Merge more changes from svn/asterisk/team/russell/sla_updates

* Add support for private hold.  By setting "hold=private" for a trunk, only
  the station that put the call on hold will be able to retrieve it from hold.
  Also, by setting "hold=private" for a station, any call that station puts
  on hold can only be retrieved by that station.
