  * nua: Ignore CANCEL of incoming request if we have already sent a final response. Problem reported by Mike Jerris.

nua: fixed problems in state machines.
Pekka Pessi <first.lastname@nokia.com>**20070214201847
   
 These problems are mostly introduced in 1.12.5:
 - assert failed if INVITE was received when calling
   (reported by Michael Jerris)
 - assert failed if nua_invite() was called second time before receiving
   final response to first INVITE (ditto)
 - ACK is now always sent if session was terminated after receiving 2XX
 - if nua has a pending incoming INVITE request, return 491 to
   nua_invite()

nta.c: return 481 response to CANCEL if INVITE transaction was successful
According to the RFC 3261 state diagram the INVITE transaction is destroyed
 immediately when a final 2XX series response is sent. Now nta returns a 481
 response to CANCEL if it finds an INVITE server transaction that was
 responded with a 2XX success response.
