For SI tests, it is necessary to first startup the VTY, then issue some config

At the time of writing Ief0d9b096feeee7d37b5f2429dd3e80de0161806 I wasn't aware
of the 'inout' keyword, which allows to pass the counter list by reference.
Rather modify the counter lists in-place. Instead of requiring
list := f_counter_name_vals_add(list, ...)
rather implement by directly modifying list:

tests locally produced unexpected results.

The TC_ho_neighbor_config_* tests sometimes take longer than 30 seconds,
because they run multiple handovers. Since they don't have access to the
Test_CT, they cannot restart the T_guard. The simplest solution is to choose a
longer T_guard timeout for those tests specifically, by adding an argument to
f_init(). (A longer timeout for those tests is following in another patch.)
Why f_init()? Assigning a different default value to T_guard seems to not be
possible, but a different timeout value can be passed to T_guard.start(), which
happens in f_init().

Handover testing required passing MSC and BSC addresses to f_tc_* functions and
added pars.handover.sccp_addr_msc and .handover.sccp_addr_bsc.
MSC pool tests added a separate sub-record pars.mscpool which also contains
these two fields.
Move them both up one level, to form a single pair of pars.sccp_addr_msc and
pars.sccp_addr_bsc.
This eliminates the pars.handover sub-record.

In f_probe_for_handover disable the RSL emulation before the vty handover
command. Otherwise, osmo-bsc may be too fast to issue the handoverCommand, so
that RSLem still handles it and says: "RSL for unknown Dchan".
(f_probe_for_handover() receives the handoverCommand directly, just to detect
whether a handover would be initiated, and then quickly aborts the handover
procedure.)

The testcase TC_paging_resp_unsol expects the BSC to close the channel
when an unsolicit paging response is received. This expectation is due
to the fact that osmo-bsc supports multiple MSC, which is not specified
in 3gpp specs. Therefore the BSC needs to know which MSC is in charge.
However, with MT-CSFB calls it is a normal situation that the BSC
receives a paging response on abis without sending a paging first since
the MSC has paged the UE via the SGs interface. In those cases we expect
the BSC to forward the paging response to the first configured MSC.

Since osmo-bsc commit "neighbor config: allow re-using ARFCN+BSIC pairs"
(I29bca59ab232eddc74e0d4698efb9c9992443983), osmo-bsc considers only those
cells as neighbors that are explicitly listed, or all local cells if none are
listed. This lead to breaking TC_ho_int, because the osmo-bsc.cfg has only one
remote-cell neighbor for bts 0, and hence a handover to local cell bts 1 is now
regarded as invalid.
The remote-cell neighbor is needed for inter-BSC handover tests; also consider
that the TC_ho_neighbor_config_* tests each place individual neighbor
configuration by live VTY interaction.
Hence make all of these tests more robust: remove the neighbor config from the
osmo-bsc.cfg file, and instead include VTY interaction for each test case that
sets the particularly needed neighbor configuration at runtime.
An analogous osmo-bsc.cfg change in docker-playground is in change
If44dd6b578cdc55076c8180707d1c2d69fe5f2a8.
(It is not actually harmful to leave the neighbor config in osmo-bsc.cfg, but
remove that since it is also not needed anymore.)

Make sure that the RR is released only after the MSC has sent the Clear Command:
- first expect a Clear Request from osmo-bsc and return a Clear Command,
- only then accept RR release messages.
See 3GPP TS 48.008 3.1.5.3.3 "Abnormal Conditions": "The terrestrial resource
in the old BSS shall remain assigned until a CLEAR COMMAND message is received
from the MSC"
osmo-bsc already complies, the test should continue to pass.

BSC waits to receive a ClearCommand in response to its ClearRequest
before it starts tearing down the MGCP conn on the MSC-side of the MGW
endpoint.
As a result, expected DLCX was not being sent which made test fail.
However, currently test still fails because current osmo-bsc master
sends a repeated ClearRequest message in this scenario.

* 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

* 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.

* 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.
