Instead of calling GetCachableAmount twice, which will result in
iterating through all the transaction txins/txouts and calling
GetDebit/GetCredit (which lock cs_wallet), just merge the filters and do
it once.

Pull request description:
Change `getheaders` messages so that we wait up to 2 minutes for a response to a prior `getheaders` message before issuing a new one.
Also change the handling of the `getheaders` message sent in response to a block INV, so that we no longer use the hashstop variable (including the hash stop will just mean that if our peer's headers chain is longer, then we won't learn
it, so there's no benefit to using hashstop).
Also, now respond to a `getheaders` during IBD with an empty headers message (rather than nothing) -- this better conforms to the intent of the new logic that it's better to not ignore a peer's `getheaders` message, even if you have nothing to give. This also avoids a lot of functional tests breaking.
This PR also reworks the headers processing logic to make it more readable.

27c8056885 rpc: Disallow gettxoutsetinfo queries for a specific block with use_index=false (Martin Zumsande)
Pull request description:
In the `gettxoutsetinfo` RPC, if we set `use_index` to false but specify `hash_or_height`, we currently hit a nonfatal error, e.g. `gettxoutsetinfo "muhash" "1" "false"` results in:
```
Internal bug detected: "!pindex || pindex->GetBlockHash() == view->GetBestBlock()"
rpc/blockchain.cpp:836 (GetUTXOStats)
```
The failing check was added in [#24410](664a14ba7c), but the previous behavior, returning the specified height together with data corresponding to the tip's height, was very confusing too in my opinion.
Fix this by disallowing the interaction of `use_index=false` and `hash_or_height` and add a RPC help example with `-named` because users might ask themselves how to use the `use_index` flag witout hitting an error.
An alternative way would be to allow the interaction if the specified `hash_or_height` happens to correspond to the tip (which should then also be applied to the `HASH_SERIALIZED` check before). If reviewers would prefer that, please say so.

c318211ddd walletdb: fix last client version update (furszy)
bda8ebe608 wallet: don't read db every time that a new WalletBatch is created (furszy)
Pull request description:
Found it while was working on #25297.
We are performing a db read operation every time that a new `WalletBatch` is created, inside the constructor, just to check if the client version field is inside the db or not.
As the client version field does not change in the entire db lifecycle, this operation can be done only once: The first time that the db is accessed/opened and the client version value can be cached.

Since TaprootBuilder has assertions for the depth and leaf versions, the
PSBT decoder should check these values before calling
TaprootBuilder::Add so that the assertions are not triggered on
malformed taproot trees.

fa076515b0 [rpc] add new submitpackage RPC (glozow)
Pull request description:
It would be nice for LN/wallet/app devs to test out package policy, package RBF, etc., but the only interface to do so right now is through unit tests. This PR adds a `-regtest` only RPC interface so people can test by submitting raw transaction data. It is regtest-only, as it would be unsafe/confusing to create an actual mainnet interface while package relay doesn't exist.
Note that the functional tests are there to ensure the RPC interface is working properly; they aren't for testing policy itself. See src/test/txpackage_tests.cpp.

Follow-up to #617. This applies translator strings to the
reset options confirmation dialog and also refactors the way we pass the
strings to the dialog in order to allow the comments to be applied.
Because the strings were being concatenated, we can not apply translator
comments to all of the relevant strings. What we want to do instead is
have a variable in which the translatable strings are appended to using
the QString append function. This satisfies the Qt translator engine and
the comments are then properly applied within the `extracomment` field
in the translation file.

af56d63eca Revert "bnb: exit selection when best_waste is 0" (Murch)
Pull request description:
This reverts commit 9b5950db86.
Waste can be negative. At feerates lower than long_term_feerate this
means that a waste of 0 may be a suboptimal solution and this causes the
search to exit prematurely.
Only when the feerate is equal to the long_term_feerate would achieving
a waste of 0 indicate that we have achieved an optimal solution,
because it would mean that the excess is 0. It seems unlikely
that this would ever occur outside of test cases, and even then we
should prefer solutions with more inputs over solutions with fewer
according to previous decisions—but solutions with more inputs are found
later in the branch exploration.
The "optimization" described in #18257 and implemented in #18262 is
therefore a premature exit on a suboptimal solution and should be reverted.

utACK af56d63eca, agree it is incorrect to stop here unless we could rule out the possibility of a better solution with negative waste. `SelectCoinsBnB` doesn't know what long term feerate and effective feerate are (and probably shouldn't) so it's better to have no exit early condition at all.

