This makes numerous tests fail, where the test does not properly release

To be able to invoke perform_clear() also in tests where the VTY isn't
used, in f_logp() only access the VTY when it is actually ready.
Otherwise this causes an error and a failed test, for no good reason.

Cause GSM0808_CAUSE_MS_NOT_EQUIPPED is to be transmitted only in the case
BSC receives a RelInd from the MS/BTS. In this test, an ErrorInd is
sent, as in TC_rll_err_ind_sapi_n_reject, so it is expected that the
BSC will send the N_Reject message with cause
GSM0808_CAUSE_BSS_NOT_EQUIPPED.

IPA_Emulation component was marked with the "alive" type recently, in
order to avoid race conditions leading to errors during tear down of the
test.
It turns out, the way "alive" keeps the component alive is by means of
not closing the sockets when the component is stopped. As a result,
TC_rsl_drop_counter test stopped working properly because it was
specting a TCP FIN to be sent to osmo-bsc when the component was
stopped.
In order to fix it, add a new CFG port to the IPA_Emulation component on
which one can operate. Add a a new method to tell the component to close
the socket.
Then, put that in BSC_Tests into a function which was actually unsued
until now, and use it in the test in order to have the specific logic
enclosed in a function helper.

In the out-of-this-BSC handover tests, a neighbor config of LAC 99 left
behind from a previous test obstructed the test from working:
% BTS 0 already had neighbor LAC:99 ARFCN-BSIC:123-45
% ERROR: duplicate Cell ID in neighbor config, with differing ARFCN+BSIC: LAC:99 ARFCN-BSIC:123-any

According to feedback received from TITAN developers in
https://www.eclipse.org/forums/index.php?t=msg&th=1106652&goto=1848616&#msg_1848616
the use of alive-type components has the following advantage:
> Also the DTE during the shutdown can be avoided to use alive type
> components. The test ports of the alive components are not
> disconnected/unmapped when the component finished only when killed or
> the MTC terminated.
So the idea of this patch is to use alive-type components for all the
underlying infrastructure, such as the *_Emulation_CT starting from M3UA
to SCCP and further up the stack. This way, only the MTC and the
highest level of components (such as ConnHdlr) remain as normal
components.
The hope is that using more alive-type components in the lower protocol
layer emulations will reduce the probability of DTE during shutdown if
some message is received during the component shutdown after the MTC
has completed.

Otherwise it's impossible to run the CBSP test cases locally, because
the remote peer address in osmo-bsc gets set to '0.0.0.0', so indeed
it cannot establish connection to the server.

Fixes: OS#5351
Using the same IMSI in each test case makes it harder to correlate
subscriber connections in the SUT with particular test cases. A
good example is a problem described in OS#5337: some test cases
create dangling subscriber entries that never got released:
OsmoBSC# show subscriber all
IMSI TMSI Use
001019876543210 ffffffff 3 (3*paging-start)
001010000100001 ffffffff 1 (conn)
With this patch I am getting the following output:
OsmoBSC# show subscriber all
IMSI TMSI Use
001016017428234 ffffffff 1 (paging-start)
001014631230680 ffffffff 1 (paging-start)
001011161500382 ffffffff 1 (paging-start)
001010000100001 ffffffff 1 (conn)
so I was able to correlate the following test cases:
* (001016017428234) TC_lcs_loc_req_for_active_ms_ta_req,
* (001014631230680) TC_lcs_loc_req_for_active_ms_le_timeout2,
* (001011161500382) TC_cm_service_during_lcs_loc_req,
* (001010000100001) TC_no_msc.

This change fixes sporadic failures of TC_cm_serv_rej:
RAN Connection table not found by component TC_cm_serv_rej(2648)
BSC_Tests.ttcn:11106 BSC_Tests control part
BSC_Tests.ttcn:10550 TC_cm_serv_rej testcase
The reason is that sometimes a BSSAP/DTAP PDU (with CM Service Reject)
gets enqueued before the SUT has established an SCCP connection to the
virtual MSC. This causes a lookup error in the RAN connection table.
A simple solution would be to add a receive statement after calling
f_create_chan_and_exp(), like it's done everywhere else:
f_create_chan_and_exp();
BSSAP.receive(tr_BSSMAP_ComplL3); // <---
But a more general solution is to expect and receive this message in
f_create_chan_and_exp(), so we can reduce code duplication and make
the API more convinient. This is exactly what this change does.

So far all handover tests trigger handover via VTY command. This means
that any bugs introduced in measurement report handling and handover
target selection are by definition not caught.
Almost a year ago, fixing a handover oscillation bug for intra-BSC
handover introduced a segfault for inter-BSC handover targets, because
for those the target.bts is NULL. Show this bug.

As can be seen from ttcn3-bsc-test run #1565 on Jenkins [1], it may
happen that the VTY command requesting handover reaches the IUT earlier
than the SCCP 'SACK CC' message. In this case, the 'SUBSCR_CONN' FSM
remains in state 'WAIT_CC', so we get an error:
(bts=0,trx=0,ts=0,ss=0) (ARFCN 871) --> BTS 1 Manually triggering Handover from VTY
SUBSCR_CONN(msc0-conn204)[0x5633b2877af0]{WAIT_CC}: Received Event HANDOVER_START
SUBSCR_CONN(msc0-conn204)[0x5633b2877af0]{WAIT_CC}: Event HANDOVER_START not permitted
The easiest way to avoid this is to introduce and artificial delay
after the connection establishment and before triggering the handover.

The function f_TC_fh_params_set sets frequency hopping parameters. The
ARFCN is also part of those parameters. However, this function does not
set the respective band for the ARFCN that it configurs. This results in
an invalid setting at the BSC that might cause unexpected behavior.
Lets make sure we configure the band parameter correctly before setting
the ARFCN
