  r1059 | rmudgett | 2009-09-02 14:49:58 -0500 (Wed, 02 Sep 2009) | 14 lines
  
  Cleaned up scheduled events handling code.
  
  *  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.
........
  r1060 | rmudgett | 2009-09-02 15:04:03 -0500 (Wed, 02 Sep 2009) | 5 lines
  
  Optimized calls to pri_schedule_del().
  
  There is no need to test if a scheduled event is running before calling
  pri_schedule_del().
........
  r1061 | rmudgett | 2009-09-02 15:19:40 -0500 (Wed, 02 Sep 2009) | 2 lines
  
  Converted Q931_CALL_STATE_xxx defines to an enum.
