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 stacktrace generation is now a part of the maxbase library. The code
is the same code that was previously defined in gateway.cc as a part of
MaxScale.
