Xpra: Ticket #510: video stream pass-through

Similar to #509 and related to #410: we could register a dummy libva video decoder and most video players/browsers would talk to it instead of the X11 server, we can then grab the raw h264 or vp8 stream from it, saving us the cost of decoding it on the server then re-encoding it ourselves!

Potential problems:

#56 will have to come first.

No progress on #56, re-scheduling.

Probably easier to just implement a wayland backend (#387) which will give us a surface for video.
