	* Fixed bug where resetting a timer that was not at the head
	of one of the task timer chains resulted in the Timer Server
	task waking up too far in the future.
	* Added rtems_timer_get_information() directive to support testing.
	* src/timerserver.c, include/rtems/rtems/timer.h,
	* src/timergetinfo.c: New file.
	* src/Makefile.am: Modified to reflect above.
