Update.

	* posix/getconf.c: Add support for many more POSIX options.
	* sysdeps/posix/sysconf.c: Likewise.
	* sysdeps/generic/bits/confname.h: Add many more POSIX options.
	* sysdeps/mach/hurd/bits/posix_opt.h: Add _POSIX_REGEXP and
	_POSIX_SHELL.
	* sysdeps/unix/sysv/linux/bits/posix_opt.h: Likewise.
	* sysdeps/unix/sysv/linux/i386/bits/time.h: Rename __CLOCK_HIGHRES to
	CLOCK_PROCESS_CPUTIME_ID.  Add define CLOCK_MONOTONIC and
	CLOCK_THREAD_CPUTIME_ID.
	* sysdeps/unix/i386/clock_getcpuclockid.c: Set *clock_id to
	CLOCK_PROCESS_CPUTIME_ID.
	* sysdeps/unix/i386/i586/clock_getres.c: Change for renaming of
	__CLOCK_HIGHRES to CLOCK_PROCESS_CPUTIME_ID.  Handle
	CLOCK_THREAD_CPUTIME_ID and CLOCK_MONOTONIC the same.
	* sysdeps/unix/i386/i586/clock_gettime.c: Likewise.
