* Fixed pri_schedule_event() to return 0 on error instead of -1. Zero is
a safer value to return. Users would not think that a timer was
scheduled.
* Fixed potential for pri_schedule_del() to write out of bounds of
pri_sched[]. The out of bounds access could occur when
pri_schedule_event() returned -1.
* Made use all pri_sched[] entries. pri_sched[0] was previously unused.
* Removed some unneeded code and recursion since scheduling only runs on
master D channel structures.
* Added doxygen comments.
* Renamed struct pri *pri variables to struct pri *ctrl in this file.
