    Source/WebCore:
    
    This change implement ShadowRoot::cloneNode() which throws an exception.
    This also adds an overloaded version cloneNode() to ShadowRoot.idl
    which is enabled only for JavaScript instead of changing the
    signature of Node::cloneNode().
    
    Note that changing the existing signature can break GObject bindings
    compatibility.
