Notable changes

P2P and network changes

- Previously if Bitcoin Core was listening for P2P connections, either using

default settings or via `bind=addr:port` it would always also bind to

`127.0.0.1:8334` to listen for Tor connections. It was not possible to switch

this off, even if the node didn't use Tor. This has been changed and now

`bind=addr:port` results in binding on `addr:port` only. The default behavior

of binding to `0.0.0.0:8333` and `127.0.0.1:8334` has not been changed.

If you are using a `bind=...` configuration without `bind=...=onion` and rely

on the previous implied behavior to accept incoming Tor connections at

`127.0.0.1:8334`, you need to now make this explicit by using

`bind=... bind=127.0.0.1:8334=onion`. (#22729)

- Bitcoin Core will now fail to start up if any of its P2P binds fail, rather

than the previous behaviour where it would only abort startup if all P2P

binds had failed. (#22729)
