Extracted existing serialization to append size & data in separate private methods to clarify that it does more than just a simple data insertion.
* the C style casts were changed to static_cast
* `unsigned char` and `uint8_t` were changed to value_type for forward compatibility
* `data + sizeof(data)` was changed to `std::cend`
* data insertion (in AppendData) relies on pointer arithmetic now to enable both `std::span<const value_type>` and `std::span<const std::byte>` operators
* use uint32_t for data size instead of size_t
* used span instead of raw pointers in the new methods

When compiling with GCC 12.2, both `-Warray-bounds` and `-Wstringop-overflow` warnings were triggered in the `prevector::insert` method during CScript prevector operations.
GCC incorrectly assumed that operator new could modify the state of class members, leading to false positives during the memmove operation.
Following the approach in https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=cca06f0d6d76b0, we introduced local copies for the destination pointer in memmove operations. This prevents GCC from misinterpreting memory manipulation as unsafe.
A minimal reproducer triggering this issue in GCC 12.2 and passing in GCC 12.3 can be found at https://godbolt.org/z/8r9TKKoxv.

Because AssumeUTXO nodes prioritize tip synchronization, they relay their local
address through the network before completing the background chain sync.
This, combined with the advertising of full-node service (NODE_NETWORK), can
result in an honest peer in IBD connecting to the AssumeUTXO node (while syncing)
and requesting an historical block the node does not have. This behavior leads to
an abrupt disconnection due to perceived unresponsiveness (lack of response)
from the AssumeUTXO node.
This lack of response occurs because nodes ignore getdata requests when they do
not have the block data available (further discussion can be found in PR 30385).
Fix this by refraining from signaling full-node service support while the
background chain is being synced. During this period, the node will only
signal 'NODE_NETWORK_LIMITED' support. Then, full-node ('NODE_NETWORK')
support will be re-enabled once the background chain sync is completed.

Pull request description:
_Continuation of #30569._
Since fad2991ba0, `uint256S()` has been [deprecated](fad2991ba0 (diff-800776e2dda39116e889839f69409571a5d397de048a141da7e4003bc099e3e2R138)) because it is less robust than the `base_blob::FromHex()` introduced in https://github.com/bitcoin/bitcoin/pull/30482. Specifically, it tries to recover from length-mismatches, recover from untrimmed whitespace, 0x-prefix and garbage at the end, instead of simply requiring exactly 64 hex-only characters. (see also https://github.com/bitcoin/bitcoin/pull/30532)
This PR removes `uint256S()` (and `uint160S()`) completely, with no non-test behaviour change.
Specifically, the main changes in this PR are:
- the (minimal) last non-test usage of `uint256S()` in `ParseHashV()` is removed without behaviour change, which can partially be verified by cherry-picking and/or modifying [this test commit](1f2b0fa86d)).
- the test usage of `uint{160,256}S()` is removed, largely replacing it with `uint{160,256}::FromHex()` where applicable, potentially modifying the test by removing non-hex characters or dropping the test entirely if removing non-hex characters makes it redundant
- the now unused `uint{160,256}S()` functions are removed completely.
- unit test coverage on converting `uint256` <-> `arith_uint256` through `UintToArith256()` and `ArithToUint256()` is beefed up, and `arith_uint256` tests are moved to `arith_uint256_tests.cpp`, removing the `uint256_tests.cpp` dependency on `uint256h`, mirroring how the code is structured.
_Note: `uint256::FromUserHex()` exists to more leniently construct uint256 from user input, allowing "0x" prefixes and too-short-input, as safer alternative to `uint256S()` where necessary._

Pull request description:
The current logic for file descriptor accounting is pretty convoluted and hard to follow. This is partially caused by the lack of documentation plus non-intuitive variable naming (which was more intuitive when fewer things were accounted for, but
hasn't aged well). This has led to this accounting being error-prone and hard to maintain (as shown in the first commit of this PR).
Redefine some of the constants, plus document what are we accounting for so this can be extended more easily

