Use -whitelist to speed up transaction relay.
The wallet_avoidreuse.py test is not intended to test transaction relay/timing,
so it should be fine to do this here.
This greatly reduces test run time variability and speeds up the test by 2-3
times on average, e.g. on my system from 20-30 seconds down to 8-10 seconds.
a6f6f77a86 QA: Add wallet_implicitsegwit to test the ability to transform keys between address types (Luke Dashjr)
Pull request description:
This makes sure the wallet recognises payments to keys via address types they weren't created with.
While we don't *want* this behaviour, it might make sense to explicitly test that it works until we remove it.

Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>

* A new class `TransportDeserializer` (unique pointer of `CNode`) is introduced, handling the network buffer reading and the decomposing to a `CNetMessage`
* **No behavioral changes** (in terms of disconnecting, punishing)
* Moves the checksum finalizing into the `SocketHandler` thread (finalizing was in `ProcessMessages` before)
The **optional last commit** makes the `TransportDeserializer` following an adapter pattern (polymorphic interface) to make it easier to later add a V2 transport protocol deserializer.
Intentionally not touching the sending part.

faeb666536 util: Add CHECK_NONFATAL and use it in src/rpc (MarcoFalke)
Pull request description:
Fixes#17181
Currently, we use `assert` in RPC code to document logic and code assumptions. However, it seems a bit extreme to abort all of Bitcoin Core on an assert failure in one of the RPC threads. I suggest to replace all `assert`s with a macro `CHECK_NONFATAL(condition)` that throws a runtime error when the condition evaluates to `false`. That runtime error will then be returned to the rpc caller and will include instructions to report the error to our issue tracker.

This moves CWallet members and methods dealing with keys to a new
LegacyScriptPubKeyMan class, and updates calling code to reference the new
class instead of CWallet.
Most of the changes are simple text replacements and variable substitutions
easily verified with:
git log -p -n1 -U0 --word-diff-regex=.
The only nontrivial chunk of code added is the new LegacyScriptPubKeyMan class
declaration, but this code isn't new and is just selectively copied and moved
from the previous CWallet class declaration. This can be verified with:
git log -p -n1 --color-moved=dimmed_zebra src/wallet/scriptpubkeyman.h src/wallet/wallet.h
or
git diff HEAD~1:src/wallet/wallet.h HEAD:src/wallet/scriptpubkeyman.h

Pull request description:
We no longer send BIP 61 REJECT messages, so there's no need to set
a REJECT code in the CValidationState object.
Note that there is a minor bug fix in p2p behaviour here. Because the
call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
then there are cases were `MaybePunishNode()` can get called where it
wasn't previously:
- when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
- when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.
Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
only internal reject code was `REJECT_HIGHFEE`, which was only set in
ATMP.
This reverts a minor bug introduced in 5d08c9c579.

89339d1460 tests: Add test for loadblock option (Fabian Jahr)
Pull request description:
Fixes#17019
Was initially part of #17044 but as the test got larger it made sense to split it into its own commit as suggested in #17019 .
This is testing the `-loadblock` option by using the scripts in `contrib/linearize` to generate a `bootstrap.dat` file and starting a disconnected node with it. So it is also testing the linearize scripts which were untested before and needed to be made available for the CI environment, hence they are added to `DIST_CONTRIB` in `Makefile.am`.

