* 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.
