I used the construct like f_rnd_octstring(f_rnd_int(100)) in a number
of places to generate random-length packets with randomized length.
The problem I didn't realize is that f_rnd_int() of course can also
return '0', which would generate zero-length packets. This may be
permitted in some protocols, but it leads to problems e.g. when trying
to send a UDP packet of zero length (which the kernel will not do).
So let's introduce
* f_rnd_int_nonzero() for returning non-zero randomized integers
* f_rnd_octstring_rnd_len() for returning a random-length random payload
octet string
* replace all f_rnd_octstring(f_rnd_int()) call sites with the new
function.

Release of 256 tuns + threads takes quite a reasonable amount of time.
Let's increase the timeout since reset_all_state can take around 10
seconds sometimes.

We don't really act as rely agents in the emulation, so let's not
announce it.
Furthermore, this aids libfreediameter selecting proper routes, since it
seems to only underscore peers not matching the AppId if they are not
rely agents (see dont_send_if_no_common_app() in freeDiameter.git)

bsc-nat introduces a delay that will lead to failed tests, since the
reset attempt happens too early and times out, and the tests do not
retry.

According to 3GPP TS 48.008, section 3.2.1.71, the LCS QoS IE shall
be present if location of the target MS is requested and is optional
otherwise. Since [1], osmo-bsc started to check presence of this IE,
so let's add it to ts_BSSMAP_Perform_Location_Request.
Taking a chance, let's also add LCS Priority IE.

is apparently not 3GPP vendor specific.

TTCN-3 offers a very convinient way of matching an octetstring
against a record template (decoding target) on the fly, so that
there is no need to attempt decoding it manually beforehand.
This can be done by using the 'decmatch' keyword (see B.1.2.9).
Unfortunately, decmatch fails if an octetstring is longer than
the encoded variant of the decoding target (e.g. has padding).
Let's work this around by adding a 'padding' field, so during
decoding all remaining octets will be stored in it.

So far, osmo-bsc ignored the Codec List (MSC Preferred) in inter-BSC
incoming HO Request messages. Starting with osmo-bsc
I117cc29d6d11db77d160de654f43f5993db6ee21, a missing codec list on AoIP
causes incoming inter-BSC HO to fail, as it should (3GPP TS 48.008
indicates that a codec list shall be included on AoIP). To avoid test
fallout when merging above osmo-bsc patch, add a codec list to HO
Request on AoIP.

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.
