        Test: fast/forms/input-text-self-emptying-click.html

        * page/MouseEventWithHitTestResults.h: Removed url, target, m_url and m_target,
        replacing them with isOverLink and m_isOverLink. Replaced innerNode with targetNode,
        and added logic to handle the case where the target node is removed from the document
        but the element the target node was in is still inside the document.
        * page/MouseEventWithHitTestResults.cpp: Added.

        * WebCore.xcodeproj/project.pbxproj: Added MouseEventWithHitTestResults.cpp.
        * WebCore.vcproj/WebCore/WebCore.vcproj: Ditto.

        * kwq/RenderTreeAsText.cpp: (nodePosition): Added a call to shadowParentNode so we
        correctly dump positions within shadow trees. This was needed to give a good result
        from my new test for this bug.

        * dom/Document.cpp:
        (WebCore::Document::prepareMouseEvent): Update to pass fewer parameters to the
        constructor for MouseEventWithHitTestResults. Now takes isOverLink boolean, and no
        longer takes href and target parameters.

        * page/Frame.cpp:
        (WebCore::Frame::handleMousePressEventDoubleClick): Use new name targetNode, instead
        of old name innerNode.
        (WebCore::Frame::handleMousePressEventTripleClick): Ditto.
        (WebCore::Frame::handleMousePressEventSingleClick): Ditto. Also change code to check
        if over a link to use !isOverLink instead of url.isNull.
        (WebCore::Frame::handleMousePressEvent): Ditto. Also remove unused "url" local variable.
        (WebCore::Frame::handleMouseMoveEvent): Ditto.
        (WebCore::Frame::handleMouseReleaseEvent): Ditto.
        (WebCore::Frame::passWidgetMouseDownEventToWidget): Ditto.

        * bridge/mac/FrameMac.mm:
        (WebCore::FrameMac::handleMousePressEvent): Use new name targetNode, instead of old
        name innerNode.
        (WebCore::FrameMac::handleMouseMoveEvent): Ditto.
        (WebCore::FrameMac::passSubframeEventToSubframe): Ditto.
        (WebCore::FrameMac::sendContextMenuEvent): Ditto.

        * page/FrameView.cpp:

        (WebCore::FrameView::handleMouseDoubleClickEvent): Ditto.
        (WebCore::selectCursor): Ditto. Also change code to check if over a link to use
