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.

Pull request description:
New contributors are often confused by the terminology in the test framework, and what the difference between a _node_ and a _peer_ is. To summarize:
- a 'node' is a bitcoind instance. This is the thing whose behavior is being tested. Each bitcoind node is managed by a python `TestNode` object which is used to start/stop the node, manage the node's data directory, read state about the node (eg process status, log file), and interact with the node over different interfaces.
- one of the interfaces that we can use to interact with the node is the p2p interface. Each connection to a node using this interface is managed by a python `P2PInterface` or derived object (which is owned by the `TestNode` object). We can open zero, one or many p2p connections to each bitcoind node. The node sees these connections as 'peers'.
For historic reasons, the word 'mininode' has been used to refer to those p2p interface objects that we use to connect to the bitcoind node (the code was originally taken from the 'mini-node' branch of https://github.com/jgarzik/pynode/tree/mini-node). However that name has proved to be confusing for new contributors, so rename the remaining references.

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.

02fbe3ae0b net: add nLastBlockTime/TXTime to CNodeStats, CNode::copyStats (Jon Atack)
Pull request description:
This PR adds inbound peer eviction criteria `nLastBlockTime` and `nLastTXTime` to `CNodeStats` and `CNode::copyStats`, which then allows exposing them in the next commit as `last_transaction` and `last_block` Unix Epoch Time fields in RPC `getpeerinfo`.
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.
Relevant discussion at the p2p irc meeting http://www.erisian.com.au/bitcoin-core-dev/log-2020-08-11.html#l-549:

<jonatack> i was specifically trying to observe and figure out how to test https://github.com/bitcoin/bitcoin/issues/19500
<jonatack> which made me realise that i didn't know what was going on with my peer conns in enough detail
<jonatack> i'm running bitcoin locally with nLastBlockTime and nLastTXTime added to getpeerinfo for my peer connections dashboard
<jonatack> sipa: is there a good reason why that (eviction criteria) data is not exposed through getpeerinfo currently?
<sipa> jonatack: nope; i suspect just nobody ever added it
<jonatack> sipa: thanks. will propose.

cf0681133a build: disable D-Bus on Android by default (Igor Cota)
Pull request description:
I've been trying to build for Android on different OSes/Gitian with varying success. Build system is quite the beast and sometimes it doesn't get it right. To make sure it does these three little tweaks make the Android build more robust:
- disable D-Bus (Android doesn't support it and has its own way to trigger notifications)
- don't flag `-lpthread` when linking Boost, [Bionic has built-in support](https://stackoverflow.com/questions/30801752/android-ndk-and-pthread)
- ~~add `-static-libstdc++` to linker flags. This avoids having to bundle `libc++_shared` with CLI apps, still necessary with `bitcoin-qt` though (thanks Sjors)~~
I think these are small and fairly straightforward so I put them all into this one PR.

- 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

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).
