to allocate our limited outbound slots correctly, and to ensure addnode
connections benefit from their intended protections.
Our addnode logic usually connects the addnode peers before the automatic
outbound logic does, but not always, as a connection race can occur. If an
addnode peer disconnects us and if it was the only one from its network, there
can be a race between reconnecting to it with the addnode thread, and it being
picked as automatic network-specific outbound peer. Or our internet connection
or router, or the addnode peer, could be temporarily offline, and then return
online during the automatic outbound thread. Or we could add a new manual peer
using the addnode RPC at that time.
The race can be more apparent when our node doesn't know many peers, or with
networks like cjdns that currently have few bitcoin peers.
When an addnode peer is connected as an automatic outbound peer and is the only
connection we have to a network, it can be protected by our new outbound
eviction logic and persist in the "wrong role".

Finally, there does not seem to be a reason to make block-relay or short-lived
feeler connections to addnode peers, as the addnode logic will ensure we connect
to them if they are up, within the addnode connection limit.
Fix these issues by checking if the address is an addnode peer in our automatic
outbound connection logic.

defdf67765 contrib: use a raw string for a regular expression literal that contains backslashes in signet/miner (muxator)
Pull request description:
Running `contrib/signet/miner` under python >= 3.12 causes a `SyntaxWarning`. The problem was already present in previous versions, but it only triggered a `DeprecationWarning`, which was not shown by default.

3c61c60b90 build: Add an old hack to remove bind_at_load from libtool. (Cory Fields)
45257601da build: remove -bind_at_load usage (fanquake)
Pull request description:
This is deprecated on macOS:
```bash
ld: warning: -bind_at_load is deprecated on macOS
```
and likely redundant anyways, given the behaviour of dyld3.
Unfortunately libtool is still injecting a `-bind_at_load`, because it's version check is broken:
```bash
# Don't allow lazy linking, it breaks C++ global constructors
# But is supposedly fixed on 10.4 or later (yay!).
if test CXX = "$tagname"; then
case ${MACOSX_DEPLOYMENT_TARGET-10.0} in
10.[0123])
func_append compile_command " $wl-bind_at_load"
func_append finalize_command " $wl-bind_at_load"
;;
esac
fi
```
so this adds another change to strip them out at the end of configure.
Note that anywhere the ld64 warnings are being emitted, we are already not adding this flag to our hardened ldflags, because of `-Wl,-fatal_warnings`.

fa6b053b5c mempool: persist with XOR (MarcoFalke)
Pull request description:
Currently the `mempool.dat` file stores data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan the file and move it into quarantine, or delete it, or corrupt it.
While the local wallet is expected to re-submit any pending transactions, unrelated transactions may be missing from the mempool after a restart. This may cause fee estimates to be off, or may cause block relay to be slower.
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat file when writing or reading it.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat file. Any program that intentionally wants to mess with the dat file can still trivially do so.
