With some real HW setups, there's no PCU (osmo-pcu) available locally,
for instance when using a sysmobts, or when using a nanoBTS. There's no
need to waste time and generate extra output by running this tests in
this case.
Furthermore, some tests seem to crash sometimes in that setup, probably
due to using invalid fd (-1):

MSC tests were unable to match odd-length digit strings in

This happens because the raw encoder for CallingPartyBCD_Number

constructing such a template in our own code to ensure that
we'll match the actual data received.

Instead of vaguely allowing any release messages to be present or not, exactly
pinpoint for each test case the exact release messages expected during lchan
release.
Related: an osmo-bsc change broke sending of RR Release messages, which was
utterly ignored and hence not caught by ttcn tests. That must not happen again.
I am not actually sure that these expectations are 100% correct; if errors
become apparent, we shall change the expectations in ttcn3 and then fix
osmo-bsc according to that.
Adjust f_expect_chan_rel() and callers,
and the Assignment procedures (as_assignment and f_establish_fully).

Allow osmo-bsc sending a Deact SACCH messages in most cases. Prepare the
ttcn3-bsc-tests to not break just because of those messages that will soon be
sent.
When releasing an lchan, it makes sense to Deactivate SACCH on it, if it was
ever active. So far osmo-bsc was fairly reluctant to send Deactivate SACCH, but
osmo-bsc Id3301df059582da2377ef82feae554e94fa42035 is about to change that.
In most test cases, Deact SACCH are still optional, but in one case, the
current missing Deact SACCH will introduce a test failure: in the 'interleave'
of BSC_Tests.TC_ho_out_fail_no_ho_detect.
As soon as abovementioned osmo-bsc patch is merged, the test will pass again.
Also, as soon as Ibc64058f1e214bea585f4e8dcb66f3df8ead3845 is merged here, the
bsc tests will properly ensure whether Deact SACCH is sent or not in all tests.

Receive RR Release messages if they happen during lchan release. Add RR Release
to the alt{}s in both f_expect_chan_rel() to cover a whole bunch of test cases,
and in f_tc_ho_out_fail_no_ho_detect() which has its own release expectations.
Before this, RR Release messages would typically be lost in the RSL.clear
recently removed by Ie1be30c3f109dda8c58c523df508211f8e20aad3.
However, I still expect tests to pass after this, since the current osmo-bsc
master has a bug that omits RR Release messages (since [1]).
By applying this patch, both the buggy osmo-bsc (omitting RR Release) and the
fix of that [2] should pass the BSC tests. So far by accepting whatever comes
along, and not complaining if it doesn't come along.
A subsequent patch will more precisely ensure that exactly the expected
messages will be sent by osmo-bsc (Ibc64058f1e214bea585f4e8dcb66f3df8ead3845).

When we're expecting release, it can be non-deterministic / timing dependent to
flush the RSL queue. Particularly the RR Release message is typically already
in the queue when f_expect_chan_rel() is called and would be lost.
It turns out that none of the current callers need the flush feature.
If a test needs it, we can add a separate f_rsl_flush() function and call that,
no need to clutter up the f_expect_chan_rel() argument list. I had such
function but found that no caller needs it, so dropped it.

Matching the CONFIG prompt using implicit '\w+(*)' pattern is
a bad idea, because it can actually match almost anything:
- 'OsmoBlaBla(config)# ',
- 'OsmoBlaBla(config) ',
- 'OsmoBlaBla> ',
- 'Mahlzeit'!
One problem is that the parentheses are interpreted as a matching
operator (which is used to group an expression), so they should
have been escaped by '\'. Another problem is that this pattern
is not complete, because '\# ' is missing. Let's fix this!

This function can now be called from anywhere to try and safely shutdown
a testcase. It is not optimal as we can't call "all component.stop" from
outside the mtc, but without any proper and orderly shutdown handling of
all our emulation components I believe this is the best we can do.
To use it:
import from Misc_Helpers all;
in your module and then call
Misc_Helpers.f_shutdown(__BFILE__, __LINE__);
You can also pass the function a verdict and a message and it will take care
of calling setverdict, but beware of the following:
While setverdict would accept any number of arguments as log message
and convert them to a log string f_shutdown expects one charstring.
It's possible to use the log2str function to use the log arguments in
setverdict for f_shutdown, for example
setverdict(fail, "Template didn't match: ", tmpl_foo);
would become
Misc_Helpers.f_shutdown(__BFILE__, __LINE__, fail, log2str("Template didn't match: ", tmpl_foo));

This new test sends the header in one burst, followed by the
payload which is transmitted byte-per-byte.
The test uses an ID REQ message. If acting as a server, the test
can expect an ID RESP message. However, if acting as a client, the
server will close the connection when it receives the ID REQ.
The CTRL interface port on the BSC does not close the connection in
