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.

Adds LockGuard helper in threadsafety.h to replace lock_guard<mutex> when LOCK(Mutex) isn't available for use.

A separate flag is desirable as the logging can be noisy and thus may need to be disabled without affecting other logging. This could help debug issues where there may be race conditions at play, such as #12978.

2020-01-03Add VALIDATION to BCLog::LogFlagsJeffrey Czyz
This flag is for logging from within CValidationInterface (see #12994). A separate flag is desirable as the logging can be noisy and thus may need to be disabled without affecting other logging.

2019-10-15util: Filter control characters out of log messagesWladimir J. van der Laan
Belts and suspenders: make sure outgoing log messages don't contain potentially suspicious characters, such as terminal control codes. This escapes control characters except newline ('\n') in C syntax. It escapes instead of removes them to still allow for troubleshooting issues where they accidentally end up in strings.

This ensures log messages prior to StartLogging() are replayed to the console as well as to the debug log file.

StartLogging() is used to mark the start of logging generically, whether using -printtoconsole or -debuglogfile.
