[L] Change in osmo-mgw[master]: mgcp_codec: fix codec decision

by dexter

Attention is currently required from: pespin. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-mgw/+/32218 to look at the new patch set (#6). Change subject: mgcp_codec: fix codec decision ...................................................................... mgcp_codec: fix codec decision Unfortunately OsmoMGW was never really tested with multiple different codecs on either side of the connection. While OsmoMSC and OsmoBSC only assign exactly one codec on each side this has never been a problem, however it might become a problem when a call againt assigns multiple codecs on one side. This has been observed in a setup where OsmoMGW had one leg towards an external call agent. Also due to recent upgrades to the TTCN3 tests we are now able to simulate different codecs on both sides to pinpoint issues. Testing has shown that OsmoMGW has difficulties with multiple codecs. The reason for this is that the function that makes the codec decision was not fully finished. So let's finish the codec decision function and let's also use that decision when patching the payload type of outgoing RTP packets.
