Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/5432

to look at the new patch set (#3).

ctrl_test: expand to test message handling and detect mem leaks

Subsequent patches that tighten CTRL input validation will make the results
more interesting.
