Pull request description:
This PR taken over from #29264
The PR added an option `max_tx_weight` to transaction funding RPC's that ensures the resulting transaction weight does not exceed the specified `max_tx_weight` limit.
If `max_tx_weight` is not given `MAX_STANDARD_TX_WEIGHT` is used as the max threshold.
This PR addressed outstanding review comments in #29264

Fix cases of calls to `FillPSBT` returning `complete=true` when it's not
the case.
This can happen when some inputs have been signed but the transaction is
subsequently modified, e.g. in the context of PayJoins.
Also fixes a related bug where a finalized hex string is attempted to be
added during `walletprocesspsbt` but a CHECK_NONFATAL causes an abort.

Pull request description:
Prior to C++20, `modernize-use-equals-default` could have been problematic because it could turn a non-aggregate into an aggregate. The risk would be that aggregate initialization would be enabled where the author did not intend to enable it.
With C++20, aggregate for those is forbidden either way. (https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p1008r1.pdf)
So enabled it for code clarity, consistency, and possibly unlocking compiler optimizations. See https://clang.llvm.org/extra/clang-tidy/checks/modernize/use-equals-default.html

In SetupLegacyScriptPubKeyMan, a base LegacyDataSPKM will be created if
the database has the format "bdb_ro" (i.e. the wallet was opened only
for migration purposes).
All of the loading functions are now called with a LegacyDataSPKM object
instead of LegacyScriptPubKeyMan.
In order to load the necessary data for migrating a legacy wallet
without the full LegacyScriptPubKeyMan, move the data storage and
loading components to LegacyDataSPKM. LegacyScriptPubKeyMan now
subclasses that.

adc6ab25bba42ce9e7ed6bd7599aabb6dead6987 wallet: use CRecipient instead of CTxOut (josibake)
Pull request description:
Broken out from #28201
---
In order to estimate fees properly, we need to know what the final serialized transaction size will be. This PR refactors `CreateTransactionInternal` to:
* Get the serialized size directly from the `CRecipient`: this sets us up in a future PR to calculate the serialized size of silent payment `CTxDestinations` (see 797e21c8c1)
* Use the new `GetSerializeSizeForRecipient` to move the serialize size calculation to *before* coin selection and the output creation to *after* coin selection: this also sets us up for silent payments sending in a future PR in that silent payments outputs cannot be created until after the inputs to the transaction have been selected
Aside from the silent payments use case, I think this structure logically makes more sense. As a reminder, move-only commits are best reviewed with something like `git diff -w --color-moved=dimmed-zebra`

This allows a transaction's weight to be bound under a certain
weight if possible and desired. This can be beneficial for future
RBF attempts, or whenever a more restricted spend topology is
desired.

- This change ensures consistency in transaction size and weight calculation
within the wallet and prevents conversion overflow when calculating
`max_selection_weight`.
`CoinGrinder` will also produce change output, listing all the
Coin selection algorithms that produces change output is not maintainable,
just infer that remaining algorithms all might produce change.
- This commit renames the coin selection algorithms input parameter `max_weight`
to `max_selection_weight` for clarity.
The parameter represent the maximum weight of the UTXOs the coin selection algorithm
should select, not the transaction maximum weight.
- The commit updates the parameter docstring to provide correct description.
- Also updates coin selection unit and fuzzing test variables to match the new name.
72b226882fe2348a9a66aee1d8d21b4e2d275e68 wallet: notify when preset + automatic inputs exceed max weight (furszy)
Pull request description:
Small change. Found it while finishing my review on #29523. This does not interfere with it.
Basically, we are erroring out early when the automatic coin selection process exceeds the maximum weight, but we are not doing so when the user-preselected inputs combined with the wallet-selected inputs exceed the maximum weight.
This change avoids signing all inputs before erroring out and introduces test coverage for `fundrawtransaction`.

Move the output serialization size and dust calculation into the loop where the
outputs are iterated over to calculate the total sum.
Move the code for adding the the txoutputs to the transaction to after
coin selection.
While this code structure generally follows a more logical flow,
the primary motivation for moving the code for adding outputs to the
transaction sets us up nicely for silent payments (in a future PR):
we need to know the input set before generating the final output scriptPubKeys.
Now that a CRecipient holds a CTxDestination, we can get the serialized
size and determine if the output is dust using the CRecipient directly.
This does not change any current behavior, but provides a nice generalization
that can be used to apply special logic to a CTxDestination serialization
and dust calculations in the future.
Specifically, in a later PR when support for `V0SilentPayment` destinations is
added, we need to use `WitnessV1Taproot` as the scriptPubKey for serialized
size calcuations whenever the `CRecipient` destination is a `V0SilentPayment`
destination.

436e88f4336199998184cbfa5d1c889ffaefbfb5 bumpfee: ignore WALLET_INCREMENTAL_RELAY_FEE when user specifies fee rate (ismaelsadeeq)
Pull request description:
Fixes#26973
When using the `bumpfee` RPC and manually specifying `fee_rate`, there should be no requirement that the new fee must be at least the sum of the original fee and `incrementalFee` (maximum of `relayIncrementalFee` and `WALLET_INCREMENTAL_RELAY_FEE`).
This restriction should only apply when user did not specify `fee_rate`.
> because the GUI doesn't let the user specify the new fee rate yet (https://github.com/bitcoin-core/gui/issues/647), it would be very annoying to have to bump 20 times to increment by 20 sat/vbyte.
The restriction should instead be the new fee must be at least the sum of the original fee and `incrementalFee` (`relayIncrementalFee`)

Pull request description:
Remove `fees.h`, `errors.h`, and `spanparsing.h` from the util library. Specifically:
- Move `Split` functions from `util/spanparsing.h` to `util/string.h`, using `util` namespace for clarity.
- Move remaining spanparsing functions to `script/parsing.h` since they are used for descriptor and miniscript parsing.
- Combine `util/fees.h` and `util/errors.h` into `common/messages.h` so there is a place for simple functions that generate user messages to live, and these functions are not part of the util library.
Motivation for this change is that the util library is a dependency of the kernel, and we should remove functionality from util that shouldn't be called by kernel code or kernel applications. These changes should also improve code organization and make functions easier to discover. Some of these same moves are (or were) part of #28690, but did not help with code organization, or made it worse, so it is better to move them and clean them up in the same PR so code only has to change one time.

