* 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.

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.

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.

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.

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.

f_flow_modify first calls bind, then connect, with MDCX transaction in

during that time, TTCN3 will fail to send the packet:
