Merge #19337: sync: detect double lock from the same thread
95975dd08d8fdaaeaf28e0d06b861ce2748c17b6 sync: detect double lock from the same thread (Vasil Dimov)
4df6567e4cbb4677e8048de2f8008612e1b860b9 sync: make EnterCritical() & push_lock() type safe (Vasil Dimov)
Pull request description:
Double lock of the same (non-recursive) mutex from the same thread would produce an undefined behavior. Detect this from `DEBUG_LOCKORDER` and react similarly to the deadlock detection.
This came up during discussion in another, related PR: https://github.com/bitcoin/bitcoin/pull/19238#discussion_r442394521.
