Report: in inter-BSC incoming handover, when the MSC omits the Chosen
Encryption Algorithm IE in the Handover Request message, then osmo-bsc
starts an unencrypted lchan even if A5/0 is not permitted.
This test verifies that the Encryption Information is present in the
Channel Activation when the Chosen Enc Alg is omitted.

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.

The existing test TC_pdp46_act_deact_gtpu_access_wrong_global_saddr_ipv6
was wrong, because the global address was being finally encoded as a

simlar to the ones used to test IPv6-only APNs.

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.

This patch implements a new mode of operation, which allows to
have direct communication between the emulation component and
the other component connected via the 'DIAMETER_UNIT' port.
This eliminates the need to have dedicated components for each
IMSI, what is not necessarily needed in some specific cases.

IPA_Emulation component was marked with the "alive" type recently, in
order to avoid race conditions leading to errors during tear down of the
test.
It turns out, the way "alive" keeps the component alive is by means of
not closing the sockets when the component is stopped. As a result,
TC_rsl_drop_counter test stopped working properly because it was
specting a TCP FIN to be sent to osmo-bsc when the component was
stopped.
In order to fix it, add a new CFG port to the IPA_Emulation component on
which one can operate. Add a a new method to tell the component to close
the socket.
Then, put that in BSC_Tests into a function which was actually unsued
until now, and use it in the test in order to have the specific logic
enclosed in a function helper.
