ARFCNs are allocated sequentially, so that conversion between
arfcn<->trx_nr is easily done.
Some helper functions are introduced to be able to submit and expect
messages on a given TRX+TS, which is required for setups with several
TRX and PDCH-enabled TS different than the default. These new APIs
will be used in PCU_Tests.ttcn in subsequent patches.

The change introduces three new test cases:
- TC_paging_cs_multi_ms_imsi,
- TC_paging_cs_multi_ms_tmsi,
- TC_paging_cs_multi_ms_imsi_tmsi.
Each of these establishes 56 Uplink TBFs, and then enqueues 56 CS
PAGING requests from the SGSN side. The main idea is to verify
encoding and compositing of the paging MIs in PACCH massages.

In TTCN-3, array assumes a fixed number of elements. A 'record of'
type is more like a 'list' in Python, so let's call it this way.

older versions of osmo-pcu were broken and were only allocating TBFs in
the first TRX available. This is now fixed and hence osmo-pcu tries
better to allocate TBFs across different TRX. That's why the test needs
to be fixed to set up only 1 TRX in order to run into the same scenario.

With PCUIF 10 the remote can be IPv4 or IPv6.

The BVC-RESET / BVC-RESEt-ACK follow a set of rules:
* Signaling BVCI=0 never has a CellId in BVC-RESET nor BVC-RESET-ACK
* Any BVC-RESET or BVC-RESET ack in BSS->SGSN direction must have CellID
* Any BVC-RESET or BVC-RESET ack in SGSN->BSS direction must NOT have CellID
Let's adjust our test expectations accordingly.
This will break tests against "latest", but the amount of work-arounds
needed in this code outweighs the benefit.

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 adds a NS_Provider_FR which interfaces between FrameRelay_Emulation
and NS_Emulation. Include support for it only if enabled at compile
time to avoid pulling in a dependency on the FrameRelay stack for every
user of NS_Emulation.

Both osmo-bts and osmo-pcu are switching to PCUIFv10 soon, so let's
use the new version by default. For older (latest) IUT versions
not supporting PCUIFv10, one would need to override this module
parameter in {BTS,PCU}_Tests.cfg.

NS_Emulation_CT:NSCP used to be a NS_CODEC_PT, which is a translation
port on top of the IPL4asp. Such ports need to be mapped to a system
port at start-up.
However, in I4d0b7ad0ed9447a038dd3eeee2b975146d10fba0 we introduced
a new underlying component called NS_Provider. Hence, NSCP is actually
connected to that underlying component, and no longer mapped.
The corresponding change in pcu/SGSN_Components.ttcn and sgsn/SGSN_Tests.ttcn
has unfortunately been missed in the above-mentioned change. Fix that.

This is a step to prepare the NS_Emulation for operating on top of
Frame Relay, not just UDP/IP. We replace the NS_CodecPort (mapping to
a IPL4asp) with a newly introduced NS_Provider_CT, specifically a
NS_Provider_IPL4_CT.
This change removes any IP specific bits from NS_Emulation and moves
it into the newly-created NS_ProvideR_IPL4.
