        REGRESSION: Flash clicks/interactivity not working properly

WebCore:
        * bridge/mac/FrameMac.mm:
        (WebCore::FrameMac::handleMouseMoveEvent):
        (WebCore::FrameMac::handleMouseReleaseEvent):
        Restore parts of event dispatching that were removed when fixing
        bug 7323 - just bypass those for subframes.

WebKitTools:
        Teach TestNetscapePlugin to log events passed to it. To enable, set eventLoggingEnabled to true:

        <embed name="plg" type="application/x-webkit-test-netscape" width=100 height=100></embed>
        <script>
            plg.eventLoggingEnabled = true;
            // use eventSender to simulate events...
        </script>

        * DumpRenderTree/TestNetscapePlugIn.subproj/PluginObject.c:
        (pluginGetProperty):
        (pluginSetProperty):
        (pluginAllocate):
        * DumpRenderTree/TestNetscapePlugIn.subproj/PluginObject.h:
        * DumpRenderTree/TestNetscapePlugIn.subproj/main.c:
        (NPP_HandleEvent):

LayoutTests:
        * plugins/mouse-events-expected.txt: Added.
        * plugins/mouse-events.html: Added.
