6a326cf66f tests: Test that a fully signed tx given to signrawtx is unchanged (Andrew Chow)
2d48d7dcfb 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.

fa074d2c7b Revert "Merge #19606: Backport wtxid relay to v0.20" (MarcoFalke)
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.

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.
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.
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.
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.
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.
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.

This patch improves performance and resource usage around IP
addresses that are banned for misbehavior. They're already not
actually banned, as connections from them are still allowed,
but they are preferred for eviction if the inbound connection
slots are full.
Stop treating these like manually banned IP ranges, and instead
just keep them in a rolling Bloom filter of misbehaving nodes,
which isn't persisted to disk or exposed through the ban
framework. The effect remains the same: preferred for eviction,
avoided for outgoing connections, and not relayed to other peers.
Also change the name of this mechanism to better reflect reality;
they're not banned, just discouraged.
Contains release notes and several interface improvements by
John Newbery.
