reasons:
* TC_assignment_fr_a5_4() runs an unusual sequence of messages: it first
fully assigns an lchan, and after that sends a Cipher Mode Command.
Usually, the ciphering happens as part of attaching (Compl L3).
The new test TC_assignment_fr_a5_not_sup() does the ciphering in the
usual sequence, and properly expects a Cipher Mode Reject.
* TC_assignment_fr_a5_4 means to ask for an *unsupported* encryption
algo. Since we are going to introduce A5/4 support shortly, we'll need
to free up this name, for a successful A5/4 encryption test.
New test TC_assignment_fr_a5_not_sup() asks for A5/5 encryption, which
is not supported.

Since recently, we do have NOPE indications in the virtual Um
environment. Somehow this broke test cases for the MS power
control. Releasing the channel makes everything work again.

This adds a few tests that ensure that the encryption algorithm dynamically chosen is
1) one actually supported by both the sgsn and the UE
2) the strongest one available both have in common

RAW_NS used previous a single TTCN3 port for a single UDP port
(source/listen side).
This has the limitation that only a single NSVC could be tested for a
local UDP port. However SNS tests require multiple NSVCs over a single UDP port.
NS_Provider_IPL4 already supports multiple NSVCs for the NS_Emulation.
Extend the support in NS_Provider_IPL4 to also allow RAW_NS to use
multiple NSVCs.

The function didn't wait to receive the 2 messages from the BSC. As a
result, they may have arrived while tearing down the test components
shortly after exiting the function and provoke a Dynamic Test Error
while pushing the messages up the stack since some of the stack layers
may already be unavailable.
Test TC_ho_out_of_this_bsc() workarounded this by using a f_sleep(1),
but TC_srvcc_eutran_to_geran_ho_out() didn't, making it fail sometimes.

Recent changes [1] to osmo-bts make it periodically send the
RF RESource INDication messages for each transceiver over the
A-bis/RSL. These messages block the queue of 'RSL_CCHAN' port
and make the paging related test cases fail. Ignore them.

During f_create_chan_and_exp() (part of f_establish_fully()), announce
the BSSAP L3 expectation before activating the lchan.
In RSL_Emulation f_chan_est(), we go through Chan Request, Channel Act
and Immediate Assignment followed by EST IND. Right after that, osmo-bsc
sends a Complete Layer 3 on BSSAP. But in f_create_chan_and_exp(), we
only create the expectation of the BSSAP right after the call to
f_chan_est(), i.e. only after sending the EST IND. So far it was always
juuust in time to work, but when I added a little check to the end of
f_chan_est(), or alternatively an f_sleep(0.2), then BSC tests always
fail with:
Test case TC_reassignment_fr finished. Verdict: fail reason: Couldn't find Expect for incoming connection { [...] pdu := { bssmap := { completeLayer3Information... }
With the BSSAP expectation done first, this error is avoided.

The testcase TC_one_crcx_loopback_rtp_implicit triggers a bug in older
osmo-mgw version that eventually leads into a crash of osmo-mgw. This
also means that all tests after TC_one_crcx_loopback_rtp_implicit will
also fail. Lets move TC_one_crcx_loopback_rtp_implicit to the end of the
control section to postpone the crash to the very end of the testrun.

Unfortunately, trxcon does not support handling more than one
connection in parallel. If there is already one connection
established, it would reject all other connection attempts.
This causes an error in f_handler_init(). As a quick hack,
let's allow running BTS_Tests.ConnHdlr components without
establishing L1CTL connections at all.

If an SGSN in a pool is down we expect the messages to instead be sent
to a different SGSN in the pool. That SGSN will not necessarily know
what to do with those messages, but it should )implicitly) detach that
UE so that it can reattach at the new SGSN. Otherwise UEs on a failed
SGSN would simply stop working as the messages would never be forwarded
anywhere.
This test also adjusts the NS timers so the failed NSVCs are detected
faster.
