Harald Welte 717c730731 RAN_Emulation: Support for PS domain
So far, the RAN_Emulation only supported the CS domain, and not PS. Let's
change that so we can start having IuPS related tests.

Harald Welte 955aa94504 BSSGP_Emulation: Abandon "BssgpDecoded" intermediate structure
It originally seemed like a great idea to define a custom record
which aggregates the decoded BSSGP, LLC, L3 and/or SNDCP and passes
it to the individual ConnHdlr.  However, particularly with testcase
interoperability for IuPS in mind, this seems bogus.  Also, we
never really took advantage of this.

Let's now decode as far as we can decode any PDU, and then send the
decoded version of that PDU via the ports between the BSSGP_Emulation
and the ConnHdlr component.

Neels Hofmeyr 9140101cb0 bsc: add TC_ho_neighbor_config_1 thru _7
Add tests to play through various neighbor configurations.
Tests will pass as soon as osmo-bsc I29bca59ab232eddc74e0d4698efb9c9992443983

Add RSL2 to allow triggering handover to BTS 2.

Adjust osmo-bsc.cfg to match the new tests. Also applied in docker-playground
I1c57a04747f5ec004ccf4657954dcb0b003c24fc.

Oliver Smith 1d118ff753 msc: add check IMEI tests
Extend BSC_ConnHdlr with new check IMEI related parameters. Add tests
for check IMEI and check IMEI early for multiple auth variations, as
well as variants where the HLR would respond with NOK or ERR.

Note that we can safely set "check-imei-rqd 0" in f_init(), because the
latest OsmoMSC version already suppors this VTY command.

Two tests do not always pass, sometimes the RAN connection breaks
before the test finishes (TC_lu_imsi_auth_tmsi_check_imei_err and
TC_lu_imsi_auth_tmsi_check_imei_nack). I have added them as expected
errors in the expected-results.xml.

Pau Espin 1a026a52d3 lib/mgcp: Add new port with support to handle multiple MGCP sockets
* Some scenarios like MGW BSC-attached in SCCPlite require handling of
2 MGCP-over-UDP sockets in MGCP Emulation: 1 for regular
libosmomgcp-client from osmo-bsc and another one from the forward socket
from osmo-bsc (of MGCP-over-IPA messages communicated with MSC).

* Old port is kept for backward compatibility with other tests and
enabled by default. It's also interesting to keep it because it makes
tests without special needs (2 sockets) to use the old port/API which
produces simpler code to read and mantain.

* Users of the new port have to enable multi_conn_mode parameter and
expect to interact with port MGCP_CLIENT_MULTI instead of MGCP_CLIENT,
which will offer messages containing information about the UDP
connection being used by that message.

Vadim Yanitskiy f2c3fa9144 library/RAN_Emulation.ttcnpp: fix: properly handle SAPI / DLCI for RANAP
Some of our SMS related test cases are failing. The problem is
that SMS related RAN messages shall be sent on SAPI 3, as per
GSM TS 04.11, section 2.3, while they actually being sent on
SAPI 0.

For the messages coming from the TCs towards OsmoMSC over RANAP,
we need to convert from DLCI to SAPI in f_xmit_raw_l3(). OsmoMSC
also needs to be patched, because it seems to ignore SAPI IE.

Vadim Yanitskiy e06f228be1 library/ranap: enrich both t(s|r)_RANAP_DirectTransfer templates
Instead of having two similar variants of RANAP_DirectTransfer:

  - t(s|r)_RANAP_DirectTransfer, and
  - t(s|r)_RANAP_DirectTransferSAPI,

let's make the first one more flexible, and drop the last one.
This is achieved by introducing two supplementary functions:

  - f_gen_ts_dt_ies(), and
  - f_gen_tr_dt_ies,

which dynamically compose DirectTransfer.protocolIEs.

Vadim Yanitskiy 6c9fafcead library/GSUP_Types.ttcn: refactor PROC_SS IEs generation
Both ts_GSUP_PROC_SS_ERR() and tr_GSUP_PROC_SS_ERR() templates
used to compose the set of GSUP IEs manually, while similar ones
were using both f_gen_ts_ss_ies() and f_gen_tr_ss_ies().

This led to the following problems:

  - tr_GSUP_PROC_SS_ERR was not tolerant to omitted
    message class IE, which was recently introduced;
  - code duplication.

Let's modify the both functions in order to accept an optional
Cause IE value, which is omitted by default, and use them in
the both templates.

Vadim Yanitskiy 7c2c10cbf0 BTS_Tests.ttcn: introduce TC_ho_rach() for handover RACH
The idea of this test case (as can bee seen from its name) is to
verify handover RACH detection. What we basically do is:

1. Activate a logical channel on the BTS side (HO_SYNC for now);
2. Switch the MS (e.g. trxcon) to that channel without waiting
   for Immediate Assignment and sending Access Burst;
3. Send an Access Burst on that channel using RA = HO_REF;
4. Wait for RSL HANDOver DETected from the BTS;
5. Release a dedicated connection.

There is no way to verify if the Handover Reference received
from the MS matches the one that was sent to the BTS. We can
introduce a separate test case that would just send an Access
Burst with RA != HO_REF.
