To avoid a dynamic test case error we need to prevent messages arriving on
unconnected ports. Waiting some time before stopping components ensures that
any messages "in flight" will be delivered to the port before the component
is shutdown and disconnected.
It would be far nicer to mark a testresult "final" and ignore such
errors on shutdown, but I don't think it's possible in TTCN3.
This fixes TC_fc_bvc on my laptop which consistently failed with a DTE
before.

The port receive operation only considers the first message in the
queue. We need to drain unrelated status/reset messages, such as those
from PTP BVCs, otherwise the test never completes and times out.

Ensure that a suspend/resume was sent before sending the *_(N)ACK. In
reality these can only happen together and our TLLI cache removes
the entries after it sees the corresponding (N)ACK so it will not
forward the second message.

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.

Using "master" doesn't really work as the local master branch already
exists even if we change the 'remote' to a different URL, see

Since Idb453fc894584ccf4f5f8b45a24421db958e9478, osmo-bsc does send
ip.access specific Measurement Pre-Processing Defaults. This message
currently blocks the 'alt' statement in f_recv_next_si1(), so all
test cases calling it fail due to the guard timeout.
What's even worse, both TC_si_acc_rotate() and TC_si_acc_ramp_rotate()
dynamically configure the IUT in order to re-generate and send System
Information messages periodically. If any of them fails prematurely,
the related configuration parameters would remain active, so the IUT
would continue sending System Information messages, causing failures
in subsequent test cases.
Let's simply ignore all unmatched messages in the 'alt' statement.

There is a global boolean flag that would make f_init() return

Calling f_shutdown_helper() in f_tc_chan_rel_rr_cause() leads to
premature test case termination, so only one out of 6 cause values

The emulation of an SGSN with SNS was incomplete. The SNS
procedure was completed. However the NSVCs didn't moved
into an unblocked state.
Also sending a NS_ALIVE at the beginning is wrong.

The BVC-RESETs are a little bit more complicated. The PCU will send
a BVC-RESET after the NSE become available.
Ensure the RESET is received and ignored so there is no race condition
if both sides send a BVC-RESET at the same time.
The test case TC_sns_1c1u_so_bvc_reset is still failing because the PCU can't
handle BVC-RESETs properly (both PTP and signalling).

Recent commit 7d0f9a0ec383fcfca934731bd6979b6be6629c90 in osmo-pcu.git
fixed situation where lots of unneeded LLC UI dummy frames where being
sent. As a result, osmo-pcu correctly counts less dl rlcmac payload
bytes being sent, so we must adjust our test expectancies.

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

I805372f3024a0ec2491a24422e02c0bc6dc669d2 which caused the related PDUs
now to no longer show up where they used to.

We did have a guard time in each ConnHdlr, but not in the MTC (test_CT).
However, we do have tests that don't use any ConnHdlr, and those were so
far ran without a guard timeout. Fix that.

This way it's more obvious that it refers to the PTP BVC, like we
already use PCU_SIG and SGSN_SIG for the signaling BVCs.
