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")`.

27c976d11a fix: increase consistency of rpcauth parsing (tdb3)

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

`FORTIFY_SOURCE` should be used if `ENABLE_HARDENING=ON` and optimisations are being used. This should not be coupled to any particular build type, because even if the build type is `Debug`, optimisations might still be in use.

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.
fa9d7d5d20 test: Work around boost compilation error (MarcoFalke)
fa3ecdf778 Revert "build: work around issue with Boost <= 1.80 and Clang >= 18" (MarcoFalke)
Pull request description:
There seems to be an issue compiling the `chainstatemanager_rebalance_caches` test case with some specific versions of Boost in combination with some specific versions of Clang. For example, Boost 1.74 may fail in combination with Clang 18. [1]
The error stems from a mixed-type closeness comparison. Given that the comparison is using floating point, and isn't meant to be exact, work around the compile error by ensuring both sides of the comparison are using the same type (`double`).
This also allows to drop a previous workaround.

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
