        Fix <rdar://problem/5952405>.  The unbeforeunload count cannot be cleared when it is dispatched because it is possible to be called again.  Clear it after the unload event is dispatched.

        Test: fast/events/onunload-clears-onbeforeunload.html

        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::stopLoading):
        * page/Frame.cpp:
        (WebCore::Frame::shouldClose):

        implement the beforeUnload UI delegate so that DRT will dispatch beforeunload events.

        * DumpRenderTree/mac/UIDelegate.mm:
        (-[UIDelegate webView:runBeforeUnloadConfirmPanelWithMessage:initiatedByFrame:]):
        * DumpRenderTree/win/UIDelegate.cpp:
        (SearchableWebViewHost::runBeforeUnloadConfirmPanelWithMessage):

        add test to test for beforeunload event handlers being removed after they have been fired.

        * fast/events/onunload-clears-onbeforeunload-expected.txt: Added.
        * fast/events/onunload-clears-onbeforeunload.html: Added.
