  Simplify locking code for REDIRECTING interception macro when forwarding a call.
  
  Simplified the locking code by using a local copy of the redirecting party
  information in app_dial.c:do_forward() and app_queue.c:wait_for_answer()
  for launching the REDIRECTING interception macro when a call is forwarded.
  
  Reduced the lock time of the 'o->chan' and 'in' channels.
