If a session was terminated because of a error response returned to a
request (as specified by RFC 5157), the nua_i_state event was not sent.

Even with this fix, if a dialog has multiple usages, the event usages can be
terminated without any indication to the application.

Delay sending ACK and subsequent transition of call to the ready state when
the 200 OK response to the INVITE is received if the SDP Offer/Answer
exchange using UPDATE/PRACK was still incomplete.

Previously, if the O/A using UPDATE or PRACK was incomplete and an 200 OK
was received, the call setup logic regarded this as a fatal error and
terminated the call.

Thanks for Mike Jerris for detecting and reporting this bug.

The transaction matching logic failed on server side when the To URI was
changed between INVITE and ACK. Now it is possible to change the To/From URI
in nua_ack(), too.

Binary API was changed, too, and accessor function nta_outgoing_branch() was
added.

nua_session.c: when sending/receiving an UPDATE while session is ready use callstate calling/received

When UPDATE is sent during an established session, indicate progress with
callstate nua_callstate_calling in nua_i_state event. Likewise, when UPDATE
is received, but responding to it is left up to application, indicate
progress with callstate nua_callstate_received (instead of
nua_callstate_ready).

The problem and crash with session timers was reported by Fabio Margarido.

Now following RFC 4028 more closely. There are test cases for UAS and UAC
refreshing the session with INVITE and UPDATE, and a test case where UPDATE
is filtered away until non-refreshing party sends BYE.

The re-INVITE/UPDATE refresh is sent around middle of expiration time (e.g.,
if expiration time is 3600 seconds, it is sent 1795..1805 seconds after the
previous refresh).

The non-refreshing party now sends a BYE request before two thirds of
session expiration time has elapsed without session refresh request.

but flush the cached username/password pairs from authentication clients.

Now handle gracefully the case where the final response is delayed because
the PRACK to initial 100rel response has not been received and the client
CANCELs the INVITE request.

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()

It is not possible to cast function pointers to (void *) in C99

Fabio Margarido reported that the BYE is not sent upon certain error
conditions. This was because state machine does not allow sending duplicate
BYE in terminating state. Usually, the call state machine switches to
terminating state upon sending BYE.  However, certain error conditions (like
not receiving ACK) causes the session to terminate, and the session state is
change to terminating state outside BYE.

The fix here changes the behaviour of internally generated BYE requests,
they do not change the session state to terminating nor they check if the
session state is already terminating.
