there is now 2.4.0-RC2 of commons, and doctrine/dbal 2.3.4 that allows commons <2.5.0-dev. doctrine orm depends on dbal only, so i think we can now merge this PR safely. people will have to accept to install RC level but with our bundles all being alpha that should not be an issue.

i just updated things again and fixed tests that broke because of changes in master.
