struct `Peer`, which is for p2p application layer data, and doesn't require cs_main. Eventually all application layer data from `CNode` should be moved to `Peer`, and any data that doesn't strictly require cs_main should be moved from `CNodeState` to `Peer` (probably all of `CNodeState` eventually).
`Peer` objects are stored as shared pointers in a net processing global map `g_peer_map`, which is protected by `g_peer_mutex`. To use a `Peer` object, `g_peer_mutex` is locked, a copy of the shared pointer is taken, and the lock is released. Individual members of `Peer` are protected by different mutexes that guard related data. The lifetime of the `Peer` object is managed by the shared_ptr refcount.
This PR adds the `Peer` object and moves the misbehaving data from `CNodeState` to `Peer`. This allows us to immediately remove 15 `LOCK(cs_main)` instances.

Pull request description:
The change removes an old check for IPv6 addresses in range ::ff:ff00:0:0:0/72 that were created due to a bug in size field of addr messages for 0.2.8 nodes and before.
This check is no longer needed as they are no more pre 0.2.9 nodes on the network (as per bitnodes network snapshot).

d3e8adfada util: remove c-string interfaces for DecodeBase58{Check} (Sebastian Falbesoner)
Pull request description:
This micro-PR gets rid of base58 function interfaces that are redundant in terms of c-string / std::string variants; the c-string interface for `DecodeBase58Check` is completely unused outside the base58 module, while the c-string interface for `DecodeBase58` is only used in unit tests, where an implicit conversion to std::string is not problematic.

Add WalletClient interface so node interface is cleaner and don't need
wallet-specific methods.
The new NodeContext::wallet_client pointer will also be needed to eliminate
global wallet variables like ::vpwallets, because createWallet(), loadWallet(),
getWallets(), etc methods called by the GUI need a way to get a reference to
the list of open wallets if it is no longer a global variable.
Also tweaks splash screen registration for load wallet events to be delayed
until after wallet client is created.
Add AppInitInterfaces function so wallet chain and chain client interfaces are
created earlier during initialization. This is needed in the next commit to
allow the gui splash screen to be able to register for wallet events through a
dedicated WalletClient interface instead managing wallets indirectly through
the Node interface. This only works if the wallet client interface is created
before the splash screen needs to use it.
a99a3c0bd6 rpc: Validate provided keys for query_options parameter in listunspent (pasta)
Pull request description:
At Dash, one of our developers was working with the `listunspent` RPC command, but instead of saying "minimumAmount" he said "minimmumAmount" as such the RPC wasn't working as expected.
In https://github.com/dashpay/dash/pull/3507 we implemented a check so that `listunspent` returns an error if an unrecognized option is given. I figured I might as well adapt the code and throw up a PR here.

fixes issue #19678 UBSan implicit-integer-sign-change
Credit to Eugene (Crypt-iQ) for finding and reporting the issue
and to Vasil Dimov (vasild) for the original suggestion
and otherwise log that an unknown INV type was received.
In INV processing, when handling transaction type inv messages,
ToGenTxid() expects that we constructed the CInv ourselves or
that we verified that it is for a transaction type CInv.
Therefore, change this `else` branch into an `else if (inv.GenMsgTx())`
to make this safer and log any INVs that fall through.
The nFetchFlags code can be removed here because GetFetchFlags() can only add
the MSG_WITNESS_FLAG, which is added to the CInv::type field. That CInv is only
passed to AlreadyHave() or ToGenTxid(), and neither of those functions do
anything different depending on whether the CInv type is MSG_TX or
MSG_WITNESS_TX.