32d665c265 test: fix "tx-size-small" errors after default address change (Sebastian Falbesoner)
Pull request description:
Addresses #17043, affects RBF and BIP68 functional tests.
The "tx-size-small" policy rule rejects transactions with a non-witness size of
smaller than 82 bytes (see `src/validation.cpp:MemPoolAccept::PreChecks(...)`),
which corresponds to a transaction with 1 segwit input and 1 P2WPKH output.
Through the default address change, the created test transactions have segwit
inputs now and sending to short scriptPubKeys might violate this rule. By
bumping the dummy scriptPubKey size to 22 bytes (= the size of a P2WPKH
scriptPubKey), on all occurences the problem is solved.
The dummy scriptPubKey has the format:
```21 <21-byte-long string of 'a' or 1s>```

The majority of the test time is spent in sync_mempools() after sending to

peers via -whitelist, the inventory is transmissioned immediately rather than
on average every 5 seconds, speeding up the test by at least a factor of two:

d478a472eb test: Fix combine_logs.py for AppVeyor build (Martin Zumsande)
Pull request description:
Fixes#16894
This fixes the problem of AppVeyor builds not showing `debug.log` if a functional test fails, because the windows separator `\` doesn't work together with the regex in `combine_logs.py`.
A fix was already attempted in #16896, however, that PR became inactive and was marked "up for grabs", plus it's a really small change.
As suggested by jamesob, this PR uses `pathlib`: For the glob and to convert the path to a posix-style string, it leaves the regex as is (in contrast to #16896 which adjusted the regex).
I tested this locally on Windows and Ubuntu.

9743432034 Fix bug where duplicate PSBT keys are accepted (John L. Jegutanis)

As per the BIP 174 spec a PSBT key cannot be duplicated,
however the current code accepts key duplication.
The PSBT key/value entries can be duplicated when the value

and if those key/value entries are serialized before the non-empty ones.
For example, the following PSBT, included in the test vectors,
contains a duplicate field:

fa25f43ac5 p2p: Remove BIP61 reject messages (MarcoFalke)
Pull request description:
Reject messages (BIP 61) appear in the following settings:
* Parsing of reject messages (in case `-debug=net` is set, off by default). This has only been used for a single `LogPrint` call for several releases now. Such logging is completely meaningless to us and should thus be removed.
* The sending of reject messages (in case `-enablebip61` is set, off by default). This can be used to debug a node that is under our control. Instead of hacking this debugging into the p2p protocol, it could be more easily achieved by parsing the debug log. (Use `-printtoconsole` to have it as stream, or read from the `debug.log` file like our python function `assert_debug_log` in the test framework does)
Having to maintain all of this logic and code to accommodate debugging, which can be achieved by other means a lot easier, is a burden. It makes review on net processing changes a lot harder, since the reject message logic has to be carried around without introducing any errors or DOS vectors.

`sortedmulti()` works in the same way as `multi` does but sorts the pubkeys in the resulting scripts in lexicographic order as described in [BIP67](https://github.com/bitcoin/bips/blob/master/bip-0067.mediawiki). Note that this does not add support for BIP67 nor is BIP67 fully supported by this descriptor (which is why it is not named `multi67()`) as it does not require compressed pubkeys.
Tests from BIP67 were added and documentation was updated.

As per the BIP 174 spec a PSBT key cannot be duplicated,
however the current code accepts key duplication.
The PSBT key/value entries can be duplicated when the value
is `empty()` or `IsNull()` for `CScript` or `CTxOut` respectively
and if those key/value entries are serialized before the non-empty ones.
For example, the following PSBT, included in the test vectors,
contains a duplicate field:
```
// magic
70736274ff
// global tx
//// key
0100
//// value
2a02000000000140420f000000000017a9146e91b72d5593e7d4391e2ff44e91e985c31641f08700000000
//// separator
00
// no inputs
// outputs
//// key PSBT_OUT_WITNESSSCRIPT
0101
//// value (empty script)
00
//// key PSBT_OUT_WITNESSSCRIPT (same as the above)
0101
//// value (an OP_RETURN script)
016a
//// separator
00
```
ea4cc3a7b3 Truly decouple wallet from chainparams for -fallbackfee (Jorge Timón)
Pull request description:
Before it was 0 by default for main and 20000 for test and regtest.
Now it is 0 by default for all chains, thus there's no need to call Params().
Also now the default for main is properly documented.
Suggestion for release notes:
-fallbackfee was 0 (disabled) by default for the main chain, but 20000 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=20000 to their configuration if they weren't setting it and they want it to keep working like before.
Should I propose them to the wiki for the release notes or only after merge?