Pull request description:
This is part of the `libbitcoinkernel` project: #24303, https://github.com/bitcoin/bitcoin/projects/18
-----
As mentioned in the Stage 1 Step 2 description of [the `libbitcoinkernel` project](https://github.com/bitcoin/bitcoin/issues/24303), `ArgsManager` will not be part of `libbitcoinkernel`. Therefore, it is important that we remove any dependence on `ArgsManager` by code that will be part of `libbitcoinkernel`. This is the first in a series of PRs aiming to achieve this.
This PR removes `CTxMemPool+MempoolAccept`'s dependency on `ArgsManager` by introducing a `CTxMemPool::Options` struct, which is used to specify `CTxMemPool`'s various options at construction time.
These options are:
- `-maxmempool` -> `CTxMemPool::Options::max_size`
- `-mempoolexpiry` -> `CTxMemPool::Options::expiry`
- `-limitancestorcount` -> `CTxMemPool::Options::limits::ancestor_count`
- `-limitancestorsize` -> `CTxMemPool::Options::limits::ancestor_size`
- `-limitdescendantcount` -> `CTxMemPool::Options::limits::descendant_count`
- `-limitdescendantsize` -> `CTxMemPool::Options::limits::descendant_size`
More context can be gleaned from the commit messages. The important commits are:
- 56eb479ded8bfb2ef635bb6f3b484f9d5952c70d "pool: Add and use MemPoolOptions, ApplyArgsManOptions"
- a1e08b70f3068f4e8def1c630d8f50cd54da7832 "mempool: Pass in -maxmempool instead of referencing gArgs"
- 6f4bf3ede5812b374828f08fc728ceded2f10024 "mempool: Pass in -mempoolexpiry instead of referencing gArgs"
- 5958a7fe4806599fc620ee8c1a881ca10fa2dd16 "mempool: Introduce (still-unused) MemPoolLimits"
Reviewers: Help needed in the following commits (see commit messages):
- a1e08b70f3068f4e8def1c630d8f50cd54da7832 "mempool: Pass in -maxmempool instead of referencing gArgs"
- 0695081a797e9a5d7787b78b0f8289dafcc6bff7 "node/ifaces: Use existing MemPoolLimits"
Note to Reviewers: There are perhaps an infinite number of ways to architect `CTxMemPool::Options`, the current one tries to keep it simple, usable, and flexible. I hope we don't spend too much time arguing over the design here since that's not the point. In the case that you're 100% certain that a different design is strictly better than this one in every regard, please show us a fully-implemented branch.
-----
TODO:
- [x] Use the more ergonomic `CTxMemPool::Options` where appropriate
- [x] Doxygen comments for `ApplyArgsManOptions`, `MemPoolOptions`
-----
Questions for Reviewers:
1. Should we use `std::chrono::seconds` for `CTxMemPool::Options::expiry` and `CTxMemPool::m_expiry` instead of an `int64_t`? Something else? (`std::chrono::hours`?)
2. Should I merge `CTxMemPool::Limits` inside `CTxMemPool::Options`?

Change getheaders messages so that we wait up to 2 minutes for a response to a

Also change the handling of the getheaders message sent in response to a block
INV, so that we no longer use the hashstop variable (including the hash stop
will just mean that if our peer's headers chain is longer, then we won't learn
it, so there's no benefit to using hashstop).
Also, now respond to a getheaders during IBD with an empty headers message

that it's better to not ignore a peer's getheaders message, even if you have
nothing to give. This also avoids a lot of functional tests breaking.
p2p_segwit.py is modified to use this same strategy, as the test logic (of
expecting a getheaders after a block inv) would otherwise be broken.
Also moves the call to happen directly after validation of a headers message
(rather than mixed in with other state updates for the peer), and removes an
incorrect comment in favor of one that explains why headers sync must continue
from the last header a peer has sent.