This is needed to allow bitcoin-gui to connect to existing node process with
-ipcconnect instead of spawning a new process. It's possible to spawn a new
bitcoin-node process without knowing the current data dir or network, but
connecting to an existing bitcoin-node requires knowing the datadir and network
first.
No change in behavior. Replacing references with pointers allows Node interface
creation to be delayed until later during gui startup next commit to support
implementing -ipcconnect option
Change gui code to use gArgs, Params() functions directly instead of going
through interfaces::Node.
Remotely accessing bitcoin-node ArgsManager from bitcoin-gui works fine in
https://github.com/bitcoin/bitcoin/pull/10102, when bitcoin-gui spawns a new
bitcoin-node process and controls its startup, but for bitcoin-gui to support
-ipcconnect option in https://github.com/bitcoin/bitcoin/pull/19461 and connect
to an existing bitcoin-node process, it needs ability to parse arguments itself
before connecting out.
This change also simplifies https://github.com/bitcoin/bitcoin/pull/10102 a
bit, by making the bitcoin-gui -> bitcoin-node startup sequence more similar to
the bitcoin-node -> bitcoin-wallet startup sequence where the parent process
parses arguments and passes them to the child process instead of the parent
process using the child process to parse arguments.
e2aa1a585a util: make EncodeBase64 consume Spans (Sebastian Falbesoner)
2bc207190e util: make EncodeBase32 consume Spans (Sebastian Falbesoner)
Pull request description:
To simplify the interface of the Base32/Base64 encoding functions for raw data, this PR changes them from taking two arguments (pointer and length) to just one Span. Most calls to `EncodeBase64` pass data from `CDataStream` instances, which unfortunately internally work with `char*` pointers rather than `unsigned char*`, but thanks to the recently introduced `MakeUCharSpan` helper, converting them is quite easy.

fa33bc2dab init: Capture copy of blocknotify setting for BlockNotifyCallback (MarcoFalke)
fa40017706 init: Pass reference to ArgsManager around instead of relying on global (MarcoFalke)
Pull request description:
The gArgs global has several issues:
* gArgs is used by each process (bitcoind, bitcoin-qt, bitcoin-wallet, bitcoin-cli, bitcoin-tx, ...), but it is hard to determine which arguments are actually used by each process. For example arguments that have never been registered, but are still used, will always return the fallback value.
* Tests may run several sub-tests, which need different settings. So globals will have to be overwritten, but that is fragile on its own: e.g. https://github.com/bitcoin/bitcoin/pull/19704#issuecomment-678259092 or #19511
The goal is to remove gArgs, but as a first step in that direction this pull will change gArgs in init to use a passed-in reference instead.

102867c587 net: change CNetAddr::ip to have flexible size (Vasil Dimov)
1ea57ad674 net: don't accept non-left-contiguous netmasks (Vasil Dimov)
Pull request description:
(chopped off from #19031 to ease review)
Before this change `CNetAddr::ip` was a fixed-size array of 16 bytes,
not being able to store larger addresses (e.g. TORv3) and encoded
smaller ones as 16-byte IPv6 addresses.
Change its type to `prevector`, so that it can hold larger addresses and
do not disguise non-IPv6 addresses as IPv6. So the IPv4 address
`1.2.3.4` is now encoded as `01020304` instead of
`00000000000000000000FFFF01020304`.
Rename `CNetAddr::ip` to `CNetAddr::m_addr` because it is not an "IP" or
"IP address" (TOR addresses are not IP addresses).
In order to preserve backward compatibility with serialization (where
e.g. `1.2.3.4` is serialized as `00000000000000000000FFFF01020304`)
introduce `CNetAddr` dedicated legacy serialize/unserialize methods.
Adjust `CSubNet` accordingly. Still use `CSubNet::netmask[]` of fixed 16
bytes, but use the first 4 for IPv4 (not the last 4). Do not accept
invalid netmasks that have 0-bits followed by 1-bits and only allow
subnetting for IPv4 and IPv6.

A netmask that contains 1-bits after 0-bits (the 1-bits are not
contiguous on the left side) is invalid [1] [2].
The code before this PR used to parse and accept such
non-left-contiguous netmasks. However, a coming change that will alter
`CNetAddr::ip` to have flexible size would make juggling with such
netmasks more difficult, thus drop support for those.

