            Bug ID: 749845
           Summary: Client have problem to find the teardown response.
    Classification: Platform
           Product: GStreamer
           Version: unspecified

gst-rtsp-server patch

During http tunneled rtsp, sometimes client miss a rtsp teardown response since
it have started to get a packet and just received the first part of it.

This can happen if write_bytes in gst_rtsp_watch_write_data returns
GST_RTSP_EINTR. Then the rest of that message ends up in backlog queue.
If we then receive a Teardown then backlog queue will be flushed and second
part 
off message will be lost.

Solution is not flush during teardown. This flush during teardown was
introduced to fix a deadlock that now is fixed in handle_request more generally
by set backlog size to unlimited.
