sem_clockwait functions.
nptl: Add POSIX-proposed pthread_mutex_clocklock function that

* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
functions. These behave similarly to their "timed" equivalents, but also
accept a clockid_t parameter to determine which clock their timeout should
be measured against. All functions allow waiting against CLOCK_MONOTONIC
and CLOCK_REALTIME. The decision of which clock to be used is made at the
time of the wait (unlike with pthread_condattr_setclock, which requires
the clock choice at initialization time).
Deprecated and removed features, and other changes affecting compatibility:
* The copy_file_range function fails with ENOSYS if the kernel does not
