spice: support streaming-video parameter
This adds a streaming-video=filter|all|off attribute. It is used to change the behavior of video stream detection in spice, the default is filter (the default for libvirt is not to specify it - the actual default is defined in libspice-server.so). Usage: <graphics type='spice' autoport='yes'> <streaming mode='off'/> </graphics> Tested with the above and with tests/qemuxml2argvtest. Signed-off-by: Alon Levy <alevy@redhat.com>
