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.

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.

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

At the moment the SGs interface is started and connected in all tests in

The idea of this test case is to verify SM-RP-MR assignment for
a few concurrent MO/MT SMS being sent over GSUP.
Basically, the algorythm is the following:
1.0 establish a RAN connection,
1.1 send CM Service Request for MO SMMA indication,
1.2 submit MO SMMA indication on DTAP,
1.3 expect MO-ForwardSM-Req on GSUP,
2.0 send MT SMS using MT-ForwardSM-Req on GSUP,
2.1 expect CP-DATA/RP-DATA for MT SMS on DTAP,
3.0 compare both SM-RP-MR values (for MT, assigned by the MSC),
3.1 send MO-ForwardSM-Res for MO SMMA on GSUP,
3.1.1 expect CP-DATA/RP-ACK for MO SMMA on DTAP,
3.2 send CP-DATA/RP-ACK for MT SMS on DTAP,

The testcase TC_lu_and_mt_sms_paging_and_nothing is currently using an
IMSI that ends on 43. The same IMSI is used by TC_mo_cc_bssmap_clear as
well. Since TC_lu_and_mt_sms_paging_and_nothing is running before
TC_mo_cc_bssmap_clear, the re-use of the IMSI triggers the MSC to
continue the paging procedure. The MSC then eventually tries to deliver
the SMS from TC_lu_and_mt_sms_paging_and_nothing. This will disturb the
execution of TC_mo_cc_bssmap_clear, which then fails.
Lets make sure that TC_lu_and_mt_sms_paging_and_nothing uses an
individual IMSI that is never used again throught the execution of the
testsuite.

At the moment the sgsap always enabled in the testsuite. This means the
testsuite will try to connect the SGs interface of osmo-msc on
initalization. If the connection fails, the testcase will fail also.
Unfortunately the related patches that add the SGs interface to osmo-msc
are not yet merged to master. This causes almost all testcases to fail,
so lets have the SGs interface as an option that we can switch on when
the SGs interface patches are merged to master.