This may be useful for writing missing eviction tests. I'd also like to add `lasttx` and `lastblk` columns to the `-netinfo` dashboard as described in https://github.com/bitcoin/bitcoin/pull/19643#issuecomment-671093420.

<jonatack> i'm running bitcoin locally with nLastBlockTime and nLastTXTime added to getpeerinfo for my peer connections dashboard

- Adds new RPC `listindices` (placed in Util section)
- That RPC only lists the actively running indices
- For each index it gives the name, whether it is synced and up to which block height it is synced

71e0f07e9c util: remove unused c-string variant of atoi64() (Sebastian Falbesoner)
Pull request description:
This is another micro-PR "removing old cruft with potentially sharp edges" (quote by practicalswift, see #19739). Gets rid of the c-string variant of the function `atoi64()`, which is only used in fuzzers and on one place with `wallet/wallet.h` (where it is originally a `std::string` anyways and uses `.c_str()` -- this method call can simply be removed.)

356988e200 util: make EncodeBase58Check consume Spans (Sebastian Falbesoner)
f0fce0675d util: make EncodeBase58 consume Spans (Sebastian Falbesoner)
Pull request description:
This PR improves the interfaces for the functions `EncodeBase58{Check}` by using Spans, in a similar fashion to e.g. PRs #19660, #19687. Note that on the master branch there are currently two versions of `EncodeBase58`: one that takes two pointers (marking begin and end) and another one that takes a `std::vector<unsigned char>` const-ref. The PR branch only leaves one generic Span-interface, both simplifying the interface and allowing more generic containers to be passed. The same is done for `EncodeBase58Check`, where only one interface existed but it's more generic now (e.g. a std::array can be directly passed, as done in the benchmarks).

7f13dfb587 test: test the implicit avoid partial spends functionality (Karl-Johan Alm)
b82067bf69 wallet: try -avoidpartialspends mode and use its result if fees are below threshold (Karl-Johan Alm)
Pull request description:
The `-avoidpartialspends` feature is normally disabled, as it may affect the optimal fee for payments. This PR introduces a new parameter `-maxapsfee` (max avoid partial spends fee) which acts on the following values:
* -1: disable partial spend avoidance completely (do not even try it)
* 0: only do partial spend avoidance if fees are the same or better as the regular coin selection
* 1..∞: use APS variant if the absolute fee difference is less than or equal to the max APS fee
For values other than -1, the code will now try partial spend avoidance once, and if that gives a value within the accepted range, it will use that.
Example: -maxapsfee=0.00001000 means the wallet will do regular coin select, APS coin select, and then pick AKS iff the absolute fee difference is <= 1000 satoshi.
Edit: updated this to reflect the fact we are now using a max fee.

767073fb96 Shrink CAddress from 48 to 40 bytes on x64 (Vasil Dimov)
Pull request description:
`CAddress` inherits `CService` which is 28 bytes (on 64 bit machines).
`CAddress` then adds two member variables - one that requires 4 byte
alignment (`nTime`) and one that requires 8 byte alignment
(`nServices`).
Declare the smaller one first so that it fits in bytes 29..32.
On 32 bit machines this change has no effect and `CAddress` remains 40

Pull request description:
A rebase of #13084 which additionally modifies the test code (unaddressed in the original, assuming sipa is too busy to deal with this at the moment).
Relatively simple bugfix so it'd be good to have merged soon.
Turning OP_1NEGATE into 0x0181 results in a larger-than-necessary data push instead of just actually using the OP_1NEGATE opcode (0x4f). This fails the minimal push rule of BIP 62 and makes the result non-standard.

