- change the value returned in the RPC getaddressinfo `labels` field to an array
of label name strings
- deprecate the previous behavior of returning a JSON hash structure containing
label `name` and address `purpose` key/value pairs
- update the relevant tests
If after a backup, an address is issued beyond the initial
keypool range and none of the addresses in this range
is seen onchain, if a wallet is restored from backup, even in
case of rescan, funds may be loss due to the look-ahead
buffer not being incremented and so restored wallet not detecting
onchain out-of-range address as derived from its seed.
This scenario is theoretically unavoidable due to the requirement
of the keypool to have a max size. However, given the default
keypool size, this is unlikely. Document better keypool size
implications to avoid user setting a too low value.

ea50e34b28 keypool: Move opportunistic TopUps from LegacyScriptPubKeyMan to CWallet and ReserveDestination (Andrew Chow)
bb2c8ce23c keypool: Remove superfluous topup from CWallet::GetNewChangeDestination (Andrew Chow)
Pull request description:
* The `TopUp()` in `CWallet::GetNewChangeDestination` is unnecessary as currently m_spk_man calls TopUp further down the call stack inside LegacyScriptPubKeyMan::ReserveKeyFromKeyPool (called by LegacyScriptPubKeyMan::GetReservedDestination). This also lets us prepare for future changes with multiple ScriptPubKeyMans in the wallet.
* An opportunistic `TopUp()` is moved from `LegacyScriptPubKeyMan::GetNewDestination` to `CWallet::GetNewDestination`.
* Another opportunistic `TopUp()` is moved from `LegacyScriptPubKeyMan::ReserveKeyFromKeyPool`
Moving opportunistic TopUps ensures that ScriptPubKeyMans will always be topped up before requesting Destinations from them as we cannot always rely on future ScriptPubKeyMan implementaions topping up internally.

Pull request description:
* The `pwallet->CanGetAddresses()` call in `ReserveDestination::GetReservedDestination` to `LegacyScriptPubKeyMan::GetReservedDestination` so that the sanity check results in a failure when a `ScriptPubKeyMan` individually cannot get a destination, not when any of the `ScriptPubKeyMan`s can't.
* `ScriptPubKeyMan::GetReservedDestination` is changed to return the destination so that future `ScriptPubKeyMan`s can return destinations constructed in other ways. This is implemented for `LegacyScriptPubKeyMan` by moving key-to-destination code from `CWallet` to `LegacyScriptPubKeyMan`
* In order for `ScriptPubKeyMan` to be generic and work with future `ScriptPubKeyMan`s, `ScriptPubKeyMan::ReturnDestination` is changed to take a `CTxDestination` instead of a `CPubKey`. Since `LegacyScriptPubKeyMan` still deals with keys internally, a new map `m_reserved_key_to_index` is added in order to track the keypool indexes that have been reserved.
* A bug is fixed in how the total keypool size is calculated as it was omitting `set_pre_split_keypool` which is a bug.

In order for ScriptPubKeyMan to be generic and work with future
ScriptPubKeyMans, ScriptPubKeyMan::ReturnDestination is changed to
take a CTxDestination instead of a CPubKey. Since LegacyScriptPubKeyMan
still deals with keys internally, a new map m_reserved_key_to_index is
added in order to track the keypool indexes that have been reserved.
The CPubKey argument of KeepDestination is also removed so that it is
more generic. Instead of taking a CPubKey or a CTxDestination, we just use
the nIndex given to find the pubkey.
Addresses are determined by LegacyScriptPubKeyMan::GetReservedDestination
instead of ReserveDestination::GetReservedDestination as other ScriptPubKeyMan
implementations may construct addresses differently
This does not change behavior.
eadd1304c8 tests: Add a test for funding with sufficient preset inputs and subtractFeeFromOutputs (Andrew Chow)
ff330badd4 Default to bnb_used = false as there are many cases where BnB is not used (Andrew Chow)
Pull request description:
#17290 introduced a bug where, when we had preset inputs that covered the amount being sent and subtractFeeFrromOutputs was being used, transaction funding would result in a `Fee exceeds maximum configured by -maxtxfee` error. This was happening because we weren't setting `bnb_used = false` when the preset inputs were used as it should have been. This resulted in a too high fee because the change would go to fees accidentally.
Apparently this particular case doesn't have a test, so I've added one as well.

Pull request description:
This PR is a continuation of the work in https://github.com/bitcoin/bitcoin/pull/12892.
Main motivations:
- There is currently no test coverage for the getaddressinfo `labels` response. Coverage here is a prerequisite before deprecating the `label` response or adding multiple labels per address.
- `bitcoin-cli help getaddressinfo` returns a few content errors, difficult-to-read formatting, and no explanation why it returns both `label` and `labels` and how they relate, which can be confusing for application developers.
Changes by order of commits:
- [x] improve/fix getaddressinfo RPCHelpman layout formatting
- [x] improve/fix getaddressinfo RPCHelpman content
- [x] clarify the `label` and `labels` fields in getaddressinfo RPCHelpman
- [x] update getaddressinfo RPCExamples addresses to bech32
- [x] add getaddressinfo code docs
- [x] add a `listlabels` test assertion in wallet_labels.py
- [x] add missing getaddressinfo `labels` test coverage and improve the existing `label` tests
Here are gists of the CLI help output:

