        Test: fast/css/counters/content-021.html

        * rendering/CounterNode.cpp:
        (showCounterTree):
        Made parameter const because it is supposed to be so.
        * rendering/RenderCounter.cpp:
        (WebCore::previousInPreOrder):
        (WebCore::previousSiblingOrParent):
        (WebCore::parentElement):
        (WebCore::areRenderersElementsSiblings):
        (WebCore::nextInPreOrder):
        Added these local helper functions to help navigate the DOM tree
        enriched with :before and :after pseudo elements.
        (WebCore::planCounter):
        Fixed bug that would create a repeat counter for second and
        subsequent renderers associated with the same DOM element.
        (WebCore::findPlaceForCounter):
        (WebCore::makeCounterNode):
        Changed to use the new tree navigation functions described above
        instead of the Renderer Tree navigation functions.
        (WebCore::RenderCounter::rendererSubtreeAttached):
        (WebCore::RenderCounter::rendererStyleChanged):
        Optimized to not bother about counters until the renderers are
        finally attached.
        (showRendererTree):
        (showNodeTree):
        Debug helper functions used to debug Counter bugs.