Pull request description:
Add `-ipcbind` option to `bitcoin-node` to make it listen on a unix socket and accept connections from other processes. The default socket path is `<datadir>/node.sock`, but this can be customized.
This option lets potential wallet, gui, index, and mining processes connect to the node and control it. See examples in #19460, #19461, and #30437.
Motivation for this PR, in combination with #30510, is be able to release a bitcoin core node binary that can generate block templates for a separate Stratum v2 mining service, like the one being implemented in https://github.com/Sjors/bitcoin/pull/48, that connects over IPC.
Other things to know about this PR:
- While the `-ipcbind` option lets other processes to connect to the `bitcoin-node` process, the only thing they can actually do after connecting is call methods on the [`Init`](https://github.com/bitcoin/bitcoin/blob/master/src/ipc/capnp/init.capnp#L17-L20) interface which is currently very limited and doesn't do much. But PRs [#30510](https://github.com/bitcoin/bitcoin/pull/30510), [#29409](https://github.com/bitcoin/bitcoin/pull/29409), and [#10102](https://github.com/bitcoin/bitcoin/pull/10102) expand the `Init` interface to expose mining, wallet, and gui functionality respectively.
- This PR is not needed for [#10102](https://github.com/bitcoin/bitcoin/pull/10102), which runs GUI, node, and wallet code in different processes, because [#10102](https://github.com/bitcoin/bitcoin/pull/10102) does not use unix sockets or allow outside processes to connect to existing processes. [#10102](https://github.com/bitcoin/bitcoin/pull/10102) lets parent and child processes communicate over internal socketpairs, not externally accessible sockets.

c2b779da4e refactor: Manage dumptxoutset RAII classes with std::optional (Fabian Jahr)
4b5bf335ad test: Add coverage for failing dumptxoutset behavior (Fabian Jahr)
Pull request description:
This adds a test that checks that network activity is not suspended if dumptxoutset fails in the middle of its process which is implemented with the `NetworkDisable` RAII class. I would have liked to add coverage for the `TemporaryRollback` RAII class but that seems a lot more tricky since the failure needs to happen at some point after the rollback and on the scale of our test chain here I couldn't find a way to do it yet. This was requested by pablomartin4btc here: https://github.com/bitcoin/bitcoin/pull/30808#pullrequestreview-2280450117. To test the test you can comment out the content of the destructor of `NetworkDisable`.
It also addresses the feedback by ryanofsky to use `std::optional` instead of `std::unique_ptr` for the management of the RAII object: https://github.com/bitcoin/bitcoin/pull/30808#discussion_r1744149228

ee47ca29d6 init: fix fatal error on '-wallet' negated option value (furszy)
Pull request description:
Currently, if users provide a double negated value such as '-nowallet=0' or a non-boolean
convertible value to a negated option such as '-nowallet=not_a_boolean', the initialization
process results in a fatal error, causing an unclean shutdown and displaying a poorly
descriptive error message:
"JSON value of type bool is not of expected type string." (On bitcoind. The GUI
does not display any error msg - upcoming PR -).
This PR fixes the issue by ensuring that only string values are returned in the
the "wallet" settings list, failing otherwise. It also improves the clarity of the
returned error message.
Note:
This bug was introduced in https://github.com/bitcoin/bitcoin/pull/22217. Where the `GetArgs("-wallet")` call was
replaced by `GetSettingsList("-wallet")`.

67df0dec1a test: blank rpcauth CLI interaction (tdb3)
ecc98ccff2 test: add cases for blank rpcauth (tdb3)
Pull request description:
The current `rpcauth` parsing behavior is inconsistent and unintuitive (see https://github.com/bitcoin/bitcoin/pull/29141#issuecomment-1972085251 and additional details below).
The current behavior inconsistently treats empty `rpcauth` as an error (or not) depending on the location within CLI/bitcoin.conf and the location of adjacent valid `rpcauth` params.
Empty `rpcauth` is now consistently treated as an error and prevents bitcoind from starting.
Continuation of the upforgrabs PR #29141.
### Additional details:
Current `rpcauth` behavior is nonsensical:
- If an empty `rpcauth` argument was specified as the last command line argument, it would cause all other `rpcauth` arguments to be ignored.
- If an empty `rpcauth` argument was specified on the command line followed by any nonempty `rpcauth` argument, it would cause an error.
- If an empty `rpcauth=` line was specified after non-empty rpcauth line in the config file it would cause an error.
- If an empty `rpcauth=` line in a config file was first it would cause other rpcauth entries in the config file to be ignored, unless there were `-rpcauth` command line arguments and the last one was nonempty, in which case it would cause an error.
New behavior is simple:
- If an empty rpcauth config line or command line argument is used it will cause an error

