This fully closes bitcoin#12179. Currently, in the GUI, when a user
abandons a transaction, a call is made to remove it from the list,
and another signal fires (eventually) that adds it back to the GUI
with a trash can icon.
There are no conditions where the abandoned transaction should be
directly removed from the GUI. If the underlying model changes, the
deletion will be reflected anyway.

25ef049d60 log: mempool: log removal reason in validation interface (James O'Beirne)
Pull request description:
Currently the exact reason a transaction is removed from the mempool isn't logged. It is sometimes detectable from context, but adding the `reason` to the validation interface logs (where it is already passed) seems like an easy way to disambiguate.
For example in the case of mempool expiry, the logs look like this:
```
[validationinterface.cpp:220] [TransactionRemovedFromMempool] [validation] Enqueuing TransactionRemovedFromMempool: txid=<txid> wtxid=<wtxid>
[txmempool.cpp:1050] [RemoveUnbroadcastTx] [mempool] Removed <txid> from set of unbroadcast txns before confirmation that txn was sent out
[validationinterface.cpp:220] [operator()] [validation] TransactionRemovedFromMempool: txid=<txid> wtxid=<wtxid>
[validation.cpp:267] [LimitMempoolSize] [mempool] Expired 1 transactions from the memory pool
```
There is no context-free way to know $txid was evicted on the basis of expiry. This change will make that case (and probably others) clear.

Pull request description:
A user reported on [stackexchange](https://bitcoin.stackexchange.com/q/115742/48884) that they were unable to sign for a `multi_a` script using a wallet that only had the corresponding keys (i.e. it did not have the `multi_a()` descriptor). This PR fixes this issue.
Additionally, `wallet_taproot.py` is modified to test for this scenario by having another wallet in `do_test_psbt` which contains descriptors that only have the keys involved in the descriptor being tested. `wallet_taproot.py` was also modified to create new wallets for each test case rather than sharing wallets throughout as the sharing could result in the signing wallet having the keys in a different descriptor and accidentally result in failing to detect a test failure.
The changes to the test also revealed a similar issue with `rawtr()` descriptors, which has also been fixed by checking if a descriptor can produce a `SigningProvider` for the Taproot output pubkey.

In addition to the pubkeys in hd_keypaths and tap_bip32_keypaths, also
see if the descriptor can produce a SigningProvider for the output

Also slightly refactors this area to reduce code duplication.
Taproot pubkey info was not being added for multi_a signing. The filling
of this info is moved into the common function CreateTaprootScriptSig so
that any signing of taproot scripts will include the pubkey info.

Pull request description:
#### # Context (Current Flow on Master)
In the transaction creation process, in order to select which coins the new transaction will spend,
we first obtain all the available coins known by the wallet, which means walking-through the
wallet txes map, gathering the ones that fulfill certain spendability requirements in a vector.
This coins vector is then provided to the Coin Selection process, which first checks if the user
has manually selected any input (which could be internal, aka known by the wallet, or external),
and if it does, it fetches them by searching each of them inside the wallet and/or inside the
Coin Control external tx data.
Then, after finding the pre-selected-inputs and gathering them in a vector, the Coin Selection
process walks-through the entire available coins vector once more just to erase coins that are
in both vectors. So the Coin Selection process doesn’t pick them twice (duplicate inputs inside
the same transaction).
#### # Process Workflow Changes
Now, a new method, `FetchCoins` will be responsible for:
1) Lookup the user pre-selected-inputs (which can be internal or external).
2) And, fetch the available coins in the wallet (excluding the already fetched ones).
Which will occur prior to the Coin Selection process. Which allows us to never include the
pre-selected-inputs inside the available coins vector in the first place, as well as doing other
nice improvements (written below).
So, Coin Selection can perform its main responsibility without mixing it with having to fetch
internal/external coins nor any slow and unneeded duplicate coins verification.
#### # Summarizing the Improvements:
1) If any pre-selected-input lookup fail, the process will return the error right away.
(before, the wallet was fetching all the wallet available coins, walking through the
entire txes map, and then failing for an invalid pre-selected-input inside SelectCoins)
2) The pre-selected-inputs lookup failure causes are properly described on the return error.
(before, we were returning an "Insufficient Funds" error for everything, even if the failure
was due a not solvable external input)
3) **Faster Coin Selection**: no longer need to "remove the pre-set inputs from the available coins
vector so that Coin Selection doesn't pick them" (which meant to loop-over the entire
available coins vector at Coin Selection time, erasing duplicate coins that were pre-selected).
Now, the available coins vector, which is built after the pre-selected-inputs fetching,
doesn’t include the already selected inputs in the first place.
4) **Faster transaction creation** for transactions that only use manually selected inputs.
We now will return early, as soon as we finish fetching the pre-selected-inputs and
not perform the resources expensive calculation of walking-through the entire wallet
txes map to obtain the available coins (coins that we will not use).
---------------------------
Added a new bench (f6d0bb2) measuring the transaction creation process, for a wallet with ~250k UTXO, only using the pre-selected-inputs inside coin control. Setting `m_allow_other_inputs=false` to disallow the wallet to include coins automatically.

