This port is used for sending/receiving RIM related BSSGP messages. It
exists once per BSSGP_CT Component (i.e. once per NSE), as RIM is global
for the entire NSE.

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

the existing ordering of altsteps unfortunately caused some
receive clauses never to be hit, as they are only in the default
altstep, while more generic receive clauses are already in the
state-specific altsteps.
Let's introduce an as_allstate_pre() and an as_allstate_post() to
solve this ordering problem.

We recently introduced a MGMT port in the per-BVC component for the
PTP BVC. Let's add this also to the signaling BVC.
Change-Id: I24df4cb290c9f9dc1a7398994af101711f12d42e
This notifies the user via the MGMT port about the fact that an inbound
BVC-RESET procedure just happened.

We need to change to BLOCKED local state in order to activate
the altstep which handles the inbound BVC-RESET-ACK.
Change-Id: I32ede586f0977b7d96af9fe3ea5fae485184ea98
We cannot handle this in as_ptp_allstate(), as the respective clauses
are never hit: In as_ptp_unblocked() we broadcast all BSSGP messages
without a TLLI, "hiding" the BVC-RESET handling.

The per-NSE BSSGP_CT gets a new GLOBAL port which is used for procedures
that are not specific to one BVC, such as the SUSPEND/RESUME related
PDUs, which all are on the signalling BVC without any BVCI in the BSSGP.

The primitive normally only contains NSE + BVCI, but in a tester
we actually want to verify which NS-VC a given message has arrived on,
and hence it makes sense to add the NSVCI, too.

This port can (optionally) be connected to, and it will receive
state change notifications as well as permit the user to block/unblock
and reset the specific PTP BVC.

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.

The Load Sharing Function distributes traffic among all unblocked NS-VC
within a NS-VCG. The sharing is done based on a LSP (Link Selector
Parameter) which is passed with the NS-UNITDATA.req primitive from BSSGP
to NS. Details are implementation specific, but NS must ensure that all
traffic of one LSP is always sent through the same NS-VC, as long as
that NS-VC is alive/unblocked.
We use the LSP as follows:
* Signaling BVC always only uses lsp 0
* PTP BVC messages unrelated to user straffic use a per-BVC static LSP,
which is the BVCI
* User traffic can set whatever LSP it wants
* NS keeps an array of NSVCs currently unblocked and uses the LSP modulo
the array size as an index into it

In case of a NS-VCG with multiple NS-VC, we must BVC-RESET only when the
first NS-VC becomes unblocked, i.e. as soon as we have any connection
to the peer at all. Whether we have further additional links doesn't
matter, at least not in the sense that all state should be reset.

This is something we need to simulate more complex scenarios,
particularly in the context of frame relay.

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 is required by the spec, and implemented libosmocore since

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

We always used to include the CellID IE, but 3GPP TS 48.018 is
actually quite specific about when it should be present and when not.
