Merge branch 'zecke/features/sdp-codec-handling'
Move forward while preserving the legacy handling. Beging to
extract SDP rtpmap information and select codecs atfer this.
It is a foundation we can now build further and better check
ons.

mgcp: Allow to enforce that the codecs need to match
We have a lot of legacy that I am afraid to break. We have
everything in place to make a good codec selection (e.g. if
we can avoid transcoding, pick the one with best quality or
the lowest speed). Right now I have a specific case where
from all options I want to pick GSM. Guard the codec compat
check behind the disallow transcoding option to make sure
to not break legacy application.

mgcp: Turn SDP file parsing in a two stage process
First collect everything we know and the mapping. E.g. a genuis
could remap "3" to "AMR" so we only know the codecs once we are
at the end of the SDP file. Once we have collected everything we
can select the audio codecs. The current code is compatible in
that two codecs will be selected regardless of if they make any
sense or not.
mgcp_set_audio_info could re-use some of our codec information
but then the caller in the MGCP protocol needs to be updated as
well as we use the "I: GSM" information to derive the codec from
there.

mgcp: Move the SDP handling into a separate file/module
The SDP file handling will get more complicated in terms of
codec selection so let's remove it from the protocol handling
before we start blowing it up in size.

mgcp: Remove unused parsing data struct
This struct was removed when we switched to strtok_r for
parsing the data. Remove the left-over.
