We don't want to pass the test or return from this function before
receiving a RAU accept. With Iu we expect a Security Mode
Command/Complete before the routing area is updated, but we do want to
wait for the actual RAU Accept or fail when receiving a RAU Reject.

The scenario in this test triggers a crash in osmo-sgsn fixed by
osmo-sgsn.git I64fa5cf1b427d3abb99e553e584897261a827ce6.
With that osmo-sgsn patch applied, the process doesn't crash anymore but
the test still fails due to an XID message being sent with a new
yet-not-seen-by-ttcn3 TLLI and as a result TTCN3 BSSGP_Emulation fails:
BSSGP_Emulation.ttcn:390 setverdict(fail): none -> fail reason: "Couldn't find Component for TLLI 'FE791757'O", new component reason: "Couldn't find Component for TLLI 'FE791757'O"
Other than that, the test runs fine. It still needs to be clarified
whether the new TLLI sent by osmo-sgsn is expected and test needs to be
fixed, or whether it's an sgsn bug.

existing PCU tests, that expect messages only decoded to the BSSGP
level, can pass again. Move the SNDCP decoding in f_dec_bssgp above the
L3 decoding, so f_dec_bssgp goes through the layers in the reverse order

It originally seemed like a great idea to define a custom record
which aggregates the decoded BSSGP, LLC, L3 and/or SNDCP and passes
it to the individual ConnHdlr. However, particularly with testcase
interoperability for IuPS in mind, this seems bogus. Also, we
never really took advantage of this.
Let's now decode as far as we can decode any PDU, and then send the
decoded version of that PDU via the ports between the BSSGP_Emulation
and the ConnHdlr component.

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));

Pass the CTRL_DETECT_CONNECTION_ESTABLISHMENT_RESULT parameter to

into an error handling path if they are started while the osmo-*
program they want to connect on VTY is not running.

into a VTY connection failure the subsequent test would get
stuck forever in a map() call on the VTY TELNET port.
Teach the function f_vty_wait_for_prompt() about connection

represents the socket file descriptor for the telnet connection.
This case was not handled by the previous change made in
commit cb111b21ab. As a result,
BSC tests started failing with "VTY Timeout for prompt" because
the alt-statement in f_vty_wait_for_prompt() would not progress
past the integer sitting on the VTY port's receive queue.
