	* sysdeps/generic/bits/time.h: Define CLOCK_MONOTONIC.
	* sysdeps/posix/clock_getres.c: Define code for CLOCK_REALTIME only
	if not already defined.  Use SYSDEP_GETRES to allow other files to
	provide alternative implementations.
	* sysdeps/unix/sysv/linux/clock_getres.c: New file
	* sysdeps/unix/clock_gettime.c: Define code for CLOCK_REALTIME only
	if not already defined.  Use SYSDEP_GETTIME to allow other files to
	provide alternative implementations.
	* sysdeps/unix/sysv/linux/clock_gettime.c: New file.
	* sysdeps/unix/clock_settime.c: Define code for CLOCK_REALTIME only
	if not already defined.  Use SYSDEP_GETTIME to allow other files to
	provide alternative implementations.
	* sysdeps/unix/sysv/linux/clock_settime.c: New file.
	* sysdeps/unix/clock_nanosleep.c: Use SYSDEP_NANOSLEEP to allow
	other files to provide alternative implementations.  Rearrange
	tests for invalid parameters.
	* sysdeps/unix/sysv/linux/clock_nanosleep.c: New file.
	* sysdeps/unix/sysv/linux/sysconf.c: New file.
	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_POSIX_TIMERS for Linux 2.4.63 and up.
	* sysdeps/unix/sysv/linux/bits/posix_opt.h: Define
	_POSIX_MONOTONIC_CLOCK.
