The g_handle_rx_alive allows ignoring any ALIVE PDUs when
using f_exp_ns().
This improves the stability as the ALIVE and BVC-RESET
can come in any order.

There shouldn't any unconfigured NSVC after the configuration phase. The unconfigured
NSVC is used in the SNS configuration phase and must be removed when the configuration
is done and the NSVC is included in the configuration.

All BSS-originated BVC-Reset for PTP BVC must contain a Cell Identifier.
This test is not respecting that rule
libosmogb correctly detects this and discards the RESET, which is not
what is intended here:

Previous RAW_NS only supported NS over UDP because
it handled the UDP connection on it's own.
Because of this there was no cleanup function for the tests
because no virtual component were started.
Using the new NS_Provider allows to use the same tests over
UDP and FR with no changes.

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).

When sending the SNS ADD in the test case the ip/port to add must be different
from the current NSVCs.

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

With PCUIF 10 the remote can be IPv4 or IPv6.
Add all missing parts including SNS IPv6 elements,
the support to omit IPv4 elements and a PCU_Tests_SNSv6.cfg
configuration to run all tests with 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.