Goal 1:
Benchmark the transaction creation process for pre-selected-inputs only.
Setting `m_allow_other_inputs=false` to disallow the wallet to include coins automatically.
Goal 2:
Benchmark the transaction creation process for pre-selected-inputs and coin selection.
-----------------------
Benchmark Setup:
1) Generates a 5k blockchain, loading the wallet with 5k transactions with two outputs each.
2) Fetch 4 random UTXO from the wallet's available coins and pre-select them as inputs inside CoinControl.
Benchmark (Goal 1):
Call `CreateTransaction` providing the coin control, who has set `m_allow_other_inputs=false` and
the manually selected coins.
Benchmark (Goal 2):
Call `CreateTransaction` providing the coin control, who has set `m_allow_other_inputs=true` and
the manually selected coins.
we are already computing the preset inputs total amount inside `PreSelectedInputs::Insert`,
which internally decides whether to use the effective value or the raw output value based on
the 'subtract_fee_outputs' flag.
so if there is an error in any of the pre-set coins, we can fail right away
without computing the wallet available coins set (calling `AvailableCoins`)
which is a slow operation as it goes through the entire wallet's txes map.
----------------------
And to make the Coin Selection flow cleared, have decoupled SelectCoins in two functions:
1) AutomaticCoinSelection.
2) SelectCoins.
1) AutomaticCoinSelection:
Receives a set of coins and selects the best subset of them to
cover the target amount.
2) SelectCoins
In charge of select all the user manually selected coins first ("pre-set inputs"), and
if coin_control 'm_allow_other_inputs=true', call 'AutomaticCoinSelection' to select a
subset of coins owned by the wallet to cover for the target - preset_inputs.total_amount
remaining value.
First step towards decoupling the pre-selected-inputs fetching functionality
from `SelectCoins`. Which, will let us not waste resources calculating the
available coins if one of the pre-set inputs has an error.
(right now, if one of the pre-set inputs is invalid, we first walk through
the entire wallet txes map just to end up failing right after it finish)
No need to walk through the entire wallet's txes map just to get
coins that we could have gotten by just doing a simple map.find(out.hash).
(Which is what we are doing inside `SelectCoins` anyway)
no need to waste resources calculating the wallet available coins if
they are not going to be used.
The 'm_allow_other_inputs=true` default value change is to correct
an ugly misleading behavior:
The tx creation process was having a workaround patch to automatically
fall back to select coins from the wallet if `m_allow_other_inputs=false`
(previous default value) and no manual inputs were selected.
This could be seen in master in flows like `sendtoaddress`, `sendmany`
and even the GUI, where the `m_allow_other_inputs` value isn't customized
and the wallet still selects and adds coins to the tx internally.
5826bf546e test: Add test for getblockfrompeer on syncing pruned nodes (Fabian Jahr)
7fa851fba8 rpc: Pruned nodes can not fetch unsynced blocks (Fabian Jahr)
Pull request description:
This PR prevents `getblockfrompeer` from getting used on blocks that the node has not synced past yet if the node is in running in prune mode.
### Problem
While a node is still catching up to the tip that it is aware of via the headers, the user can currently use to fetch blocks close to or at the tip. These blocks are stored in the block/rev file that otherwise contains blocks the node is receiving as part of the syncing process.
This creates a problem for pruned nodes: The files containing a fetched block are not pruned during syncing because they contain a block close to the tip. This means the entire file (~130MB) will not be pruned until the tip has moved on far enough from the fetched block. In extreme cases with heavy pruning (like 550) and multiple blocks being fetched this could mean that the disc usage far exceeds what the user expects, potentially running out of space.
### Approach
There would be certainly other approaches that could fix the problem while still allowing the current behavior, but all of the ideas I came up with seemed like overkill for a niche problem on a new RPC where it's still unclear how and how much it will be used.
### Testing
So far I did not see a simple enough way to test this I am still looking into it and if it's complex will potentially add it in a follow-up. What would be needed is a way to have a node fetch headers but not sync the blocks yet, that seems like a pattern that could be generally useful.
To manually reproduce the problematic behavior:
1. Start a node with current `master` with `-prune=550` and an empty/new datadir, Testnet and Mainnet should both work.
2. While the node is syncing run `getblockfrompeer` on the current tip and a few other recent blocks.
3. Go to your datadir and observe the blocks folder: There should be a few full `blk*.dat` and `rev*.dat` files that are not being pruned. When you "pinned" a few of these files the blocks folder should be significantly above the target size of 550MB.

