Daniel Willmann 0886215539 msc: Avoid race condition when setting osmux options via VTY
If the RAN_Emulation is started before the VTY reconfiguration we could
get a BSSMAP Reset/ResetAck with Osmux support advertised even though
the test expects it to be disabled (or vice versa).

Do the VTY configuration before starting the RAN_Emulation.

Fixes sporadic/load-related TTCN3 failures with message
"BSSMAP: Timeout waiting for RESET-ACK after sending RESET"
(e.g. TC_iu_and_mt_call_osmux, TC_iu_and_mo_sms in run +1567)

Neels Hofmeyr 731ddc558f bsc: fix TC_ho_into_this_bsc_a5_4
This test should be failing as it is, because A5/4 is not permitted in
the BSC's configuration! It only passed all this time because osmo-bsc
is/was/is going to have been flawed and just takes the Chosen Encryption
Algorithm IE as the basis for choosing an encryption algorithm. Instead
it should intersect the pemitted algos with the BSC config. It will soon
do that, and then this test would fail as it should have. After fixing
the BSC config for the test with this patch, we'll not see it failing in
the transition.

Neels Hofmeyr d23e8a0a76 bsc: improve encryption testing config TestHdlrEncrParams
Clean up: absorb pars.encr_exp_enc_alg into TestHdlrEncrParams as
pars.encr.alg_expect.

Remove the automagic encr alg choice from test procedures, instead put
all magic in the pars.encr configuration setup; like this all encr alg
values remain fixed through the tests, less confusing.

Add separate alg_chosen for BSSMAP: So far, we have only one algorithm
field for both the mask of permitted algorithms in the Encryption
Information IS and the Chosen Encryption Algorithm IE. However, in the
Chosen Enc Alg there must be only one bit set. Thus we cannot easily run
a test where more than one alg is permitted and where the BSSMAP Chosen
Enc Alg IE is involved.

We've recently come to realize that the Chosen Encryption Algorithm IE
may also be omitted from BSSMAP messages, in which case osmo-bsc should
still work. To be able to test BSSMAP messages with omitted Chosen
Encryption Algorithm, allow to set alg_chosen == omit.

Keep t_EncrParams() in a way that all current tests (that set only one
bit in alg_permitted) still run the same as they always did.

Add t_EncrParams2() for a proper template.
Add a convenience function to configure encryption testing.

Pau Espin b63d85f6a2 ggsn: Expect no linklocal-addr forwarding when testing open5gs
It's not really clear whether GTP should really be forwarding packets
with link-local address outside the tunnel. In theory the link-local
address should be used to communicate with the GGSN in order to get the
global link address, that's it. Running against open5gs it can be
observed that they are not forwarded, while osmo-ggsn forwards them
correctly.
Since it seems more like an implementation dependent detail, let's
accept any and adapt expectancies depending on what are we testing, this
way it ends up documented the current situation in case it ever changes
in the future.