e7448d6680 wallet: Don't override signing errors (Fabian Jahr)
Pull request description:
While reviewing #17204 I noticed that the errors in `input_errors` from `::SignTransaction` where being overridden by `CWallet::SignTransaction`. For example, a Script related error led to incomplete signature data which led to `CWallet::SignTransaction` reporting that keys were missing, which was a less precise error than the original one.
Additionally, the error `"Input not found or already spent"` is [duplicated in `sign.cpp`](c7b4968552/src/script/sign.cpp (L481)), so the error here is redundant at the moment. So technically the whole error block could be removed, I think. However, this code is affected by the ongoing work on the wallet so there might be a reason why these errors are here. But even if there is a reason to keep them, I don't think existing, potentially more precise errors should be overridden here unless we want to hide them from the users. I am looking for feedback if this is a work in progress state where these errors could be more useful in the future or if they can be removed.
On testing: even though [the errors in `CWallet` are covered](https://marcofalke.github.io/btc_cov/total.coverage/src/wallet/wallet.cpp.gcov.html), all tests still pass after removing them. I am not sure if there is a desire to cover these specific error messages, tests in `test/functional/rpc_signrawtransaction.py` seem to aim for a more generic approach.

fa89ca9b5b refactor: Use C++11 range based for loops to simplify rpc code (MarcoFalke)
fa459bdc87 rpc: Treat all args after a hidden arg as hidden as well (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in misc. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

f110b7c722 rpc: document returned error fields as optional if applicable (Sebastian Falbesoner)
Pull request description:
The following RPCs return error fields (named `"error"` or `"errors"`) that are optional, but don't show up as optional in the help text yet:
* `analyzepsbt`
* `estimatesmartfee`
* `signrawtransactionwithkey`
* `signrawtransactionwithwallet`
The following RPC has the errors field already marked as optional, but doesn't match the usual format in the description (like `"if there are any"` in parantheses):
* `estimaterawfee`
This PR adds the missing optional flags and adapts the description strings. Inspired by a recent PR #19634 by justinmoon.
The instances were found via `git grep "RPCResult.*\"error"`. Note that there is one RPC so far where the return error is not optional (i.e. in case of no error, the field is included in the result, but is just empty), namely `bumpfee`.

c133cdcdc3 Cap listsinceblock target_confirmations param (Adam Stein)
Pull request description:
This addresses an issue brought up in #19587.
Currently, the `target_confirmations` parameter to `listsinceblock` is not checked for being too large. When `target_confirmations` is greater than one more than the current number of blocks, `listsinceblock` fails with error code -1. In comparison, when `target_confirmations` is less than 1, a -8 "Invalid parameter" error code is thrown.
This PR fixes the issue by returning a -8 "Invalid parameter" error if the `target_confirmations` value corresponds to a block with more confirmations than the genesis block. This happens if `target_confirmations` exceeds one more than the number of blocks.

25e1d0bf41 RPCConsole, take initial chaintip data as parameter (Jonas Schnelli)
Pull request description:
During the GUI startup, there is currently an accumulation of cs_main locks due to setting initial chain state values at multiple locations (in the GUI main thread).
This PR tries to cache the initial chain state (tip height, tip time, best header, etc.) short after loading the blockindex.
The cached values are then used instead of fetching them again (and thus locking `cs_main`) during setting the client model.
This should fix the initial GUI blocking often experienced during or short after the splashscreen.
On mac, best tested together with #19007.

Previously, listsinceblock would fail with error code -1 when the
target_confirmations exceeded the number of confirmations of the genesis
block. This commit allows target_confirmations to refer to a lastblock
hash with more confirmations than exist in the chain by setting the
lastblock hash to the genesis hash in this case. This allows for
`listsinceblock "" 6` to not fail if the block count is less than 5
which may happen on regtest.
Includes update to the functional test for listsinceblock to test for
this case.
a51d0ad2de rpc: Improve addnode remove command error message (Fabian Jahr)
Pull request description:
The `addnode` RPC with the `remove` command parameter is used to remove a node from the "added nodes". It did not have test coverage and in case of failure to remove the node it responded with the confusing message "Error: Node has not been added.".
This PR adds test coverage and introduces a new error code as well as changes the error message to something that makes sense.