Pull request description:
## Description
This PR is another take of using BIP 157 block filters (enabled by `-blockfilterindex=1`) for faster wallet rescans and is a modern revival of #15845. For reviewers new to this topic I can highly recommend to read the corresponding PR review club (https://bitcoincore.reviews/15845).
The basic idea is to skip blocks for deeper inspection (i.e. looking at every single tx for matches) if our block filter doesn't match any of the block's spent or created UTXOs are relevant for our wallet. Note that there can be false-positives (see https://bitcoincore.reviews/15845#l-199 for a PR review club discussion about false-positive rates), but no false-negatives, i.e. it is safe to skip blocks if the filter doesn't match; if the filter *does* match even though there are no wallet-relevant txs in the block, no harm is done, only a little more time is spent extra.
In contrast to #15845, this solution only supports descriptor wallets, which are way more widespread now than back in the time >3 years ago. With that approach, we don't have to ever derive the relevant scriptPubKeys ourselves from keys before populating the filter, and can instead shift the full responsibility to that to the `DescriptorScriptPubKeyMan` which already takes care of that automatically. Compared to legacy wallets, the `IsMine` logic for descriptor wallets is as trivial as checking if a scriptPubKey is included in the ScriptPubKeyMan's set of scriptPubKeys (`m_map_script_pub_keys`): e191fac4f3/src/wallet/scriptpubkeyman.cpp (L1703-L1710)
One of the unaddressed issues of #15845 was that [the filter was only created once outside the loop](https://github.com/bitcoin/bitcoin/pull/15845#discussion_r343265997) and as such didn't take into account possible top-ups that have happened. This is solved here by keeping a state of ranged `DescriptorScriptPubKeyMan`'s descriptor end ranges and check at each iteration whether that range has increased since last time. If yes, we update the filter with all scriptPubKeys that have been added since the last filter update with a range index equal or higher than the last end range. Note that finding new scriptPubKeys could be made more efficient than linearly iterating through the whole `m_script_pub_keys` map (e.g. by introducing a bidirectional map), but this would mean introducing additional complexity and state and it's probably not worth it at this time, considering that the performance gain is already significant.
Output scripts from non-ranged `DescriptorScriptPubKeyMan`s (i.e. ones with a fixed set of output scripts that is never extended) are added only once when the filter is created first.

