Modified files:
	linuxthreads/sysdeps/pthread: timer_settime.c 

Log message:
	(timer_settime): Takes advantage of new return value from
	__timer_thread_queue_timer to avoid waking up timer thread unnecessarily.
	(timer_settime): Tighter critical regions: avoids making system calls while
	holding timer mutex, and a few computations were moved outside of the mutex
	as well.
	Use appropriate list unlink function in all places: idempotent one for timers,
	non-idempotent one for thread nodes.
