[L] Change in osmo-msc[master]: do CN CRCX first

neels has submitted this change. ( https://gerrit.osmocom.org/c/osmo-msc/+/31740 ) Change subject: do CN CRCX first ...................................................................... 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.
