Implement the move constructor for containers.
This changes all the containers that uses QtPrivate::RefCount (QMap already had one), and QVariant In Qt 4.8, it was pointless to have the move constructor because we did not have quick way to re-initialize a null container. (shared_null still needed to be refcounted) But now that we have RefCount, and that the shared_null do not have reference count, we can implement a fast move constructor that do not generate code to increment the reference count.
