This was created during code review towards some upcoming fix for
OS#2736. However, it's not really related to that.

This timer is started when a channel is allocated with an IMMEDIATE
ASSIGNMENT message. It is stopped when the MS has correctly seized the
channel. Ever since the early days of development we were using a very
long timeout to be on the safe side. However, in production networks
this is a terrible waste of resources, as we will occupy 10s worth
of air-time on one of our channels for each RACH request we receive.
The only scenarios where you might need something absurdly high as 10s
would be if you have 8s of RTT between your BTS and the BSC.

Previously we simply omitted SI2ter Rest Octets which is spec violation
which lead to 'Malformed Packet' error in Wireshark RSL dissector. Fix
this by generating empty 'no rest octets' with proper padding. Adjust
test output accordingly.

* check GPRS state: if GPRS is enabled for the BTS but NSE, CELL or both
NSVC are locked than report it as degraded
* check TRX usability: use already available function to check that TRX
is actually usable when reporting OML status via CTRL
* fix tests linking: libbsc is using gsm48_create_mm_serv_rej() which is
defined in libcommon-cs but neither libbsc itself nor tests using it
are actually linked against libcommon-cs

This is left over from the OsmoNITB days. We're defining and allocating
these MSC counters, but never actually using them. This also means that
the automatic counter export will list them, raising the expectation at
users that such counters could be used in OsmoBSC.
Let's remove them. They are in OsmoMSC, but not OsmoBSC.

In more recent versions of libosmocore, we are converting any '.'
in [rate] counter names to ':' to avoid clashes with the special
meaning of '.' in the CTRL interface. Let's avoid any conversion
and use the proper name already here.
This also changes the codec_foo counters to codec:foo to follow the
notation of other counters.

We used to have a lot of counters only globlly per BSC, but they're
much more useful on a per-BTS level.

The snprintf() that is used to compose the fsm name on an assignment
request may cause a silent failure. The buffer is large enough to
take the string under all circumstances. If snprintf() fails, this
would mean we have some other serious problem.
use OSMO_ASSERT in case the snprintf() fails, so the failure
gets noticed.

In the beginning of the CRCX phase for the network does not distinguish

the functions mgcp_timeslot_to_endpoint() and rtp_calculate_port()
which are used to calculate the port in the sccp-lite / non AoIP
case are part of libosmo-legacy-mgcp. Unfortunately libosmo-mgcp
and libosmo-legacy-mgcp cause problems when used at the same
time.
Replace the functions mgcp_timeslot_to_endpoint() and rtp_calculate_port()
with a local helper function.

Prepare for a future change that accesses bts->network during gsm_bts_alloc().
Currently, gsm_bts_alloc() takes a ctx parameter, and gsm_bts_alloc_register()
then gets the gsm_network pointer and sets bts->network to it. All callers
anyway pass gsm_network as ctx to gsm_bts_alloc(), and anything else would not
make sense anyway. So enforce passing exactly gsm_network to gsm_bts_alloc()
and already set the bts->network pointer from there.

In state prior to this patch, "3G Early Classmark Sending Restriction"
bit in SI3 rest octets was always set to H, which is a sane default as
the policy to send the information is then controlled by "Early
Classmark Sending Control" bit in the same octet.
However, it seems Quortus SoftCore can have some issues decoding the
option, so let's add a vty cmd to be able to disable it for those
having any issues.

According to documentation (and personal experience), AM_PATH_PYTHON
selects the highest version of python, no matter if major version is
different, which means if both python2 and 3 are available, 3 will be
chosen an PYTHON will point to "/.../python" which is python3. Apparently,
the macro cannot be easily used to pick highest python2 version.
As {vty,ctrl}_test_runner.py require python2 and are incompatible with
python3, let's instead rely on the system having a "python2" binary
available, which is the case in most distros.

First off, there are "global" and "local" IMSI black/whitelist levels:
"global" "local"
VTY 'bsc' 'msc' for osmo-bsc
VTY 'nat' 'bsc' for osmo-bsc_nat
Both in osmo-bsc and osmo-bsc-nat, the "global" IMSI filter so far completely
ignores all 'imsi-allow' rules it may contain. A comment in imsi_allow()
proclaims actions that are missing in the code. Notably, in our example config
osmo-bsc_nat.cfg, there is an imsi-allow on the 'nat' level, which with the
code before this patch cannot have been effective in any way.
Furthermore, on the "local" level the order is to check imsi-allow first, and
imsi-deny after that. The comment says to do that in reverse order on the
"global" level. There is no apparent reason for reversing.
Add evaluation of imsi-allow directives on the "global" level, i.e. 'bsc' in
osmo-bsc and 'nat' in osmo-bsc-nat, in the same order as on "local" level, to
avoid confusion. Swap the comment to be consistent.
Before this patch, to have effective imsi-allow, this config would be necessary
for osmo-bsc:
bsc
access-list acl imsi-allow 999999999999999
access-list acl imsi-allow 9017.*
access-list acl imsi-deny .*
msc 0
access-list-name acl
...
msc 1
access-list-name acl
...
With this patch, imsi-allow also works on the "global" level:
bsc
access-list acl imsi-allow 999999999999999
access-list acl imsi-allow 9017.*
access-list acl imsi-deny .*
access-list-name acl
msc 0
...
msc 1
...

OSMO-FSMs already have such a feature there is no need for an
