* Per PR147 addressed problems when reseting and inserting a timer
into a timer chain that did not honor time passage since the last
time the timer server was scheduled and the new insertion.
* sp31/sp31.scn, sp31/task1.c: Added test code to detect this case.
* 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.
* sp31/init.c, sp31/system.h, sp31/task1.c: Modified to test for
above condition.
* Added tests for task-based timers. This included the new tests
sp30 and sp31.
* Makefile.am, configure.ac: Modified to reflect new tests and files.
* sp09/screen14.c, sp09/sp09.scn: Modified to add error checks
for task-based timer services.
* sp30/.cvsignore, sp30/Makefile.am, sp30/init.c, sp30/resume.c,
sp30/sp30.doc, sp30/sp30.scn, sp30/system.h, sp30/task1.c,
sp31/.cvsignore, sp31/Makefile.am, sp31/delay.c, sp31/init.c,
sp31/prtime.c, sp31/sp31.doc, sp31/sp31.scn, sp31/system.h,
sp31/task1.c: New files.
