D p tests

Run tests from d-p-tests. Old tests not removed, kept exactly in the same place. There is more to do, such as running generic tests from n-t-tests as well, and then eventually removing the old tests once this transport is in better shape.

Also, I don't know how to break connections in n-t-cci. This would first require adding a 'createTransportExposeInternals' function just like in n-t-tcp, to get access to the underlying endpoints, etc.
