* MGCP-over-IPA handling in MSC_ConnectionHandler means we need to use
the new MGCP_CLIENT_MULTI port since we'll be managing MGCP messages
from 2 different UDP connections, and we need to be able to route
answers correctly. As a result, parameter multi_conn_mode is enabled for
SCCPlite and all code adapted to use that port in that type of scenario.
* iDuring calls when on SCCPlite, send a full (all-required-params-in)
CRCX through the MGCP-over-IPA connection towards the BSC in order to
emulate the MSC, and expect the correct answer back. This way we test
BSC funcionality to forward MGCP messages coming from MSC works as
expected.

* 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.

* TTCN3 code was not ACKing the DLCXs, and as a result retransmitted
DLCX BSC->MGW were being counted as 2nd DLCX.
* In SCCPLite, only 1 DLCX is expected BSC->MGW, because the BSC only
takes care of the BTS-side conn in the endpoint, while MSC takes care of
the MSC-side conn (which is not sent in this case because doesn't really
involved the BSC other than forwarding the message, which will already
be tested in other places in forthcoming commits).
* Getting rid of retransmissions by ACKing the DLCX, it unconvers a bug
in TC_ho_out_fail_no_ho_detect when on AoIP, where BSC only deletes one
of the 2 previously created connections.
* Code is refactored into the function because its logic is made more
complex, and may be even more complex in forthcoming commits when we add
MGCP-over-IPA forwarding verification support.

This test case is aimed to verify HLR-/EUSE-initiated abort of an
active SS/USSD session according to the following scenario:
1. (HLR/EUSE -> MSC) GSUP_PROC_SS_REQ with random facility;
2. Network-originated connection establishment:
2.a. (MSC -> BSC -> MS) Paging Request;
2.b. ...
2.c. (MS -> BSC -> MSC) Paging Response;
3. (MSC -> MS) GSM 04.80 REGISTER with random facility;
4. (HLR/EUSE -> MSC) GSUP_PROC_SS_ERR (abort);
5. (MSC -> MS) GSM 04.80 RELEASE COMPLETE;
6. Connection release.
As can be seen, HLR/EUSE initiates the session abort right after
the GSM 04.80 REGISTER message is delivered to the MS, and just
before the MS sends anything back in response.

The idea of this test case is to check that OsmoMSC does inform
HLR/EUSE that a subscriber did not respond to Paging Request in
case of network-originated SS/USSD.
Both f_expect_gsup_msg() and f_expect_dtap_msg() were extended
with optional timeout value, as we need to wait longer than
2.0 seconds (default). Let's stick to 10.0 seconds.

The idea of this test case is to check that OsmoMSC properly
rejects SS/USSD requests for unknown subscribers.
Running this test case against the current OsmoMSC helped
to discover several problems:
- OsmoMSC doesn't print anything in such cases;
- IMSI in the response error message is empty;
- both session state and ID IEs are omited;
which are going to be fixed soon.

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.

Each test can now plug in different acctions to be done by the emulated
MSC, by passing a BssmapCreateCallback RAN_Emaulation callback to
f_init(). Old hardcoded behaviour (main()) is renamed and used in
laready existing tests.
New infrastructure provides a generic BssmapCreateCallback taking care
of required boilerplate, so new tests/users only need to define a new
callback calling that generic one with a function pointer where all test
logic is implemented.

The testcase failed becaues of an unexpected RSL Error Indication from
the LAPDm system which was in the RSL emulation queue when tearing down
the test environment.
By calling f_rsl_chan_deact() the queue gets flushed until the RSL
deactivate channel is received. It's also more clean to release the
channel.
