  Log Message:
  -----------
  sanitizer_common: add deadlock detection to the Mutex2

    Copy internal deadlock detector from tsan to sanitizer_common
    (with some cosmetic changes).
    Tsan version will be deleted in subsequent changes.
    This allows us to switch tsan to the sanitizer_common mutex
    and remove tsan's mutex.
