        Expose page dismissal event status through the WebKit API for chromium.
        https://bugs.webkit.org/show_bug.cgi?id=55844

        Chromium will find it useful to know the page dismissal status (i.e.,
        whether a frame is in the midst of executing a beforeunload or unload
        handler), so expose that information through the chromium port in the
        WebKit API.

        This is my second attempt at this patch. The previous one broke
        downstream Chromium builds of some unit tests which had classes derived
        from WebFrame (and thus became uninstantiable because of this new pure
        virtual method). Those have now been fixed (http://crrev.com/77101).
