Change subject: tweak MNCC logging, add RTP info
......................................................................
tweak MNCC logging, add RTP info
Omit "in state FOO", because LOG_TRANS() already logs the state.
Most MNCC "rx" logging was duplicated. Log "rx" only once.
If there is RTP information passed with the MNCC message, log it:
- if there is SDP, log the SDP information.
- if there is no SDP, log the legacy MNCC RTP fields, if any.
One motivation to do this is to get RTP information in ladder diagrams
generated by msc_log_to_ladder.py without the need to add udtrace MNCC
logging to osmo-msc; and also to get RTP info for internal MNCC, where
udtrace doesn't apply, because no unix domain socket is involved in
internal MNCC operation.
