        new-run-webkit-tests: change TestResults to be serializable

        In preparation for changing new-run-webkit-tests from
        multithreaded to multiprocess, we need to make sure the data
        going between the threads is easily serialized over a socket.

        This change adds serialization/pickling for the TestResults and
        TestFailure objects (using cPickle).

        The TestFailure objects included a "has_wdiff" flag for Text
        results, but the flag wasn't being used, so I've removed it,
        simplifying the state to basically a set of enum objects with
        associated methods.
