Stefan Sperling c307e689b4 introduce a TTCN3 test suite for SCCP 
This test suite acts as an SCCP server on top of M3UA.

SCCP tests are run against the sccp_demo_user program which
can be found in libosmo-sccp/examples. This program must be
started in client mode: sccp_demo_user -c
The SCCP test suite should then work out of the box with
the provided SCCP_Tests.cfg file and this additional change
to sccp_demo_user default point codes:
https://gerrit.osmocom.org/#/c/libosmo-sccp/+/9652/

There is currently only one test, for the libosmo-sccp crash
reported as issue OS#2666. The implementation of this test
is currently using an ugly workaround due to shortcomings of
the M3UA Emulation layer (see source code comments). Whether
a better solution is feasible is still to be determined.

The test requires a patch to the SCCP Protocol Emulation which
has been submitted upstream: https://git.eclipse.org/r/#/c/124552/
