In the wallet key-value-loading routine, most legacy type entries
require a LegacyScriptPubKeyMan instance after successful
deserialization. On a descriptor wallet, creating that (via method
`GetOrCreateLegacyScriptPubKeyMan`) fails and then leads to a
null-pointer dereference crash. Fix this by throwing an error if
if the wallet flags indicate that we have a descriptor wallet and there
is a legacy entry found.
It's nice to be able to use named options and positional arguments together.
Most shell tools accept both, and python functions combine options and
arguments allowing them to be passed with even more flexibility. This change
adds support for python's approach so as a motivating example:
bitcoin-cli -named createwallet wallet_name=mywallet load_on_startup=1
Can be shortened to:
bitcoin-cli -named createwallet mywallet load_on_startup=1
JSON-RPC standard doesn't have a convention for passing named and positional
parameters together, so this implementation makes one up and interprets any
unused "args" named parameter as a positional parameter array.
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.

Pull request description:
Seems odd to reserve memory for the struct (the heaviest member being `m_tx_inventory_known_filter`) when it is never used.
This also avoids sending out `msg_sendtxrcncl` before disconnecting. This shouldn't matter, as other messages, such as `msg_wtxidrelay`, `msg_sendaddrv2`, `msg_verack` or `msg_getaddr` are still sent. Though, it allows to test the changes here as a side-effect.

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