Pau Espin 8bd54cf77a library: Add templates to initialize CellId, RAI, LAI

Philipp Maier b76a279edf Osmocom_Gb_types: add RIM templates
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.

Harald Welte f20af41003 gbproxy: Introduce TC_overload
When the SGSN is sending an OVERLOAD message, we expect that to
propagate down to every BSS on the other side.

Harald Welte c0351d1015 gbproxy: Introduce TC_llc_discarded
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.

Harald Welte 8f66af1665 move f_gprs_tlli_{type,random} to Osmocom_Gb_Types
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.

Harald Welte 5339b2e372 BSSGP_Emulation: Support multiple PTP-BVC within one Entity
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.

Harald Welte 557c9f8cb8 move some key types from GSM_RR_Types to GSM_Types
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.

Pau Espin c03eb12b58 pcu: Test Downlink UNIT_DATA messages from SGSN containing IMSI IE
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.

Vadim Yanitskiy 7b2242157b PCU: also test GSGN originated PS/CS Paging containing TMSI
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).

Alexander Couzens c7dddbd7d0 Ensure BcdMccMnc is encoded as 24.008 10.5.5.15
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.
