Description

In OsmoMGW, it is already possible to configure the DSCP value. We also need it for OsmoBTS.

I've tried the related setsockopt() in /src/common/rsl.c:bind_rtp() without success, it seems that it is overwritten later by libortp.

OsmoBTS uses libosmo-abis, which in turn uses libortp for the RTP connections.

I will add a osmo_rtp_socket_set_dscp() function, which calls rtp_session_set_dscp() from libortp, to libosmo-abis and then use it in OsmoBTS.
