Neels Hofmeyr d767c73a1f implement re-assignment to match codecs ... This is the last missing piece that allows osmo-msc to make good TFO codecs choices. Since the codec_filter, osmo-msc properly gathers codec options and limitations. But the MO call leg still assigns a voice channel before getting a response from the MT call leg, and is then stuck with that. Add the capability to adjust the MO call leg's codec in case the MT side needs a different codec for TFO. This is only relevant for 2G; on 3G we always have AMR/IuUP. For inter-MSC handover, keep the behavior unchanged: offer only the currently assigned codec to the remote side. Codec-changing HO should be equally trivial to implement, but that is for another day. msc_vlr_test_call's codec tests are adjusted to test the new feature in Ib933554f826c1b4347dfa3f6c4f6fe086be8b133. For now, avoid change in these tests by validating the first codec in SDP lists only.
