Harald Welte 90f1974fb0 NS_Emulation: Support multiple NS-VC within one NSE (NS-VCG) 
This is something we need to simulate more complex scenarios,
particularly in the context of frame relay.

Harald Welte e97e3af203 PCU_Tests_{NS,SNS}: Fix our expectations regarding CellID in BVC-RESET 
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.

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 23e274919d PCU_Tests_NS: Fix our expectations regarding CellID presence/absence 
This is required by the spec, and implemented libosmocore since
Change-Id Ie87820537d6d616da4fd4bbf73eab06e28fda5e1

So let's change our test expectations.  Meanwhile, introduce
mp_tolerate_bvc_reset_cellid for working around the bug in 'latest'.

Alexander Couzens ad70991d51 RAW_NS: remove usage of mp_gb_cfg 
RAW_NS uses module parameter from SGSN_Components. To decouple
RAW_NS from SGSN_Component pass the cell_id via a function argument.

Alexander Couzens 355ab56a24 PCU_Tests_NS: allow an UNBLOCK message to arrive before ALIVE 
The ALIVE PDU does not have to be sent before an UNBLOCK message.
Ignore UNBLOCK messages in cases a single ALIVE is expected.

According to TS 48.016 v5.2.0, 7.4:
"Upon successful completion of an NS-VC reset procedure,
a BSS (or SGSN) shall start timer Tns-test, then [..]"
The ALIVE should arive Tns-test after the reset procedure (typ. 1s-60s).

Pau Espin 8dd59fba5e pcu: Rename PCU*RAW* content to PCU 
Basically what's done here:
* mv PCU_Tests_RAW${suffix}.ttcn -> PCU_Tests${suffix}.ttcn
* mv PCUIF_RAW_Components.ttcn -> PCUIF_Components.ttcn
* Change module names according to file names and fix all references in
  code and configuration.
