We currently return "Insufficient funds" which doesn't really
describe what went wrong; the tx creation failed because of
a long-mempool-chain, not because of a lack of funds.
Also, return early from Coin Selection if the sum of the
discarded coins decreases the available balance below the
target amount.

Pull request description:
The idea originates from https://github.com/bitcoin/bitcoin/pull/24845#issuecomment-1130310321.
Note:
For clarity, it's recommended to start reviewing from the end result to understand the structure of the flow.
#### GroupOutputs function rationale:
If "Avoid Partial Spends" is enabled, the function gathers outputs with the same script together inside a container. So Coin Selection can treats them as if them were just one possible input and either select them all or not select them.
#### How the Inputs Fetch + Selection process roughly works:
```
1. Fetch user’s manually selected inputs.
2. Fetch wallet available coins (walks through the entire wallet txes map) and insert them into a set of vectors (each vector store outputs from a single type).
3. Coin Selection Process:
Call `AttemptSelection` 8 times. Each of them expands the coin eligibility filter (accepting a larger subset of coins in the calculation) until it founds a solutions or completely fails if no solutions gets founds after the 8 rounds.
Each `AttemptSelection` call performs the following actions:
- For each output type supported by the wallet (P2SH, P2PK, P2WPKH, P2WSH and a combination of all of them):
Call ‘ChooseSelectionResult’ providing the respective, filtered by type, coins vector. Which:
I. Groups the outputs vector twice (one for positive only and a second one who includes the negative ones as well).
- GroupOutputs walks-through the entire inputted coins vector one time at least, + more if we are avoiding partial spends, to generate a vector of OutputGroups.
II. Then performs every coin selection algorithm using the recently created vector of OutputGroup: (1) BnB, (2) knapsack and (3) SRD.
III. Then returns the best solution out of them.
```
We perform the general operation of gathering outputs, with the same script, into a single container inside:
Each coins selection attempt (8 times —> each coin eligibility filter), for each of the outputs vector who were filtered by type (plus another one joining all the outputs as well if needed), twice (one for the positive only outputs effective value and a second one for all of them).
So, in the worst case scenario where no solution is found after the 8 Coin Selection attempts, the `GroupOutputs` function is called 80 times (8 * 5 * 2).
#### Improvements:
This proposal streamlines the process so that the output groups, filtered by coin eligibility and type, are created in a single loop outside of the Coin Selection Process.
The new process is as follows:
```
1. Fetch user’s manually selected inputs.
2. Fetch wallet available coins.
3. Group outputs by each coin eligibility filter and each different output type found.
4. Coin Selection Process:
Call AttemptSelection 8 times. Each of them expands the coin eligibility filter (accepting different output groups) until it founds a solutions or completely fails if no solutions gets founds after the 8 rounds.
Each ‘AttemptSelection’ call performs the following actions:
- For each output type supported by the wallet (P2SH, P2PK, P2WPKH, P2WSH and all of them):
A. Call ‘ChooseSelectionResult’ providing the respective, filtered by type, output group. Which:
I. Performs every coin selection algorithm using the provided vector of OutputGroup: (1) BnB, (2) knapsack and (3) SRD.
II. Then returns the best solution out of them.
```
Extra Note:
The next steps after this PR will be to:
1) Merge `AvailableCoins` and `GroupOutputs` processes.
2) Skip entire coin selection rounds if no new coins are added into the subsequent round.
3) Remove global feerates from the OutputGroup class.
4) Remove secondary "grouped" tx creation from `CreateTransactionInternal` by running Coin Selection results over the aps grouped outputs vs non-aps ones.

4163093d6374e865dc57e33dbea0e7e359062e0a wallet: use Mutex for g_sqlite_mutex instead of GlobalMutex (Vasil Dimov)
Pull request description:
Using `Mutex` provides stronger guarantee than `GlobalMutex` wrt Clang's
thread safety analysis. Thus it is better to reduce the usage of
`GlobalMutex` in favor of `Mutex`.
Using `Mutex` for `g_sqlite_mutex` is ok because its usage is limited in
`wallet/sqlite.cpp` and it does not require propagating the negative
annotations to not relevant code.

