If the mutex usage verification framework is enabled and it detects a mutex usage error, report this error and mark the test as failed. This detects most usage errors, but not all cases of using uninitialized memory (which is impossible in full generality) and not leaks due to missing free (which will be handled in a subsequent commit).