Pull request description:
Fixing https://github.com/bitcoin/bitcoin/issues/28250#issuecomment-1674830104 and more.
Currently, redeem scripts longer than 520 bytes, which are technically valid under segwit rules, have flaws in the following processes:
1) The multisig creation process fails to deduce the output descriptor, resulting in the generation of an incorrect descriptor. Additionally, the accompanying user warning is also inaccurate.
2) The `signrawtransactionwithkey` RPC command fail to sign them.
3) The legacy wallet `addmultisigaddress` wrongly discards them.
The issue arises because most of these flows are utilizing the legacy spkm keystore, which imposes
the [p2sh max redeem script size rule](ded6873340/src/script/signingprovider.cpp (L160)) on all scripts. Which blocks segwit redeem scripts longer than
the max element size in all the previously mentioned processes (`createmultisig`, `addmultisigaddress`, and
`signrawtransactionwithkey`).
This PR fixes the problem, enabling the creation of multisig output descriptors involving more than 15 keys and
allowing the signing of these scripts, along with other post-segwit redeem scripts that surpass the 520-byte
p2sh limit.
Important note:
Instead of adding support for these longer redeem scripts in the legacy wallet, an "unsupported operation"
error has been added. The reasons behind this decision are:
1) The introduction of this feature brings about a compatibility-breaking change that requires downgrade
protection; older wallets would be unable to interact with these "new" legacy wallets.
2) Considering the ongoing deprecation of the legacy spkm, this issue provides another compelling
reason to transition towards descriptors.
Testing notes:
To easily verify each of the fixes, I decoupled the tests into standalone commits. So they can be
cherry-picked on top of master. Where `rpc_createmultisig.py` (with and without the `--legacy-wallet`
arg) will fail without the bugs fixes commits.
Extra note:
The initial commits improves the `rpc_createmultisig.py` test in many ways. I found this test very
antiquated, screaming for an update and cleanup.

Pull request description:
This PR adds fuzz coverage for `wallet/crypter`.
Motivation: Issue [27272](https://github.com/bitcoin/bitcoin/issues/27272#issue-1628327906)
I ran this for a long time with Sanitizers on and had no crashes; the average `exec/sec` also looks good to me. However, I would really appreciate it if some of the reviewers could try it on their machines too, and give their feedback.

7aa7e30441fe77bf8e8092916e36b004bbbfe2a7 Fold GetSelectionWaste() into ComputeAndSetWaste() (Murch)
Pull request description:
PR #26152 moved waste calculation into SelectionResult to be able to correct the waste score on basis of the bump_fee_group_discount for overlapping ancestries. This left two functions with largely overlapping purpose, where one was simply a wrapper of the other. This PR cleans up the overlap, and fixes the double-meaning of `change_cost` where the `GetChange()` function assumed that no change was created when `change_cost` was set to 0. This behavior was exploited in a bunch of tests, but is problematic, because a `change_cost` of 0 is permitted with custom settings for feerate and discard_feerate (i.e. when they’re both 0).

Both `GetSelectionWaste()` and `ComputeAndSetWaste()` now are part of
`SelectionResult`. Instead of `ComputeAndSetWaste()` being a wrapper for
`GetSelectionWaste()`, we combine them to a new function
`RecalculateWaste()`.
As I was combining the logic of the two functions, I noticed that
`GetSelectionWaste()` was making the odd assumption that the
`change_cost` being set to zero means that no change is created.
However, if we build transactions at a feerate of zero with the
`discard_feerate` also set to zero, we'd organically have a
`change_cost` of zero, even when we create change on a transaction.
This commit cleans up this duplicate meaning of `change_cost` and relies
on `GetChange()` to figure out whether there is change on basis of the
`min_viable_change` and whatever is left after deducting fees.
Since this broke a bunch of tests that relied on the double-meaning of
`change_cost` a bunch of tests had to be fixed.
d7707d9843b03f20d2a8c5a45d7b3db58e169e6f rpc: avoid copying into UniValue (Cory Fields)
Pull request description:
These are the simple (and hopefully obviously correct) copies that can be moves instead.
This is a follow-up from https://github.com/bitcoin/bitcoin/pull/30094#issuecomment-2108751842
As it turns out, there are hundreds of places where we copy UniValues needlessly. It should be the case that moves are always preferred over copies, so there should be no downside to these changes.
willcl-ark, however, noticed that memory usage may increase in some cases. Logically this makes no sense to me. The only plausible explanation imo is that because the moves are faster, more ops/second occur in some cases.
This list of moves was obtained by changing the function signatures of the UniValue functions to accept only rvalues, then compiling and fixing them up one by one. There still exist many places where copies are being made. These can/should be fixed up, but weren't done here for the sake of doing the easy ones first.
I ran these changes through clang-tidy with `performance-move-const-arg` and `bugprone-use-after-move` and no bugs were detected (though that's obviously not to say it can be trusted 100%).
As stated above, there are still lots of other less trivial fixups to do after these including:
- Using non-const UniValues where possible so that moves can happen
- Refactoring code in order to be able to move a UniValue without introducing a use-after-move
- Refactoring functions to accept UniValues by value rather than by const reference
