* Create a new handle
* Send the invite
* Have some state transitions
* Allow to release a call in initial unconfirmed state, confirmed
one with cancel and connected with bye

I had modified my code to do nothing after having sent the PROCEEDING
message. First the MS will issue a DISCONNECT.IND (which I ignored) and
then there will be REL.IND. Let's inform the other leg about this event
and let's assume the call will then be terminated.
With a bit more code the logging will print:
<0001> mncc.c:233 Created call(5001) with MNCC leg(2147483659) IMSI(274018000000001)
<0001> mncc.c:178 RTP set-up continuing with call with leg(2147483659)
<0001> mncc.c:65 Got response, stopping timer on leg(2147483659)
<0002> call.c:51 call(5001) releasing.
Use %zu for size_t arguments, e.g. returned from sizeof.
The code is not tested and might be broken. Parse the setup request
of a MO call, create a new "call" with a MNCC leg and then issue the
call to create a RTP socket. Once this has been done, release the call
as the code to open a second leg has not been written yet.
Connect, re-connect and read messages from the MNCC socket. Dispatch
the event in case the system got disconnected.
Move the app definition to app.h and use it everywhere. Begin with a
new call for mncc.
* It is written in C and using libosmovty and other data structures
* It is using sofia-sip for the SIP handling as a good library for
such a task
* It is using glib for the sofia-sip event loop integration. In the
future we can write our own root context but right now that looks
like a necessary evil. No glib usage is allowed in this code and
only sofia-glib is linked.