`CAddress` inherits `CService` which is 28 bytes (on 64 bit machines).
`CAddress` then adds two member variables - one that requires 4 byte
alignment (`nTime`) and one that requires 8 byte alignment
(`nServices`).
Declare the smaller one first so that it fits in bytes 29..32.
On 32 bit machines this change has no effect and `CAddress` remains 40
bytes.
Hold a reference to connman rather than a pointer because:
- PeerLogicValidation can't run without a connman
- The pointer never gets reseated
The alternative is to always assert that the pointer is non-null before
dereferencing.
Change the name from connman to m_connman at the same time to conform
with current style guidelines.

f26502e9fc [addrman] Specify max addresses and pct when calling GetAddresses() (John Newbery)
Pull request description:
Currently addrman only allows a maximum of 1000 records or 23% of all records to be returned in a call to `GetAddr()`. Relax this limit and have the client specify the max records they want. For p2p, behaviour is unchanged (but the rate limiting is set inside net_processing, where it belongs). For RPC, `getnodeaddresses` can now return the complete addrman, which is helpful for testing and monitoring.
Also add a test-only RPC `addpeeraddress`, which adds an IP address:port to addrman. This is helpful for testing (eg #18991).

Misbehavior tracking state is now contained in Peer instead of
CNode. It is no longer guarded by cs_main, but instead by a
dedicated m_misbehavior_mutex lock.
This allows us to remove 14 cs_main locks from net_processing.
CAddrMan.GetAddr() would previously limit the number and percentage of
addresses returned (to ADDRMAN_GETADDR_MAX (1000) and
ADDRMAN_GETADDR_MAX_PCT (23) respectively). Instead, make it the callers
responsibility to specify the maximum addresses and percentage they want
returned.
For net_processing, the maximums are MAX_ADDR_TO_SEND (1000) and
MAX_PCT_ADDR_TO_SEND (23). For rpc/net, the maximum is specified by the
client.

3f1b7140e9 scripted-diff: Rename OneShot to AddrFetch (Amiti Uttarwar)
Pull request description:
**This is part 1 of #19315, which enables the ability to test `outbound` and `block-relay-only` connections from the functional tests.** Please see that PR for more information of overall functionality.
**This PR simplifies how we manage different connection types.** It introduces an enum with the various types of connections so we can explicitly define the connection type. The existing system relies on a series of independent flags, then has asserts scattered around to ensure that conflicting flags are not enabled at the same time. I find this approach to be both brittle and confusing. While making these changes, I found a small bug due to the silent assumptions.
This PR also proposes a rename from `OneShot` to `AddrFetch`. I find the name `OneShot` to be very confusing, especially when we also have `onetry` manual connections. Everyone I've talked to offline has agreed that the name is confusing, so I propose a potential alternative. I think this is a good opportunity for a rename since I'm creating an enum to explicitly define the connection types.
(some context for the unfamiliar: `oneshot` or `addrfetch` connections are short-lived connections created on startup. They connect to the seed peers, send a `getaddr` to solicit addresses, then close the connection.)
Overview of this PR:
* rename `oneshot` to `addrfetch`
* introduce `ConnectionType` enum
* one by one, add different connection types to the enum
* expose the `conn_type` on CNode, and use this to reduce reliance on flags (& asserts)
* fix the bug in counting different type of connections
* some additional cleanup to simplify logic and make expectations explicit/inclusive rather than implicit/exclusive.

