+If a destroyed `pthread_mutex_t` is passed to any of the mutex functions, apps

+### Invalid `pthread_t` handling (targetSdkVersion >= 26)
As part of a long-term goal to remove the global thread list,
and in an attempt to flush out racy code, we changed how an invalid
`pthread_t` is handled. For `pthread_detach`, `pthread_getcpuclockid`,
`pthread_getschedparam`/`pthread_setschedparam`, `pthread_join`, and
`pthread_kill`, instead of returning ESRCH when passed an invalid

POSIX says that `sem_wait` can be interrupted by delivery of a
signal. This wasn't historically true in Android, and when we fixed this
bug we found that existing code relied on the old behavior. To preserve
compatibility, `sem_wait` can only return EINTR on Android if the app
