See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
The test seems to fail when executed outside of a debugger. A delay
between creating the connections and checking the connection count appears
to fix the problem.
Refactored the test to use stack allocated objects and favored assertion
style functions over conditional clauses with failing assertions inside
them.
