do CN CRCX first 

In order to send the MSC's RTP endpoint IP address+port in the initial
SDP, move the MGCP CRCX up to an earlier point in the sequence of
establishing a voice call.

Update the voice call sequence chart to show the effects.

Though the semantic change is rather simple, the patch is rather huge --
things have to happen in a different order, and async waits have to
happen at different times.

The new codec filter helps to carry codec resolution information across
the newly arranged code paths.
