	* pthread_condattr_getclock.c: New file.
	* pthread_condattr_setclock.c: New file.
	* sysdeps/pthread/pthread.h: Declare these new functions.
	* Versions [GLIBC_2.3.3] (libpthread): Add the new functions.
	* Makefile (libpthread-routines): Add the new functions.
	* sysdeps/unix/sysv/linux/internaltypes.h (struct pthread_condattr):
	Renamed field to value.  Document use of the bits.
	* pthread_condattr_getpshared.c: Adjust for struct pthread_condattr
	change.
	* pthread_condattr_setpshared.c: Likewise.
	* sysdeps/unix/sysv/linux/lowlevelcond.sym: Add cond_clock symbol.
	* sysdeps/unix/sysv/linux/i386/bits/pthreadtypes.h (pthread_cond_t):
	Add __clock field.
	* sysdeps/unix/sysv/linux/ia64/bits/pthreadtypes.h: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/bits/pthreadtypes.h: Likewise.
	* sysdeps/unix/sysv/linux/s390/bits/pthreadtypes.h: Likewise.
	* sysdeps/unix/sysv/linux/sh/bits/pthreadtypes.h: Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S:
	Implement clock selection.
	* sysdeps/pthread/pthread_cond_timedwait.c: Likewise.
	* pthread-errnos.sym: Add ENOSYS.
	* sysdeps/unix/sysv/linux/bits/posix_opt.h: Define
	_POSIX_CLOCK_SELECTION.
	* sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

	* sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S: Remove
	invalid .size directive.
