Harald Welte 9b461a94a3 sgsn+pcu: Port suspend/resume cases to new BSSGP_CT:GLOBAL port
For 12+ days, suspend/resume related SGSN + PCU TTCN3 tets have been failing.

It was the introduction of the BSSGP_CT:GLOBAL test port in
I40d973d80709f5d56f59247e8647b52754f09bc8 +
I805372f3024a0ec2491a24422e02c0bc6dc669d2 which caused the related PDUs
now to no longer show up where they used to.

Harald Welte 4d112c926c BSSGP_Emulation: Allow a "CreateCb" to handle unknown inbound TLLI
The existing BSSGP Code assumed that the TLLIs were always known "a
priori" by the test case.  With the newly-introduced create_cb,
the user can provide a function to handle any incoming messages for an
unknown TLLL.  The default handler behaves like before: fail +
terminate.

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.

This adds a NS_Provider_FR which interfaces between FrameRelay_Emulation

Harald Welte 60408e3f57 Don't map NS_Emulation_CT:NSCP anymore
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.

Harald Welte 013d65af1e NS_Emulation: Introduce NS_Provider underneath NS_Emulation
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.

now depends on RLCMAC_*, creating a long chain of dependencies.

Pau Espin ce571b5cc4 sgsn: Introduce test TC_attach_req_id_req_ra_update
The scenario in this test triggers a crash in osmo-sgsn fixed by
osmo-sgsn.git I64fa5cf1b427d3abb99e553e584897261a827ce6.

With that osmo-sgsn patch applied, the process doesn't crash anymore but
the test still fails due to an XID message being sent with a new
yet-not-seen-by-ttcn3 TLLI and as a result TTCN3 BSSGP_Emulation fails:
BSSGP_Emulation.ttcn:390 setverdict(fail): none -> fail reason: "Couldn't find Component for TLLI 'FE791757'O", new component reason: "Couldn't find Component for TLLI 'FE791757'O"

Other than that, the test runs fine. It still needs to be clarified
whether the new TLLI sent by osmo-sgsn is expected and test needs to be
fixed, or whether it's an sgsn bug.