Instead of having callers set the fees, effective values, and filtering
of outputs, do these within OutputGroups themselves as member functions.
m_fee and m_long_term_fee is added to OutputGroup to track the fees of
the OutputGroup.
4c0731f9c5 Deduplicate missing parents of orphan transactions (Suhas Daftuar)
8196176243 Rewrite parent txid loop of requested transactions (Suhas Daftuar)
Pull request description:
I noticed a couple of places recently where we loop over all inputs of a transaction in order to do some processing on the txids we find in those inputs. There may be thousands of inputs in a transaction, and the same txid may appear many times. In a couple of places in particular, we loop over those txids and add them to a rolling bloom filter; doing that multiple times for the same txid wastes entries in that filter.
This PR fixes that in two places relating to transaction relay: one on the server side, where we look for parent transactions of a tx that we are delivering to a peer to ensure that getdata requests for those parents will succeed; and the other on the client side, where when we process an orphan tx we want to loop over the parent txids and ensure that all are eventually requested from the peer who provided the orphan.
This addresses a couple of [related](https://github.com/bitcoin/bitcoin/pull/19109#discussion_r455197217) [comments](https://github.com/bitcoin/bitcoin/pull/19109#discussion_r456820373) left in #19109.

Extract logic that check multiple connection types into interface functions &
structure as switch statements. This makes it very clear what touch points are
for accessing `m_conn_type` & using the switch statements enables the compiler
to warn if a new connection type is introduced but not handled for these cases.
Make the connection counts explicit and extract into interface functions around
m_conn_type. Using explicit counting and switch statements where possible
should help prevent counting bugs in the future.
The desired logic is for us to only open feeler connections after we have hit
the max count for outbound full relay connections. A short lived AddrFetch
connection (previously called oneshot) could cause ThreadOpenConnections to
miscount and mistakenly open a feeler instead of full relay.
For a couple of years, Tor documentation has made
the term hidden service obsolete, in favor of onion
service.

edc316020e test: Remove duplicate NodeContext hacks (Russell Yanofsky)
Pull request description:
Qt tests currently are currently using two NodeContext structs at the same time, one in interfaces::NodeImpl::m_context, and the other in BasicTestingSetup::m_node, and the tests have hacks transferring state between them.
Fix this by getting rid of the NodeImpl::m_context struct and making it a pointer. This way a common BitcoinApplication object can be used for all qt tests, but they can still have their own testing setups.
Non-test code is changing but non-test behavior is still the same as before.
Motivation for this PR is to be able to remove the "std::move(test.m_node.connman)" and mempool hacks for swapping individual NodeContext members in Qt tests, because followup PR #19099 adds yet another member (wallet_client) that needs to be swapped. After this change, the whole NodeContext struct can be swapped instead of individual members, so the workarounds are less fragile and invasive.

9f88ded82b test addition of unknown segwit spends to txid reject filter (Gregory Sanders)
7989901c7e Add txids with non-standard inputs to reject filter (Suhas Daftuar)
Pull request description:
Our policy checks for non-standard inputs depend only on the non-witness
portion of a transaction: we look up the scriptPubKey of the input being
spent from our UTXO set (which is covered by the input txid), and the p2sh
checks only rely on the scriptSig portion of the input.
Consequently it's safe to add txids of transactions that fail these checks to
the reject filter, as the witness is irrelevant to the failure. This is helpful
for any situation where we might request the transaction again via txid (either
from txid-relay peers, or if we might fetch the transaction via txid due to
parent-fetching of orphans).
Further, in preparation for future witness versions being deployed on the
network, ensure that WITNESS_UNKNOWN transactions are rejected in
AreInputsStandard(), so that transactions spending v1 (or greater) witness
outputs will fall into this category of having their txid added to the reject
filter.

Prerequisite for external signer support in #16546. Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).
This adds a new dependency [boost process](https://github.com/boostorg/process/tree/boost-1.64.0). This is part of Boost since 1.64 which is part of `depends`. Because the minimum Boost version is 1.47, this functionality is skipped for older versions of Boost.
Use `./configure --with-boost-process` to opt in, which checks for the presence of Boost::Process.
We add `UniValue runCommandParseJSON(const std::string& strCommand)` to `system.{h,cpp}` which calls an arbitrary command and processes the JSON returned by it. This is currently only called by the test suite.
~For testing purposes this adds a new regtest-only RPC method `runcommand`, as well as `test/mocks/command.py` used by functional tests.~ (this is no longer the case)
