Replace calls to AsBytePtr with direct calls to AsBytes or reinterpret_cast.
AsBytePtr is just a wrapper around reinterpret_cast. It accepts any type of
pointer as an argument and uses reinterpret_cast to cast the argument to a
std::byte pointer.
Despite taking any type of pointer as an argument, it is not useful to call
AsBytePtr on most types of pointers, because byte representations of most types
will be implmentation-specific. Also, because it is named similarly to the
AsBytes function, AsBytePtr looks safer than it actually is. Both AsBytes and
AsBytePtr call reinterpret_cast internally and may be unsafe to use with
certain types, but AsBytes at least has some type checking and can only be
called on Span objects, while AsBytePtr can be called on any pointer argument.

941b8c6539d72890fd4e36fc900be9c300e1d737 [bug] Increase SRD target by change_fee (Murch)
Pull request description:
I discovered via fuzzing of another coin selection approach that at extremely high feerates SRD may find input sets that lead to transactions without change outputs. This is an unintended outcome since SRD is meant to always produce a transaction with a change output—we use other algorithms to specifically search for changeless solutions.
The issue occurs when the flat allowance of 50,000 ṩ for change is insufficient to pay for the creation of a change output with a non-dust amount, at and above 1,613 ṩ/vB. Increasing the change budget by `change_fee` makes SRD behave as expected at any feerates.
Note: The intermittent failures of `test/functional/interface_usdt_mempool.py` are a known issue: https://github.com/bitcoin/bitcoin/issues/27380

Pull request description:
One of the goals of https://github.com/bitcoin/bitcoin/pull/27783 was to get rid of the `BOOST_ASSERT` macros instead of including the `boost/assert.hpp` headers. See https://github.com/bitcoin/bitcoin/pull/27783#discussion_r1210612717.
It turns out that a couple of those macros sneaked into the codebase in https://github.com/bitcoin/bitcoin/pull/27790.
This PR makes the linter guard against new instances of the `BOOST_ASSERT` macros and replaces the current ones.

40b333e21f8741e2f553df6b5dcff7277c00a982 fuzz: wallet, add target for CoinControl (Ayush Singh)
Pull request description:
This PR adds fuzz coverage for `wallet/coincontrol`.
Motivation: Issue [#27272](https://github.com/bitcoin/bitcoin/issues/27272#issue-1628327906)
The idea is to create different/unique instances of `COutPoint` by placing it inside the `CallOneOf` function, which may or may not be consumed by all of the `CoinControl` file's methods.
This is my first PR on Bitcoin Core, and I will try my best to address any reviews/changes ASAP. I'm also working on fuzz harness files for other files in the wallet and plan to open PR for them soon.

Pull request description:
The `blank` wallet flag is used to indicate that the wallet intentionally does not have any keys, scripts, or descriptors, and it prevents the automatic generation of those things for such a wallet. Once the wallet contains any of those data, it is unnecessary, and possibly incorrect, to have `blank` set. This PR fixes a few places where this was not properly happening. It also adds a test for this unset behavior.

In order to get records beginning with a prefix, we will need a cursor
specifically for that prefix. So add a GetPrefixCursor function and
DatabaseCursor classes for dealing with those prefixes.
Tested on each supported db engine.
1) Write two different key->value elements to db.
2) Create a new prefix cursor and walk-through every returned element,
verifying that it gets parsed properly.
3) Try to move the cursor outside the filtered range: expect failure
and flag complete=true.

As the fuzzer test requires all blocks to be
scanned by the wallet (because it is asserting
the wallet balance at the end), we need to
ensure that no blocks are skipped by the recently
added wallet birth time functionality.
This just means setting the chain accumulated time
to the maximum value, so the wallet birth time is
always below it, and the block is always processed.

Pull request description:
I have a few PRs and branches that use these two commits, probably makes sense to split them into a separate PR to be merged sooner.
The first commit contains some things that end up being commonly used in new wallet benchmarks. These are moved into `wallet_common.{h/cpp}`.
The second commit contains a bugfix for the wallet_balance benchmark where it calls `LoadWallet` in the wrong place. It's unnecessary to call that function in this benchmark. Although this does not cause any issues currently, it ends up causing issues in some PRs and branches that I'm working on.

Pull request description:
This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/27587https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel".
---
It removes the kernel library's dependency on `util/system` and `interface_ui`. `util/system` contains networking and shell-related code that should not be part of the kernel library. The following pull requests prepared `util/system` for this final step: https://github.com/bitcoin/bitcoin/pull/27419https://github.com/bitcoin/bitcoin/pull/27254https://github.com/bitcoin/bitcoin/pull/27238.
`interface_ui` defines functions for a more general node interface and has a dependency on `boost/signals2`. After applying the patches from this pull request, the kernel's reliance on boost is down to `boost::multiindex`.
The approach implemented here introduces some indirection, which makes the code a bit harder to read. Any suggestions for improving or reworking this pull request to make it more concise, or even reworking it into a more proper interface, are appreciated.

096487c4dcfadebe5ca959927f5426cae1c304d5 wallet: introduce generic recursive tx state updating function (ishaanam)
Pull request description:
This implements a fix for #7315. Previously when a block was disconnected any transactions that were conflicting with transactions mined in that block were not updated to be marked as inactive. The fix implemented here is described on the [Bitcoin DevWiki](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking#idea-refresh-conflicted). A test which tested the previous behavior has also been updated.
Second attempt at #17543

The wallet tests and benchmarks both had helper functions for loading
and unloading the wallet for the test that were almost identical.
These functions are consolidated and reused.
To avoid wasting processing power, we can skip blocks that occurred
before the wallet's creation time, since these blocks are guaranteed
not to contain any relevant wallet data.
This has direct implications (an speed improvement) on the underlying
blockchain synchronization process as well.
The reason is that the validation interface queue is limited to
10 tasks per time. This means that no more than 10 blocks can be
waiting for the wallet(s) to be processed while we are synchronizing
the chain (activating the best chain to be more precise).
Which can be a bottleneck if blocks arrive and are processed faster
from the network than what they are processed by the wallet(s).
Since the kernel library no longer depends on the system file, move it
to the common library instead in accordance to the diagram in
doc/design/libraries.md.

Pull request description:
Decoupled from #26644 so it can closed in favor of #26715.
Basically, with bdb, we can't make a write operation while we are traversing the db with the same db handler. These two operations are performed in different txn contexts and cause a deadlock.
Added coverage by using `EraseRecords()` which is the simplest function that executes this process.
To replicate it, need bdb support and drop the first commit. The test will run forever.
