Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)
This was originally a long series of commits converging to the final result seen in this patch. It does not make much sense to review the smaller steps' trial and error, we need to review this entire change as a whole. Implement AoIP in osmo-msc and osmo-bsc. Change over to the new libosmo-sigtran API with support for proper SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and IuPS interfaces. From here on, a separate osmo-stp process is required for SCCP routing between OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new M3UA SIGTRAN. Patch-by: pmaier, nhofmeyr, laforge Change-Id: I5ae4e05ee7c57cad341ea5e86af37c1f6b0ffa77
