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 warning that tells the user that the session command history has been
exceeded is now only logged once. This is to prevent the message from
being repeatedly logged when the default value is not large enough.
Also fixed the session_limits test to use distinct session commands. This
way the session command history compaction is not in effect and the test
again tests the correct thing.
