There's also DL_ACK_NACK message for which a template will be introduced
soon, so let's rename and fix typos/wrong descriptions to avoid
confusion later.

This change is a step towards getting rid of the old test case
infrastructure. Note that a call to f_bssgp_establish() is moved
out of f_init_bssgp() to the test case's body.

Both 't_IMM_ASS_TBF_DL' and 't_RR_IMM_ASS_TBF_DL' templates were
introduced for a specific task - matching Packet Immediate
Assignment (Downlink TBF) by TLLI.
In the upcoming changes we will also need to match Uplink TBF
assignment, and more generic fields such as Timing Advance.
Let's add a generic template for Packet Immediate Assignment
and allow passing IaRestOctets as a parameter.

According to 3GPP TS 44.018, section 10.5.2.16, IA Rest Octets IE
starting with 'HH' bits may contain one of the following CSN.1
encoded components:
7 6 5 4 3 2 1 0 Bit Numbers
H H 0 0 . . . . Packet Uplink Assignment
H H 0 1 . . . . Packet Downlink Assignment
H H 1 . . . . . Second Part Packet Assignment
We already have (partial) support for the first two, while the
last type has not been supported so far. Let's add it.
Also, this change introduces several templates for IA Rest Octets
IE and some of its components mentioned above. This would allow
us to abstract the API users from dealing with further changes,
e.g. adding a coding attribute 'CSN.1 L/H' and missing fields.

Make the decoding level (BSSGP, LLC, SNDCP, L3) configurable, so the
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
of f_send_bssgp_dec.
I have verified, that all testsuites using the BSSGP Emulation (SGSN,
PCU, PCU-SNS) are still working with this patch.

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.

Some of our files didn't have a copyright notice at all, let's add
it. Also, update the notices in other files and ensure a SPDX
identifier is present in all but the most trivial files.

The PCU is supposed to forward any RR SUSPEND received by the BTS
on dedicated channels and pass it to the SGSN via BSSGP. This provides
knowledge to the SGSN that the MS is not reachable via PS/TBF anymore
until it completes its CC dedicated mode transaction and RESUMEs.

Implement a basic paging test for the PCU, which is passing for paging
via TMSI (but only if osmo-pcu is started after the test is started).
Previously, this test code amounted to a debugging loop which
never terminated.

* remove unused parameters
* add expected results
* use control for default test execution
* only tests which could (in theory) pass are left in control
Previously generic control had some tests which never called
"setverdict(pass)" which means they would always fail. Such tests might
be useful during development but should not be part of test set executed
by default.

The NS_Emulation has configuration values hardcoded or bound
to module parameters which prevents multiple instances.
Replace the module parameter based configuration with configuration
given when starting the NS_Emaulation.

Call mtc.stop after setverdict(fail), add reasons to most failures and
fail with verdict error for internal errors.

osmo-pcu discards PAGING-PS messages unless received on the
signalling BVCI 0. The BVCI value must be set to zero both
in the NS header and the BSSGP header. Create new ports between
the PCU_Test components which the TC_paging test case can use
to ensure that both layers send frames with BVCI value of zero.
This does not make PCU_Tests.tc_paging work yet, however the PS
paging request is now processed by osmo-pcu rather than discarded.
