* Added task-based timers to the Timer Manager. This added three
new directives:
- rtems_timer_initiate_server
- rtems_timer_server_fire_after
- rtems_timer_server_fire_when
In the process of doing this, a number of cleanups were made.
* src/timerserver.c, src/timerserverfireafter.c,
src/timerserverfirewhen.c: New files.
* include/timer/timer.h: Added new prototypes and supporting types.
* inline/rtems/rtems/timer.h, macros/rtems/rtems/timer.h: Enhanced
_Timer_Is_interval_class() to cover the class TIMER_INTERVAL_ON_TASK.
* src/Makefile.am: Accounted for new files.
* src/rtemstimer.c: Added initialization of _Timer_Server variable.
* src/timercancel.c, src/timerreset.c: Account for addition
of timer classes. Also corrected the headers.
* src/timercreate.c, src/timerdelete.c, src/timerfireafter.c,
src/timerfireafter.c, src/timerident.c: Corrected header.
