CMake parses some paths from the spec of the C compiler, assuming it
will be the linker, resulting in the link to end up with
`-L/usr/lib/gcc/x86_64-w64-mingw32/12-win32` on debian bookworm if both
-win32 and -posix variants are installed, and -win32 is the default
alternative.
This results in the wrong C++ library being linked, missing
std::threads::hardware_concurrency and other threading functions.
To fix this, use the -posix variant of gcc as well when available. This
fixes a regression compared to autotools, where this scenario worked.
940edd6ac2 test: refactor: introduce and use `TRUC_CHILD_MAX_VSIZE` constant (Sebastian Falbesoner)
c16ae71768 test: switch MiniWallet padding unit from weight to vsize (Sebastian Falbesoner)
Pull request description:
This PR is a late follow-up for #30162, where I retrospectively consider the padding unit of choice as a mistake. The weight unit is merely a consensus rule detail and is largely irrelevant from a user's perspective w.r.t. fee-rate calculations and mempool policy rules (e.g. for package relay and TRUC limits), so there doesn't seem to be any value of using a granularity that we can't even guarantee to reach exactly anyway.
Switch to the more natural unit of vsize instead, which simplifies both the padding implementation (no "round up to the next multiple of 4" anymore) and the current tests that take use of this padding. The rather annoying multiplications by `WITNESS_SCALE_FACTOR` can then be removed and weird-looking magic numbers like `4004` can be replaced by numbers that are more connected to actual policy limit constants from the codebase, e.g. `1001` for exceeding `TRUC_CHILD_MAX_VSIZE` by one. The second commits introduces a constant for that.

781c01f580 init: Check mempool arguments in AppInitParameterInteractions (TheCharlatan)
Pull request description:
The for loop around the chain loading logic in `init.cpp` allows users of the GUI to retry once on failure with reindexing without having to manually set the reindex flag on startup. However this current mechanism has problems:
* It is badly documented and has led to confusion among developers and bugs making it into master. Examples:
* https://github.com/bitcoin/bitcoin/pull/28830/files#r1598392660
* https://github.com/bitcoin/bitcoin/pull/30132#issuecomment-2120741121
* It can only ever iterate once, making the choice of a for loop questionable.
* With its large scope it is easy for re-entry bugs to sneak in. Example:
* https://github.com/bitcoin/bitcoin/pull/28830#discussion_r1601589963
Attempt to fix this by moving the bulk of the logic into a separate function and replacing the for loop with a simpler `if` statement.
The diff's in this pull request are best reviewed with `--color-moved-ws=ignore-all-space --color-moved=dimmed-zebra`. The error behaviour can be tested by either manually making `LoadChainstate` return a failure, or deleting some of the block index database files.

Pull request description:
Continues #30005. Closes #17012..
This PR adds PCP (Port Control Protocol) from [RFC6887](https://datatracker.ietf.org/doc/html/rfc6887). This adds, in addition to the existing IPv4 port mapping (which now uses PCP, with fallback to NAT-PMP), support for IPv6 pinholing-that is, opening a port on the firewall to make it reachable.
PCP, like NAT-PMP is a simple UDP-based protocol, and the implementation is self-contained, so this gets rid of lthe libnatpnp dependency without adding a new one. It should otherwise be a drop-in replacement. NAT-PMP fallback is implemented so this will not make router support worse.
For now it is disabled by default, though in the future (not in this PR) we could consider enable it by default to increase the number of connectable nodes without adding significant attack surface.
To test:
```bash
bitcoind -regtest -natpmp=1 -debug=net
```
(most of the changes in this PR are, ironically, removing the libnatpmp dependency and associated build system and build docs)
## TODO
- [x] Default gateway discovery on Linux / FreeBSD
- [x] Default gateway discovery on Windows
- [x] Default gateway discovery on MacOS
- [x] Either solve FreeBSD compile issue (probably upstream issue) or remove FreeBSD support
## Things to consider for follow-up PRs
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658764974 avoid unreachable nets (not given to -onlynet=)

f1daa80521 guix: Drop no longer needed `PATH` modification (Hennadii Stepanov)
Pull request description:
I don't see any reason why this would be necessary in the master branch @ d812cf1189.
Additionally, from https://github.com/bitcoin/bitcoin/pull/30940#pullrequestreview-2322355196:
> 2. I don't understand why "In the Guix environment, `${BASEPREFIX}/${HOST}/native/bin` is added to the `PATH` environment variable," according to the description. Setting this seems indiscriminate, like a sledgehammer approach, something that would cause the guix build to behave differently from normal depends builds and lead to confusing issues like this one.

Pull request description:
Add Cap'n Proto wrapper for the Mining interface introduced in #30200, and its associated types.
This PR combined with #30509 will allow a separate mining process, like the one being implemented in https://github.com/Sjors/bitcoin/pull/48, to connect to the node over IPC, and create, manage, and submit block templates. (#30437 shows another simpler demo of a process using the Mining interface.)

c0a0c72b4d validation: Disable CheckForkWarningConditions for background chainstate (Martin Zumsande)
Pull request description:
The comparison of `m_best_invalid` with the tip of the chainstate makes no sense for the background chainstate and can lead to incorrect log messages.

The for loop has been a long standing source of confusion and bugs, both
because its purpose is not clearly documented and because the body of
the for loop contains a lot of logic.

This makes it clearer which state is being mutated by the function and
facilitates getting rid of the for loop in the following commit. Move
creation of the required options into the function too, such that the
function takes fewer arguments and is more self-contained.

7e3dbe4180 wallet: Write best block to disk before backup (Fabian Jahr)
Pull request description:
I discovered that we don't write the best block to disk when trying to explain the behavior described here: https://github.com/bitcoin/bitcoin/pull/30455#discussion_r1719951882
In the context of that test, the behavior is confusing and I think it also shows that one of the already existing tests in `wallet_assumeutxo.py` doesn't actually test what it says. It only fails because the best block isn't written and actually, the height of the backup that is loaded is at the snapshot height during backup. So it really shouldn't fail since it's past the background sync blocks already.
I'm not sure if this is super relevant in practice though so I am first looking for concept ACKs on the `BackupWallet` code change. Either way, I think this behavior should be documented better if it is left as is and the test should be changed.

Add support for passing CTransaction and CTransactionRef types to IPC
functions.
These types can't be passed currently because IPC serialization code currently
only supports deserializing types that have an Unserialize() method, which
CTransaction does not, because it is supposed to represent immutable
transactions. Work around this by adding a CustomReadField overload that will
call CTransaction's deserialize_type constructor.
These types also can't be passed currently because serializing transactions
requires TransactionSerParams to be set. Fix this by setting TX_WITH_WITNESS as
default serialization parameters for IPC code.