An opportunistic TopUp is moved from LegacyScriptPubKeyMan::GetNewDestination
to CWallet::GetNewDestination. Another opportunistic TopUp is moved from
LegacyScriptPubKeyMan::ReserveKeyFromKeyPool (called by LegacyScriptPubKeyMan::GetReservedDestination)
to ReserveDestination::GetReservedDestination.
Moving opportunistic TopUps ensures that ScriptPubKeyMans will always
be topped up before requesting Destinations from them as we cannot
always rely on future ScriptPubKeyMan implementaions topping up internally.
As such, it is also unnecessary to keep the TopUp calls in the
LegacyScriptPubKeyMan functions so they are moved.
This does not change behavior as TopUp calls are moved up the call stack.
This does not change behavior. This TopUp() is unnecessary as currently
m_spk_man calls TopUp further down the call stack inside
LegacyScriptPubKeyMan::ReserveKeyFromKeyPool (called by LegacyScriptPubKeyMan::GetReservedDestination)
By removing this here, we also prepare for future changes where CWallet
has multiple ScriptPubKeyMans instead of m_spk_man.
Call LegacyScriptPubKeyMan::CanGetAddresses directly instead of calling
CWallet::CanGetAddresses to only query the relevant key manager
This is a minor change in behavior: call now only happens if a new key needs to
be reserved, since if a key is already reserved it might fail unnecessarily.
This change also serves as a sanity check

First commit is a refactor that makes the address type a class member.

Work starter to remove Chain::Lock interface by adding m_last_block_processed_height in CWallet and m_block_height in CMerkleTx to avoid GetDepthInMainChain having to keep a lock . Once this one done, it should ease work to wipe out more cs_main locks from wallet code.
I think it's ready for a first round of review before to get further.
- `BlockUntilSyncedToCurrent` : restrain isPotentialTip to isTip because we want to be sure that wallet see BlockDisconnected callbacks if its height differs from the Chain one. It means during a reorg, an RPC could return before the BlockDisconnected callback had been triggered. This could cause a tx that had been included in the disconnected block to be displayed as confirmed, for example.
~~- `AbandonTransaction` : in case of conflicted tx (nIndex = -1), we set its m_block_height to the one of conflicting blocks, but if this height is superior to CWallet::m_last_block_processed_height, that means tx isn't conflicted anymore so we return 0 as tx is again unconfirmed~~ After #16624, we instead rely on Confirmation.
~~- `AddToWalletIfInvolvingMe`: in case of block disconnected, transactions are added to mempool again, so we need to replace old txn in `mapWallet` with a height set to zero so we remove check on block_hash.IsNull~~ Already done in #16624

We don't remove yet Chain locks as we need to preserve lock
order with CWallet one until swapping at once to avoid
deadlock failures (spotted by --enable-debug)
is exact match
In the next commit, we start using BlockConnected/BlockDisconnected
callbacks to establish tx depth, rather than querying the chain
directly.
Currently, BlockUntilSyncedToCurrentChain will return early if
the best block processed by the wallet is a descendant of the node'tip.
That means that in the case of a re-org, it won't wait for the
BlockDisconnected callbacks that have been enqueued during the re-org
but have not yet been triggered in the wallet.
Change BlockUntilSyncedToCurrentChain to only return early if the
wallet's m_last_block_processed matches the tip exactly. This ensures
that there are no BlockDisconnected or BlockConnected callbacks
in-flight.
At wallet loading, we rely on chain state querying to retrieve
height of txn, to do so we ensure that lock order is respected
between cs_main and cs_wallet.
If wallet loaded is the wallet-tool one, all wallet txn will
show up with a height of zero. It doesn't matter as confirmation
height is not used by wallet-tool.
Reorder arguments and document Confirmation calls to avoid
ambiguity.

To do so we update CValidationInterface::BlockDisconnect to take a
CBlockIndex pointing to the block being disconnected.
This new parameter will be use in the following commit to establish
wallet height.

Reason for keeping the `return true` `return false` verbosity is that more code
will be added after the ReserveKeyFromKeyPool() call before returning.

dce032ce29 Make IsTrusted scan parents recursively (Jeremy Rubin)
Pull request description:
This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.
This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.
This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.
The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.
# Before `test_balance()`, we have had two nodes with a balance of 50
# each and then we:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 60 from node B to node A with fee 0.01
#
# Then we check the balances:
#
# 1) As is
# 2) With transaction 2 from above with 2x the fee
#
# Prior to #16766, in this situation, the node would immediately report
# a balance of 30 on node B as unconfirmed and trusted.
#
# After #16766, we show that balance as unconfirmed.
#
# The balance is indeed "trusted" and "confirmed" insofar as removing
# the mempool transactions would return at least that much money. But
# the algorithm after #16766 marks it as unconfirmed because the 'taint'
# tracking of transaction trust for summing balances doesn't consider
# which inputs belong to a user. In this case, the change output in
# question could be "destroyed" by replace the 1st transaction above.
#
# The post #16766 behavior is correct; we shouldn't be treating those
# funds as confirmed. If you want to rely on that specific UTXO existing
# which has given you that balance, you cannot, as a third party
# spending the other input would destroy that unconfirmed.
#
# For example, if the test transactions were:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 10 from node B to node A with fee 0.01
#
# Then our node would report a confirmed balance of 40 + 50 - 10 = 80
# BTC, which is more than would be available if transaction 1 were
# replaced.
The release notes have been updated to note the new behavior.

436ad43643 Fix issue with conflicted mempool tx in listsinceblock (Adam Jonas)
Pull request description:
Closes#8752 by bringing back abandoned #10470.
This now checks that returned transactions are not conflicting with any transactions that are filtered out by the given blockhash and add a functional test to prevent this in the future.
For more context, #8757 was closed in favor of #10470.
