Add explicit path to the root source directory and allow invocation from
other directories. Also included qc_sqlite sources but excluded the SQLite
sources. Explicitly define the configuration in the MaxScale sources as
the one that will be used.
Changed from N invocations of uncrustify to one invocation with all files
as the program arguments. This should give a slight speedup when
formatting all sources.
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.
