Update.

	* include/time.h: Define CLOCK_IDFIELD_SIZE.
	* sysdeps/posix/clock_getres.c: Recognize thread CPU clock IDs.
	* sysdeps/unix/clock_gettime.c: Likewise.
	* sysdeps/unix/clock_settime.c: Likewise.
	* sysdeps/unix/clock_nanosleep.c (CPUCLOCK_P): Adjust for new
	clock id for thread CPU clocks.
