        bindings for inline event handlers.

        * bindings/js/JSDOMApplicationCacheCustom.cpp:
        (WebCore::JSDOMApplicationCache::addEventListener):
        (WebCore::JSDOMApplicationCache::removeEventListener):
        * bindings/js/JSEventTargetNodeCustom.cpp:
        (WebCore::JSEventTargetNode::addEventListener):
        (WebCore::JSEventTargetNode::removeEventListener):
        * bindings/js/JSMessagePortCustom.cpp:
        (WebCore::JSMessagePort::removeEventListener):
