        Moved storage for window event listeners into the window object.

        * bindings/js/JSDOMWindowCustom.cpp:
        (WebCore::JSDOMWindow::addEventListener):
        (WebCore::JSDOMWindow::removeEventListener): Add / remove window event
        listeners to / from the window object.

        * dom/Document.cpp:
        (WebCore::Document::removeAllEventListeners):
        (WebCore::Document::clear):
        (WebCore::Document::setWindowInlineEventListenerForTypeAndAttribute): Moved
        a bunch of code to the DOMWindow class, and left behind a few calls through
        to DOMWindow, to support legacy clients. (Eventually, these will go away, too.)

        * dom/Document.h: ditto.

        * dom/Node.cpp:
        (WebCore::Node::dispatchGenericEvent):
        (WebCore::Node::dispatchWindowEvent): Dipatch window events on the window
        object, not the document.

        * dom/Node.h:
        * dom/RegisteredEventListener.h: Moved RegisteredEventListenerVector
        declaration, since it's required in more places now.

        * history/CachedFrame.cpp:
        (WebCore::CachedFrame::clear): Updated for rename. Also, remove event
        listeners before detaching and clearing the document's window pointer,
        since the the document needs its window pointer in order to tell the window
        to clear its event listeners.

        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::stopLoading):
        (WebCore::FrameLoader::canCachePageContainingThisFrame):
        (WebCore::FrameLoader::logCanCacheFrameDecision): Updated for rename, and
        movement of window event listeners into the window.

        * loader/ImageDocument.cpp:
        (WebCore::ImageDocument::createDocumentStructure): Updated for movement
        of window event listeners into the window.

        * page/DOMWindow.cpp:
        (WebCore::DOMWindow::handleEvent):
        (WebCore::DOMWindow::addEventListener):
        (WebCore::DOMWindow::removeEventListener):
        (WebCore::DOMWindow::removeAllEventListeners):
        (WebCore::DOMWindow::hasEventListener):
        (WebCore::DOMWindow::setInlineEventListenerForType):
        (WebCore::DOMWindow::removeInlineEventListenerForType):
        (WebCore::DOMWindow::inlineEventListenerForType):
        (WebCore::DOMWindow::addPendingFrameUnloadEventCount):
        (WebCore::DOMWindow::removePendingFrameUnloadEventCount):
        (WebCore::DOMWindow::addPendingFrameBeforeUnloadEventCount):
        (WebCore::DOMWindow::removePendingFrameBeforeUnloadEventCount):
        * page/DOMWindow.h: Moved a bunch of code to the DOMWindow class, from the Document.

        * page/Frame.cpp:
        (WebCore::Frame::shouldClose): Updated for movement of window event listeners into the window.
