Pau Espin 4d0e5e521b lib/RAN: Introduce CTRL_CLIENT port to access CTRL muxed in RAN IPA conn 
This is the case for SCCPlite between BSC and MSC (or BSC-NAT). MGCP and
CTRL can be multiplexed over the same underlaying IPA conn.

Pau Espin 955491872e bsc: Only append Osmux IEs in BSSAP AoIP 
Previous to this commit, BSSAP Reset (Ack) messages contained Osmux
Support IE even if transport was SCCPLite, where those IEs are actually
meaningless.

Pau Espin c6b78ff2f9 Add and set transport field for RanOps structure 
This will allow RAN_Emulation to have better knowledge on the protocol
stack in use, and behave differently based on that information.
For intance, forthcoming commit will append OsmuxSupport IE only if
transport is BSSAP AoIP.

Pau Espin c6a53dbb2a bsc: Introduce Osmux infra and one test for osmo-bsc 
Test verifies once osmux is enabled in osmo-bsc, BSSMAP RESET (ACK)
contains Osmux Support IE and that it correctly handles BSSMAP ASsign
Req with Osmux CID.

Harald Welte 03d4e2b8f2 RAN_Emulation: Fix IMSI table lookup on RANAP paging 
We need to check explicitly for '== null'.  isvalue() is of no help
here, as 'null' apparently is a value in TTCN-3.

Harald Welte 475a2c1d2c move as_iu_release_compl_disc from BSC_ConnHdlr to RAN_Emulation 
... this way other tests beyond MSC_Tests.ttcn can use it.

Harald Welte 5b02762adf RAN_Emulation: Add RANAP support 
So far, RAN_Emulation only handled BSSAP and hence could be used
to emulate BSCs towards the MSC.  Let's extend it with RANAP support
so we can also emulate RNCs towards the MSC.

We try to share as much code and logic as possible betweeb the two.

Harald Welte 2fce7887f4 RAN_Emulation: Modularize protocol support 
The RAN_Emulation currently unconditionally provides BSSAP and MGCP support.
Let's re-structure the code so that support for those protocols is now
possible to enable/disable at compile time.

This patch is in preparation of introducing RANAP support in RAN_Emulation.
