Merge #16127: More thread safety annotation coverage
5478d6c logging: thread safety annotations (Anthony Towns) e685ca1 util/system.cpp: add thread safety annotations for dir_locks (Anthony Towns) a788789 test/checkqueue_tests: thread safety annotations (Anthony Towns) 479c584 rpc/blockchain.cpp: thread safety annotations for latestblock (Anthony Towns) 8b5af3d net: fMsgProcWake use LOCK instead of lock_guard (Anthony Towns) de7c5f4 wallet/wallet.h: Remove mutexScanning which was only protecting a single atomic bool (Anthony Towns) c3cf2f5 rpc/blockchain.cpp: Remove g_utxosetscan mutex that is only protecting a single atomic variable (Anthony Towns) Pull request description: In a few cases we need to use `std::mutex` rather than the sync.h primitives. But `std::lock_guard<std::mutex>` doesn't include the clang thread safety annotations unless you also use clang's C library, which means you can't indicate when variables should be guarded by `std::mutex` mutexes. This adds an annotated version of `std::lock_guard<std::mutex>` to threadsafety.h to fix that, and modifies places where `std::mutex` is used to take advantage of the annotations. It's based on top of #16112, and turns the thread safety comments included there into annotations. It also changes the RAII classes in wallet/wallet.h and rpc/blockchain.cpp to just use the atomic<bool> flag for synchronisation rather than having a mutex that doesn't actually guard anything as well. ACKs for top commit: MarcoFalke: ACK 5478d6c 🗾 hebasto: re-ACK 5478d6c, only renamed s/`MutexGuard`/`LockGuard`/, and dropped the commit "test/util_threadnames_tests: add thread safety annotations" since the [previous](#16127 (review)) review. ryanofsky: Code review ACK 5478d6c. Thanks for taking suggestions! Only changes since last review are dropping thread rename test commit d53072e and renaming mutex guard to lock guard Tree-SHA512: 7b00d31f6f2b5a222ec69431eb810a74abf0542db3a65d1bbad54e354c40df2857ec89c00b4a5e466c81ba223267ca95f3f98d5fbc1a1d052a2c3a7d2209790a