Since the move to cmake, the kernel static library that is installed
after a cmake --install build is unusable. It lacks symbols for the
internal libraries, besides those defined in the kernel library target.
This is because cmake, unlike the libtool archiver, does not combine
multiple static libraries into a single static library on installation.
This is likely an intentional design choice, since there were a bunch of
caveats to the way libtool calculated these libraries.
Fix this problem by installing all the required libraries. The user must
then link all of them along with the bitcoin kernel library.
move/formatting-only change.
These tests do not cover uint256, so move them to the appropriate
test suite. Additionally, apply clang-format suggestions.
uint160S is a test-only function, and testing input that
is not allowed in uint160::FromHex() is superfluous.
Tests that can't use uint160::FromHex() because they use input
with non-hex digit characters are
a) modified by dropping the non-hex digit characters if that
provides useful test coverage.
b) dropped if the test without non-hex digit characters does
not provide useful test coverage, e.g. because it is now
duplicated.
uint256S was previously deprecated for being unsafe. All non-test
usage has already been removed in earlier commits.
1. Tests now use uint256::FromHex() or other constructors wherever
possible without further modification.
2. Tests that can't use uint256::FromHex() because they use input
with non-hex digit characters are
a) modified by dropping the non-hex digit characters if that
provides useful test coverage.
b) dropped if the test without non-hex digit characters does
not provide useful test coverage, e.g. because it is now
duplicated.
Additionally, use BOOST_CHECK_EQUAL where relevant on touched lines
to make error messages more readable.
Tests that are solely testing constructing from a hex string
are dropped, others are modified to use a uint256 constructor
or the arith_uint256 uint64_t constructor.
Since an arith_uint256 can not be constructed from a string
directly, we need to ensure that test coverage on
UintToArith256(uint256::FromHex()) is not reduced.
uint256::FromHex() already has good test coverage, but
the test coverage on UintToArith256() and ArithToUint256()
is increased in this commit by upgrading the `conversion`
test case.
Moreover, since `uint256.h` does not have any dependencies
on `arith_uint256.h`, the conversion tests are moved to
`arith_uint256_tests.cpp` so the dependency can be cleaned
up entirely in a future commit.
This change enables building and installing only `libbitcoinkernel`,
without the need to disable other targets during the project build
system generation.
Add `-ipcbind` option to `bitcoin-node` to listen on an IPC socket and accept
connections from other processes. In the future, there will be an `-ipcconnect`
option added to `bitcoin-wallet` and `bitcoin-node` to allow wallet and gui
processes to connect to the node and access it.
Example usage:
src/bitcoin-node -regtest -debug -ipcbind=unix
src/bitcoin-wallet -regtest -ipcconnect=unix info
src/bitcoin-gui -regtest -ipcconnect=unix
src/bitcoin-mine -regtest -ipcconnect=unix

Our current minimum supported Boost is `1.73.0`. However, when compiling with Boost `1.74.0` (Debian Stable), using Clang `18`, compilation fails with:
```bash

Work around this issue by ignoring this diagnostic for this include. I did attempt to just downgrade the error into a warning, but that did not seem to work. Not a huge fan of inline warning/issue suppression, but this seems like the cleanest thing to do here (and easy to backport to `28.x`).
Can be tested with something like:
```bash
docker pull debian:bookworm
docker run -it debian:bookworm /bin/bash
apt update && apt install ccache cmake git pkg-config libboost-dev libevent-dev python3 libsqlite3-dev lsb-release wget software-properties-common gnupg
git clone https://github.com/bitcoin/bitcoin
wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
./llvm.sh 18
cd bitcoin
cmake -B build -DCMAKE_C_COMPILER=clang-18 -DCMAKE_CXX_COMPILER=clang++-18
cmake --build build -j17

The current logic for file descriptor accounting is pretty convoluted and hard
to follow. This is partially caused by the lack of documentation plus non-intuitive
variable naming (which was more intuitive when fewer things were accounted for, but
hasn't aged well). This has led to this accounting being error-prone and hard to maintain
(as shown in he previous commit).
Redefine some of the constants, plus document what are we accounting for so this can be
extended more easily
Remove FreeBSD workaround to #2695
We are computing our file descriptors limits based on whether we use
poll or select. However, we are taking that into account only partially
(subtracting from fd_max in one case, but from nFD later on). Moreover,
nBind is also only accounted for partially.
Simplify and fix this logic
