	When hunting a conn use count bug, it was very hard to figure out who's (not) using the conn. To ease tracking down this bug and future bugs, explicitly name what a conn is being reserved for, and track in a bit mask. Show in the DREF logs what uses and un-uses a conn. See the test expectation updates, which nicely show how that clarifies the state of the conn in the logs. On errors, log them, but don't fail hard: if one conn use/un-use fails, we don't want to crash the entire MSC before we have to. Change-Id: I259aa0eec41efebb4c8221275219433eafaa549b

2017-08-29	Implement AoIP, port to M3UA SIGTRAN (large addition and refactoring)	Philipp Maier	1	-1/+12
	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.

2017-08-23	04.08: log protocol discriminators and message types by name	Neels Hofmeyr	1	-53/+53
	On incoming 04.08 messages, we log only the protocol discriminator in decimal. Enhance: log pdisc and message type in hex, and also log the protocol and message type as human readable string. Also adjust the msc_vlr tests' log statements for wrapped rx/tx functions of dtap from/to the MS. Adjust the expected output of msc_vlr_tests.

2017-08-08	Implement IuCS (large refactoring and addition)	Neels Hofmeyr	1	-63/+67
	osmo-nitb becomes osmo-msc add DIUCS debug log constant add iucs.[hc] add msc vty, remove nitb vty add libiudummy, to avoid linking Iu deps in tests Use new msc_tx_dtap() instead of gsm0808_submit_dtap() libmgcp: add mgcpgw client API bridge calls via mgcpgw Enable MSC specific CTRL commands, bsc_base_ctrl_cmds_install() still needs to be split up.
