The mutex (required by TestBlockValidity) must be held after creating
the block, until TestBlockValidity is called. Otherwise, it is possible
that the chain advances in the meantime and leads to a crash in
TestBlockValidity:
Assertion failed: pindexPrev && pindexPrev == chainstate.m_chain.Tip() (validation.cpp: TestBlockValidity: 4338)

After port collisions are no longer tolerated but lead to
a startup failure in v28.0, local setups of multiple nodes,
each with a different -port value would not be possible anymore
due to collision of the onion default port - even if the nodes
were using tor or not interested in receiving onion inbound connections.
Fix this by deriving the onion listening port to be -port + 1.

The current code does not have a bug, but is implicitly casting -1 to
65535 and the sanitizer has no way to know whether we intend that or
not.

This makes it easier to track which spots refer to an nId

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.

Same as in `DecodeSecret`, we should also clear out the secret data from
the vector resulting from the Base58Check parsing for xprv keys. Note
that the if condition is needed in order to avoid UB, see #14242 (commit
d855e4cac8).

The comparison of m_best_invalid with the tip of the respective chainstate
makes no sense for the background chainstate, and can lead to incorrect
error messages.

The crash occurs because 'WalletController::removeAndDeleteWallet' is called
twice for the same wallet model: first in the GUI's button connected function
'WalletController::closeWallet', and then again when the backend emits the
'WalletModel::unload' signal.
This causes the issue because 'removeAndDeleteWallet' inlines an
erase(std::remove()). So, if 'std::remove' returns an iterator to the end
(indicating the element wasn't found because it was already erased), the
subsequent call to 'erase' leads to an undefined behavior.

Exercising and verifying the following points:
1. An IBD node can sync headers from an AssumeUTXO node at
any time.
2. IBD nodes do not request historical blocks from AssumeUTXO
nodes while they are syncing the background-chain.
3. The assumeUTXO node dynamically adjusts the network services
it offers according to its state.
4. IBD nodes can fully sync from AssumeUTXO nodes after they
finish the background-chain sync.
Github-Pull: bitcoin/bitcoin#30807
Rebased-From: 992f83bb6f
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.

Currently, builds of libevent in depends, using CMake, fail on some
systems, like Alpine, with the following:
```bash
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c: In function 'evmap_signal_add_':
/bitcoin/depends/work/build/aarch64-unknown-linux-musl/libevent/2.1.12-stable-1516ed47ea8/evmap.c:456:31: error: 'NSIG' undeclared (first use in this function)
456 | if (sig < 0 || sig >= NSIG)
```
From what I can tell the `_GNU_SOURCE` "detection" in libevents CMake build
system, never? really worked, and it's not clear what a nice fix is.
For now, always use `_GNU_SOURCE` when building libevent in depends.
