Factored checkstyle config into it's own mvn project
This allows correct handling of multimodule checkstyle as
documented here:
http://maven.apache.org/plugins/maven-checkstyle-plugin/examples/multi-module-config.html
This involved:
- Adding a commons/checkstyle module to hold the space_and_tabs_checks.xml
- Altering commons/opendaylight to use commons/checkstyle
- Altering commons/concepts to use commons/checkstyle
- Altering commons/integrationtest to use commons/checkstyle
- Altering opendaylight/distribution to make sure to build commons/opendaylight
and commons/checkstyle
- Altering opendaylight/distribution to exclude commons/checkstyle from the
distribution zip file.
