posix: Implement self-contained POSIX semaphores
For semaphore object pointer and object validation see
POSIX_SEMAPHORE_VALIDATE_OBJECT().
Destruction or close of a busy semaphore returns an error status. The
object is not flushed.
POSIX semaphores are now available in all configurations and no longer
depend on --enable-posix.
Update #2514.
Update #3116.
