The template set we use for testing the GB (BSSGB) interface on
osmo-sgsn and osmo-pcu lacks templates to generate RIM (ran information
management) messages. The records and unions are already specified in
BSSGP_Types.ttcn, we just need to form templates in order to be able to
use them.

When the SGSN is sending an OVERLOAD message, we expect that to
propagate down to every BSS on the other side.

This tests the LLC-DISCARDED message, which relates to a BVCI but
is itself sent on BVCI=0. We expect it transparently passes from BSS
to SGSN.

Those functions don't depend on any L3 specific data structurs, and
it is not a good idea to burden every user with having to impot all
of a 2G/3G Layer3 just to generate some hexstring identifiers.

With PCUIF 10 the remote can be IPv4 or IPv6.
Add all missing parts including SNS IPv6 elements,
the support to omit IPv4 elements and a PCU_Tests_SNSv6.cfg
configuration to run all tests with IPv6

Those can help to match if messages meet certain constraints stipulated
in the BSSGP specification.

The existing BSSGP_Emulation is built around the assumption that every
instance of BSSGP_Emulation only servers one signaling-BVC and one
PTP-BVC. While this is true for osmo-pcu at this point (BTS-colocated
PCU), other BSS/PCU implementations differ.
In general, there can always be any number of PTP BVC (one per cell)
next to the signaling BVC (one per BSS). Let's represent this in
BSSGP_Emulation so we can create more comprehensive tests.

This in turn means Osmocom_Gb_Types doesn't need to depend on
GSM_RR_Types anymore, which is particularly ugly as the latter
now depends on RLCMAC_*, creating a long chain of dependencies.

osmo-pcu.git 0052051c07af63da98137c9f8e3b3119642eb587 introduced a bug
(fixed in 1d68cdff928f32941aff36c70e4543203c283d15) where no MS could
GMM attach to the network, but no test showed the issue.
This couple test verifies both correct behavior and also ensures wrong
IMSI is detected and reported.

This additional couple of test cases reveals several bugs:
1) the IUT encodes a erroneous RR Paging Request message
containing P-TMSI, so TITAN fails to decode it;
2) the IUT prints an invalid P-TMSI in its log output
due to load of misaligned address (found by UBSan).

PCU is using BcdMccMnc as it's encoded as 24.008.
But SGSN code is using it as it would be byte by byte
sorted.

This code had been intended to be used, but commented out, and
never really been completed or tested.

When we started out, Ericsson hadn't released yet their NS and BSSGP
modules. Let's port our logic over to their encoder/decoders, as they
are more complete (but less regular / more difficult to use).
