Merge #19740: [0.20] wallet: Simplify and fix CWallet::SignTransaction
6a326cf66f04948ffe729e5540a69e159a7840ad tests: Test that a fully signed tx given to signrawtx is unchanged (Andrew Chow)
2d48d7dcfb93eeec36dd6f5cbad289b89ec69324 Simplify and fix CWallet::SignTransaction (Andrew Chow)

Pull request description:

  Backport `CWallet::SignTransaction` from master which is simpler and not broken.

  Previously `CWallet::SignTransaction` would return false for a fully signed transaction. This is a regression and obviously incorrect - a fully signed transaction is always complete. This occurs because `CWallet::SignTransaction` would iterate through each input and skip any further checks if the input was already signed. It would then end up falling through to the `return false` catch-all thus erroneously saying a fully signed transaction is incomplete. The change to attempting to use all `ScriptPubKeyMan`s fixes this problem since the `LegacyScriptPubKeyMan` (the only spkm implemented in 0.20) will verify inputs during its signing attempt and correctly return that it is complete when the inputs verify. Thus a fully signed transaction will be correctly identified as complete, `LegacyScriptPubKeyMan::SignTranaction` will return true, and so `CWallet::Transaction` will return true too.

  Note that this is not a backport of any specific commit. Rather it is the end result of the changes we have made to this function in master.

  Fixes #19737

tests: Test that a fully signed tx given to signrawtx is unchanged
Tests that a fully signed transaction given to
signrawtransactionwithwallet is both unchanged and marked as complete.
This tests for a regression in 0.20 where the transaction would not be
marked as complete.

Pull request description:

  The 0.20 branch has bugfixes that should be released. However, a tag can currently not be created because the latest merge introduced a regression and is not a bugfix (https://github.com/bitcoin/bitcoin/pull/20317#issuecomment-723754509, https://github.com/bitcoin/bitcoin/pull/20317#issuecomment-727624755).

  Fix that by reverting the last merge. Can be reviewed by re-doing the revert or calling `git diff HEAD HEAD~2 | wc` and observing an empty diff.

Pull request description:

  We want wtxid relay to be widely deployed before taproot activation, so it should be backported to v0.20.

  The main difference from #18044 is removing the changes to the unbroadcast set (which was only added post-v0.20). The rest is mostly minor rebase conflicts (eg connman changed from a pointer to a reference in master, etc).

  We'll also want to backport #19569 after that's merged.

build: fix mutex detection when building bdb on macOS
Starting with the Clang shipped with Xcode 12, Apple has enabled
-Werror=implicit-function-declaration by default. This causes bdbs mutex
detection to fail when building on macOS (not cross-compiling):

checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation

as previously emitted warnings are being turned into errors. i.e:

error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration]

Append -Wno-error=implicit-function-declaration to cflags so that
-Wimplicit-function-declaration returns to being a warning, and the
configure checks will succeed.

Fixes #19411.

Merge #20142: [0.20] build: set minimum required Boost to 1.48.0
3562c15be3dbf725197d719d58c8d78e2f2c6779 build: set minimum required Boost to 1.48.0 (fanquake)

Pull request description:

  Due to the use of [`boost::filesystem::canonical()`](80aa83aa40/src/wallet/load.cpp (L21)), the minimum required
  version of Boost is actually 1.48.0. Use of canonical was introduced
  in #14146.

  See also [Boost filesystem 1.48.0 release notes](6b5e38134a/doc/release_history.html (L508)). Also discussed in #20080.

879a3cf2c2 Make TX_WITNESS_STRIPPED its own rejection reason
Previously, TX_WITNESS_MUTATED could be returned during transaction validation
for either transactions that had a witness that was non-standard, or for
transactions that had no witness but were invalid due to segwit validation
rules.

However, for txid/wtxid-relay considerations, net_processing distinguishes the
witness stripped case separately, because it affects whether a wtxid should be
able to be added to the reject filter. It is safe to add the wtxid of a
witness-mutated transaction to the filter (as that wtxid shouldn't collide with
the txid, and hence it wouldn't interfere with transaction relay from
txid-relay peers), but it is not safe to add the wtxid (== txid) of a
witness-stripped transaction to the filter, because that would interfere with
relay of another transaction with the same txid (but different wtxid) when
relaying from txid-relay peers.

Also updates the comment explaining this logic, and explaining that we can get
rid of this complexity once there's a sufficient deployment of wtxid-relaying
peers on the network.

c1d6a1003d Delay getdata requests from peers using txid-based relay
Using both txid and wtxid-based relay with peers means that we could sometimes
download the same transaction twice, if announced via two different hashes from
different peers.

Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have
at least one wtxid-based peer.

2599277e9c Add support for tx-relay via wtxid
This adds a field to CNodeState that tracks whether to relay transactions with
that peer via wtxid, instead of txid. As of this commit the field will always
be false, but in a later commit we will add a way to negotiate turning this on
via p2p messages exchanged with the peer.

be1b7a8916 Add wtxids to recentRejects
Previously, we only added txids to recentRejects if we were sure that the
transaction couldn't have had the wrong witness (either because the witness was
malleated or stripped).

In preparation for wtxid-based relay, we can observe that txid == wtxid for
transactions that have no witness, and add the wtxid of rejected transactions,
provided the transaction wasn't a witness-stripped one. This means that we now
add more data to the filter (as prior to this commit, any transaction with a
witness that failed to be accepted was being skipped for inclusion in the
filter) but witness malleation should still not interfere with relay of a valid
segwit transaction, because the txid of a segwit transaction would not be added
to the filter after failing validation.

In the future, having wtxids in the recent rejects filter will allow us to
skip downloading the same wtxid multiple times, once our peers use wtxids for
transaction relay.

Also add the txid to recentRejects if the transaction failed for
TX_INPUTS_NOT_STANDARD.

73845211d1 Add wtxids of confirmed transactions to bloom filter
This is in preparation for wtxid-based invs (we need to be able to tell whether
we AlreadyHave() a transaction based on either txid or wtxid).

This also double the size of the bloom filter, which is overkill, but still
uses a manageable amount of memory.
