Neels Hofmeyr c8bf895a04 cosmetic: rename to sdp_audio_codecs_foreach() 
Better match the pattern of sdp_audio_codecs_* instead of having
foreach_ in the front. Prepare for prepending osmo_ some day, because I
plan to move the SDP API to a separate library.

Oliver Smith 1063213b38 Add initial CSD support with external MNCC 
Implement and use CSD bearer service logic (with similar audio codec code):
* csd_filter (codec_filter)
* csd_bs (sdp_audio_codec)
* csd_bs_list (sdp_audio_codecs)

Neels Hofmeyr d20dd22082 sdp_msg: s/sdp_audio_codec_/sdp_audio_codecs_ 
Some functions act on a struct sdp_audio_codecs but begin with the name
sdp_audio_codec (singular). That's confusing.

Neels Hofmeyr c9e0ca3d1f sdp_msg: add sdp_audio_codecs_cmp(), add compare flags 
A problem with SDP fmtp handling is visible in this patch: when cmp_fmtp
is true, we compare fmtp strings 1:1, which is not how things should be
done. The intention is to fix fmtp handling in a later patch.

At least there now is a flag to bypass fmtp comparison altogether.

foo_name is intended for a short id, foo_to_str is more accurate naming
here.

Neels Hofmeyr eef4578102 add sdp_msg API: SDP parsing/composition 
Rationale: in order to add full SDP to the MNCC protocol (upcoming patch
I8c3b2de53ffae4ec3a66b9dabf308c290a2c999f), we need to parse and compose SDP
messages. Obviously, libosmo-mgcp-client already contains similar code, but
that is unfortunately heavily glued to the actual MGCP implementation. The
simplest solution is to create this separate implementation, copy-pasting from
the existing libosmo-mgcp-client code as is convenient.

This API is added here to probe whether it works well. When it does, the
intention is to "move it up" to osmo-mgw and overhaul the SDP parsing in our
MGCP client and MGCP server APIs using this same API.
