            Assertion failure when opening a WebSocket connection
    
            I couldn't make a reliable test for this. Once the test from bug 32299 is landed, it
            will provide partial coverage, as I was frequently seeing the assertion failure with it.
    
            * platform/network/SocketStreamHandleBase.cpp: (WebCore::SocketStreamHandleBase::send):
            It's not an error if zero if returned from platformSend() - it just means that nothing could
            be pushed down to the network layer, and all data was queued for later.
            * platform/network/cf/SocketStreamHandleCFNet.cpp:
            (WebCore::SocketStreamHandle::readStreamCallback): This will no longer happen with SocketStream,
            but a client can potentially destroy the handle from any callback, so we need to check that
            this didn't happen.
            (WebCore::SocketStreamHandle::writeStreamCallback): Ditto.

         Roll out 51919 and 51920. They were incorrect and unnecessary right now.
