This patch introduces protocol codecs for the HNBAP, RUA and RANAP
protocols, which is mandatory for testing IuCS, IuPS or Iuh in
the future.
As Eclipse TITAN ASN.1 only supports the BER codec and the above
protocols all use APER, we need to use an external transcoder from
APER to BER and vice-versa. This was implemented using a proprietary
ASN.1 compiler / trnaslator which sysmocom is packaging as
libfftranscode, which is made available as binary package
for Debian 9 at https://ftp.osmocom.org/binaries/libfftranscode/

The RAN_Emulation currently unconditionally provides BSSAP and MGCP support.
Let's re-structure the code so that support for those protocols is now
possible to enable/disable at compile time.
This patch is in preparation of introducing RANAP support in RAN_Emulation.

This test case reproduces a bug in OsmoSGSN where it would crash
as a result to sending LLC NULL frames.

When running tests with real hardware it is important to wait for some
time (3 sec. should be enough) before exiting f_init(). This is to
ensure that the BTS supplies a stable carrier before the test proceeds.

The default value for the module parameter mp_ipa_up_timeout is set to
10 sec. Given that the sysmobts needs around 10-11 sec. to perform one
restart cycle this is to low and causes tests to fail occasionally. Lets
increase the default value to 15 sec to get reliable.

According to 3GPP TS 04.60, section 11.2.5a, the extended (11-bit)
Access Burst on RACH/PRACH is used by the MS to indicate its EGPRS
capability. One of the alternative synch. sequences (see 3GPP TS
05.02, TS1 and TS2) shall be used.
Add a test case to verify extended (11-bit) RACH decoding.

This allows to start ConnHdlr on specific RAN connections, i.e.
on different emulated BSCs (and soon RNCs).

So far, BSSMAP_Emulation supported only a transport over BSSMAP.
However, we soon intend to merge support for RANAP in order to
simulate RANAP/Iu connections as well as BSSMAP. Let's start
by renaming some of the existing types/functions/ports/modules
without introducing any functional changes just yet.

PCU is using BcdMccMnc as it's encoded as 24.008.
But SGSN code is using it as it would be byte by byte
sorted.

An MSC might decide to repeatedly retry Paging if it failed the first time, but
osmo-msc currently has no such mechanism. Instead, it so far had a bug that
retriggered a failed Paging from a start in a situation where there are SMS
pending for only one subscriber, and sending the SMS fails. osmo-msc patch
I24bf9f1c1167efe1080ae4cf47ed2ef0bd981e49 changes this behavior to accept a
Paging failure and not launch the same SMS again numerous times.
Adjust the tests to this new behavior.

If an MT SMS is triggered and not handled in the test, it is so far left behind
when the test ends. That causes Paging to retrigger for that SMS at any later
point during subsequent test runs, causing stray bogus test failures.
Actually remove the SMS from the SMS database and the queue with a new VTY
command: The vty command to clear failed SMS from the db is added in osmo-msc

Currently we do not simulate a situation where the HLR is unreachable to
the MSC. Lets add a test wehere the HLR is disconnected and an LU via
SGsAP is tried. The SGs interface should then carry out a reset
procedure.

The GSUP link between testsuit and osmo-msc is currently on by default
and can not be disabled. However, there may be situations where a
missing GSUP connection must be simulated. Lets add add a parameter to
disable GSUP if necessary.

The Template tr_SGsAP_RESET_IND is invalid since it requires vlr and mme
name at once, which is not a valid constellation in the real world. Lets
have two separate templates, one for MME and VLR, just like we have it
already with the ts_ versions of the templates.

When a subscriber is detached from non eps services, it gets fully
detached from 2G, which means that the VLR is supposed to remove the
subscriber. Lets check if the subscriber is in deed no longer known by
the VLR.

active subscribers from the VLR. Lets add a function, so that we can
check from TTCN3 if a specified subscriber is known by the VLR or not.

In the most use cases of f_SS_expect() we are not interested in
GSUP_PDU returned by this function. Calling it without storing
the returned value causes TTCN-3 compiler to complain:
warning: The value returned by function
`@HLR_Tests.f_SS_expect' is not used
Let's make use of previously unused variable 'res', and save
the returned GSUP_PDU to make the TTCN-3 compiler happy.

The PCU is supposed to forward any RR SUSPEND received by the BTS
on dedicated channels and pass it to the SGSN via BSSGP. This provides
knowledge to the SGSN that the MS is not reachable via PS/TBF anymore
until it completes its CC dedicated mode transaction and RESUMEs.
