Fix transferring the zone from a master and the matching of notifies to source and dst IP addresses. Add `upstream` keyword as well, because it is needed for the same reasons as in the *file* middlware. Add some dire warning about upstream in the readme of both middlewares. Out of band testing, hidden by net build tag was added. Integration testing still needs to be setup.