Obviously, the speed-up indirectly correlates with the wallet tx frequency in the scanned range: the more blocks contain wallet-related transactions, the less blocks can be skipped due to block filter detection.
In a [simple benchmark](https://github.com/theStack/bitcoin/blob/fast_rescan_functional_test_benchmark/test/functional/pr25957_benchmark.py), a regtest chain with 1008 blocks (corresponding to 1 week) is mined with 20000 scriptPubKeys contained (25 txs * 800 outputs) each. The blocks each have a weight of ~2500000 WUs and hence are about 62.5% full. A global constant `WALLET_TX_BLOCK_FREQUENCY` defines how often wallet-related txs are included in a block. The created descriptor wallet (default setting of `keypool=1000`, we have 8*1000 = 8000 scriptPubKeys at the start) is backuped via the `backupwallet` RPC before the mining starts and imported via `restorewallet` RPC after. The measured time for taking this import process (which involves a rescan) once with block filters (`-blockfilterindex=1`) and once without block filters (`-blockfilterindex=0`) yield the relevant result numbers for the benchmark.
The following table lists the results, sorted from worst-case (all blocks contain wallte-relevant txs, 0% can be skipped) to best-case (no blocks contain walltet-relevant txs, 100% can be skipped) where the frequencies have been picked arbitrarily:
wallet-related tx frequency; 1 tx per... | ratio of irrelevant blocks | w/o filters | with filters | speed gain
--------------------------------------------|-----------------------------|-------------|--------------|-------------
~ 10 minutes (every block) | 0% | 56.806s | 63.554s | ~0.9x
~ 20 minutes (every 2nd block) | 50% (1/2) | 58.896s | 36.076s | ~1.6x
~ 30 minutes (every 3rd block) | 66.67% (2/3) | 56.781s | 25.430s | ~2.2x
~ 1 hour (every 6th block) | 83.33% (5/6) | 58.193s | 15.786s | ~3.7x
~ 6 hours (every 36th block) | 97.22% (35/36) | 57.500s | 6.935s | ~8.3x
~ 1 day (every 144th block) | 99.31% (143/144) | 68.881s | 6.107s | ~11.3x
(no txs) | 100% | 58.529s | 5.630s | ~10.4x
Since even the (rather unrealistic) worst-case scenario of having wallet-related txs in _every_ block of the rescan range obviously doesn't take significantly longer, I'd argue it's reasonable to always take advantage of block filters if they are available and there's no need to provide an option for the user.
Feedback about the general approach (but also about details like naming, where I struggled a lot) would be greatly appreciated. Thanks fly out to furszy for discussing this subject and patiently answering basic question about descriptor wallets!

Pull request description:
It seems preferable to assign globals to a class (in this case `ChainstateManager`), than to leave them dangling. This should clarify scope for code-readers, as well as clarifying unit test behaviour.

9153ff3e27 rpc: add non-regression test about deriveaddresses crash when index is 2147483647 (muxator)
addf9d6502 rpc: fix crash in deriveaddresses when derivation index is 2147483647 (muxator)
Pull request description:
This PR is a proposal for fixing #26274 (better described there).
The problem is due to a signed int wrapping when the `index` parameter of the `deriveaddresses` RPC call has the value `2^31-1`.
```C++
for (int i = range_begin; i <= range_end; ++i) {
```
* the first commit adds a "temporary" test case (`test/functional/rpc_deriveaddresses_crash.py`) that shows the crash, and can be used to generate a core dump;
* the second commit fixes the problem giving an explicit size to the `i` variable in a for loop, from `int` to `int64_t`. The same commit also removes the ephemeral test case and adds a passing test to `test/functional/rpc_deriveaddresses.py`, in order to prevent future regressions.
This is my first submission to this project and I do not know its conventions. Please advise if something needs to be changed.

796b020c37 wallet: add taproot support to external signer (Sjors Provoost)
Pull request description:
Builds on #22558 (merged on 2022-06-28).
[HWI 2.1.0](https://github.com/bitcoin-core/HWI/releases/tag/2.1.0) or newer is required to import and use taproot descriptors. Older versions will work, but won't import a taproot descriptor.
Tested with HWI 2.1.1:
* Trezor T (firmware v2.5.1) on Signet: signs, change detection works
* Ledger Nano S (firmware 2.1.0, Bitcoin app 2.0.6): signs, change detection works
Only the most basic `tr(key)` descriptor is supported, script path spending is completely untested (if it works at all).
