  Properly handle 200 and unknown responses conatined in NOTIFY requests received in response to REFER requests.
  
  This patch fixes the way asterisk handles NOTIFY requests received in response to REFER requests.  These changes to NOTIFY handler were first introduced in r217482.  This new change properly handles the 200 response by queueing an AST_TRANSFER_SUCCESS control frame and also prevents that control frame from being queued when provisional and unknown responses are received.