Optimizes coin selection by performing the "group outputs"
procedure only once, outside the "attempt selection" process.
Avoiding the repeated execution of the 'GroupOutputs' operation
that occurs on each coin eligibility filters (up to 8 of them);
then for every coin vector type plus one for all the coins together.
This also let us not perform coin selection over coin eligibility
filtered groups that don't add new elements.
(because, if the previous round failed, and the subsequent one has
the same coins, then this new round will fail again).
The 'GroupOutputs()' function performs the same
calculations for only-positive and mixed groups,
the only difference is that when we look for
only-positive groups, we discard negative utxos.
So, instead of wasting resources calling GroupOutputs()
for positive-only first, then call it again to include
the negative ones in the result, we can execute
GroupOutputs() only once, including in the response
both group types (positive-only and mixed).
The following scenarios are covered:
1) 10 UTXO with the same script:
partial spends is enabled --> outputs must not be grouped.
2) 10 UTXO with the same script:
partial spends disabled --> outputs must be grouped.
3) 20 UTXO, 10 one from scriptA + 10 from scriptB:
a) if partial spends is enabled --> outputs must not be grouped.
b) if partial spends is not enabled --> 2 output groups expected (one per script).
3) Try to add a negative output (value - fee < 0):
a) if "positive_only" is enabled --> negative output must be skipped.
b) if "positive_only" is disabled --> negative output must be added.
4) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"not mine" UTXOs) --> it must not be added to any group
5) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"mine" UTXOs) --> it must not be added to any group
6) Surpass the 'OUTPUT_GROUP_MAX_ENTRIES' size and verify that a second partial
group gets created.
8847ce44e0713350a6d3524f62eaeb10ba548bae util: add missing include and fix function signature (Cory Fields)
Pull request description:
ping hebasto
Discovered while testing pre-compiled header support with CMake: https://github.com/theuni/bitcoin/commits/cmake-pch-poc. Compilation of that branch fails without this fix and succeeds with it.
Similar to the fix in #27144.
The problem of having a default argument in the definition was masked by the missing include. Using PCH forces that include, so we end up with the compiler error we should've been getting all along.

And not hide it inside the `OutputGroup::Insert` method.
This method does not return anything if insertion fails.
We can know before calling `Insert` whether the coin
will be accepted or not.

1d02e599012721549d4c20b1b37fcc5ee7b961b6 test: add cases to JSON parsing (stickies-v)
Pull request description:
Inspired by MarcoFalke's [comment](https://github.com/bitcoin/bitcoin/pull/26506#discussion_r1036149426). Main purpose of this PR is to minimize copying (potentially large) RPC named arguments when calling `.substr()` by using `std::string_view` instead of `std::string`. Furthermore, cleans up the code by removing unnecessary complexity in `ParseNonRFCJSONValue()` (done first to avoid refactoring required to concatenate `string` and `string_view`), updates some naming and adds a few test cases. Should not introduce any behaviour change.
## Questions
- ~Was there actually any merit to `ParseNonRFCJSONValue()` surrounding the value with brackets and then parsing it as an array? I don't see it, and the new approach doesn't fail any tests. Still a bit suspicious about it though.~
- Cleared up by https://github.com/bitcoin/bitcoin/pull/26506#pullrequestreview-1211984059
- If there are no objections to 7727603e44f8f674e0fc8389e78047e2b56e6052, I think we should follow up with a PR to rename `ParseNonRFCJSONValue()` to a local `Parse()` helper function (that throws if invalid), remove it from `client.h` and merge the test coverage we currently have on `ParseNonRFCJSONValue()` with the coverage we have on `UniValue::read()`.

Pull request description:
This adds a number of improvements to the miniscript fuzzers that all amount to rejecting invalid or overly big miniscripts early on:
* Base type propagation in the miniscript_stable fuzzers prevents constructing a large portion of miniscripts that would be illegal, with just a little bit of type logic in the fuzzer. The fuzzer input format is unchanged.
* Ops and script size tracking in GenNode means that too-large scripts (either due to script size limit or ops limit) will be detected on the fly during fuzz input processing, before actually constructing the scripts.
Closes#27147.

Pull request description:
This PR is follow up for bitcoin/bitcoin#22677 and bitcoin/bitcoin#23683.
On master (013daed9acca1b723f599d63ab36b9c2a5c60e5f) it is not obvious that `CheckSequenceLocksAtTip()` function can modify its `LockPoints* lp` parameter which leads to https://github.com/bitcoin/bitcoin/pull/22677#discussion_r762040101.
This PR:
- separates the lockpoint calculate logic from `CheckSequenceLocksAtTip()` function into a new `CalculateLockPointsAtTip()` one
- cleans up the `CheckSequenceLocksAtTip()` function interface
- makes code easier to reason about (hopefully)

fb0dbe94233ec509570cbba3118cf62d8e60842b docs: GetDataDirNet and GetDataDirBase don't create datadir (stickies-v)
Pull request description:
Since #27073, the behaviour of `GetDataDir()` [changed](https://github.com/bitcoin/bitcoin/pull/27073/files#diff-19427b0dd1a791adc728c82e88f267751ba4f1c751e19262cac03cccd2822216L435-L443) to only return the datadir path, but not create it if non-existent. This also changed the behaviour of `GetDataDirNet()` and `GetDataDirBase()` but the docs do not yet reflect that.

