Hi all,

As per [1], I've just merged a series of patches that upgrades the oVirt engine to use the latest maven-checkstyle-plugin and checkstyle packages.

Please note that the newer checkstyle is a tad stricter than the old one we used to have (read: it contains several fixes for bugs where the old checkstyle was supposed to find issues but missed them).
I also took the opportunity and added a couple of new checks that enforce rules we were de-facto adhering to anyway.

If any problems come up, please let me know.
