nptl: Add POSIX-proposed pthread_mutex_clocklock

Browse Source 
Add POSIX-proposed pthread_mutex_clocklock function that works like
pthread_mutex_timedlock but takes a clockid parameter to measure the
abstime parameter against.

	* sysdeps/nptl/pthread.h: Add pthread_mutex_clocklock.
	* nptl/DESIGN-systemtap-probes.txt: Likewise.
	* nptl/pthread_mutex_timedlock.c
	(__pthread_mutex_clocklock_common): Rename from
	__pthread_mutex_timedlock and add clockid parameter. Pass this
	parameter to lll_clocklock and lll_clocklock_elision in place of
	CLOCK_REALTIME. (__pthread_mutex_clocklock): New function to add
	LIBC_PROBE and validate clockid parameter before calling
	__pthread_mutex_clocklock_common. (__pthread_mutex_timedlock): New
	implementation to add LIBC_PROBE and calls
	__pthread_mutex_clocklock_common passing CLOCK_REALTIME as the
	clockid.
	* nptl/Makefile: Add tst-mutex11.c.
	* nptl/tst-abstime.c (th): Add tests for pthread_mutex_clocklock.
	* nptl/tst-mutex11.c: New tests for passing invalid and unsupported
	clockid parameters to pthread_mutex_clocklock.
	* nptl/tst-mutex5.c (do_test_clock): Rename from do_test and take
	clockid parameter to indicate which clock to be used. Call
	pthread_mutex_timedlock or pthread_mutex_clocklock as appropriate.
	(do_test): Call do_test_clock to separately test
	pthread_mutex_timedlock, pthread_mutex_clocklock(CLOCK_REALTIME)
	and pthread_mutex_clocklock(CLOCK_MONOTONIC).
	* nptl/tst-mutex9.c: Likewise.
	* nptl/Versions (GLIBC_2.30): Add pthread_mutex_clocklock.