77557dda4a123515d0fa2a545ee21d7c43a66988 prune: scan and unlink already pruned block files on startup (Andrew Toth)
Pull request description:
There are a few cases where we can mark a block and undo file as pruned in our block index, but not actually remove the files from disk.
1. If we call `FindFilesToPrune` or `FindFilesToPruneManual` and crash before `UnlinkPrunedFiles`.
2. If on Windows there is an open file handle to the file somewhere else when calling `fs::remove` in `UnlinkPrunedFiles` (https://en.cppreference.com/w/cpp/filesystem/remove, https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-deletefilew#remarks). This could be from another process, or if we are calling `ReadBlockFromDisk`/`ReadRawBlockFromDisk` without having a lock on `cs_main` (which has been allowed since ccd8ef65f9).
This PR mitigates this by scanning all pruned block files on startup after `LoadBlockIndexDB` and unlinking them again.

Use the same technique as is using in the FromString miniscript parser to
predict the final script size of the miniscript being generated in the
miniscript_stable and miniscript_smart fuzzers (by counting every unexplored
sub node as 1 script byte, which is possible because every leaf node always
adds at least 1 byte). This allows bailing out early if the script being
generated would exceed the maximum allowed size (before actually constructing
the miniscript, as that may happen only significantly later potentially).
Also add a self-check to make sure this predicted script size matches that
of generated scripts.
Keep track of the total number of ops the constructed script will have
during miniscript_stable and miniscript_smart fuzzers' GenNode, so it
can abort early if the 201 ops limit would be exceeded.
Also add a self-check that the final constructed node has the predicted
ops size limit, so we know the fuzzer's logic for keeping track of this
is correct.
Since we now keep track of all expected child node types (even if rudimentary)
in both miniscript_stable and miniscript_smart fuzzers, there is no need anymore
for the former shortcut NodeInfo constructors without sub types.
Keep track of which base type (B, K, V, or W) is desired in the miniscript_stable
ConsumeStableNode function. This allows aborting early if the constructed node
won't have the right type.
Note that this does not change the fuzzer format; the meaning of inputs in
ConsumeStableNode is unmodified. The only change is that often the fuzzer will
abort early.
The direct motivation is preventing recursing v: wrappers, which are the only
fragment type that does not otherwise increase the overall minimum possible script
size. In a later commit this will be exploited to prevent overly-large scripts from
being constructed.
Since #27073, the behaviour of GetDataDir changed to only return
the datadir path, but not create it. This also changed the behaviour
of GetDataDirNet and GetDataDirBase but the docs do not yet reflect
that.

7dff7da4f5eafa89546565a63362e57516e4064e init: Return more fitting ChainStateLoadStatus if verification was interrupted (Martin Zumsande)
Pull request description:
This addresses two outstanding comments by ryanofsky from #25574:
* return `ChainstateLoadStatus::INTERRUPTED` instead of `ChainstateLoadStatus::SUCCESS` if verification was stopped by an interrupt. This would coincide with straightforward expectation, and it avoids a misleading [log entry](c5825e14f8/src/init.cpp (L1526)) in `init` for the block index load time (because that would include the verificiation, which didn't complete). It shouldn't affect node behavior otherwise because the shutdown signal would be caught in init anyway. In test, this would lead to an assert ([link](c5825e14f8/src/test/util/setup_common.cpp (L230))), which also makes more sense because benign interrupts are not expected there during init.
This can be tested by setting a large value for `-checkblocks`, interrupting the node during block verification and observing the log.

Most of the code in util/system.cpp that was hardcoded to use the global
ArgsManager instance `gArgs` has been changed to work with explicit ArgsManager
instances (for example in https://github.com/bitcoin/bitcoin/pull/20092). But a
few hardcoded references to `gArgs` remain. This commit removes the last ones
so these functions aren't reading or writing global state.
New function was introduced by willcl-ark <will@256k1.dev> in commit
56e370fbb9413260723c598048392219b1055ad0 from

807de2cebdad960c2b52185528ca8960ec694f49 wallet: skip R-value grinding for external signers (Sjors Provoost)
72b763e4521e674990da5dd1999b7a8c7bd3ba8c wallet: annotate bools in descriptor SPKM FillPSBT() (Sjors Provoost)
Pull request description:
When producing a dummy signature for the purpose of estimating the transaction fee, do not assume an external signer performs R-value grinding on the signature.
In particular, this avoids a scenario where the fee rate is 1 sat / vbyte and a transaction with a 72 byte signature is not accepted into our mempool.
Suggested testing:
1. On master, launch with `-signet` and create an external signer wallet using e.g. a Trezor and HWI, see [guide](https://github.com/bitcoin/bitcoin/blob/master/doc/external-signer.md#example-usage) (with the GUI it should "just work" once you have the HWI path configured).
2. Create a few addresses and fund them from the faucet: https://signet.bc-2.jp/ (wait for confirmation)
3. Create another address, and now send the entire wallet to it, set the fee to 1 sat/byte
4. Most likely this transaction never gets broadcast and you won't see it on the [signet explorer](https://explorer.bc-2.jp)
5. With this PR, try again.
6. Check the explorer and inspect the transaction. Each input witness starts with either `30440220` (R has 32 bytes) or `30440221` (R has 33 bytes). See this explainer for [DER encoding](https://bitcoin.stackexchange.com/questions/92680/what-are-the-der-signature-and-sec-format).
