Jenkins integration of OsmoBSC TTCN-3 test suite

[Harald Welte]

Dear all,

the last couple of weeks I've been spending a lot of time creating an
OsmoBSC test suite.  A lot of this was infrastructure work, as e.g.
there was no RSL implementation available yet for TTCN-3.

The code can be found at
http://git.osmocom.org/osmo-ttcn3-hacks/tree/bsc
there's a README.txt file included with more details (and further test
ideas).

I've also found some time for the docker + jenkins integration, whose
results can now be seen at
http://git.osmocom.org/osmo-ttcn3-hacks/tree/bsc (click on 'expand all'
to see details).

During the writing of the test suite I discovered a quite large number
of bugs in OsmoBSC and some of its dependencies, see the list below.

I'll stop working on the test coverage for now and focus on other areas
of testing first (as well as fixing some of the now-known bugs).  Any
help is greatly appreciated.
