Dave Airlie just implemented some Xv support as below, although not fully
support all functions.

glamor: add initial Xv support
This does YV12 and I420 for now, not sure if we can do packed without
a GL extension.

I don't think glamor support xmvc now.
However port those xmvc code to glamor is doable.

-intel needs to explicitly enable Xv support in its glamor backend, which it
does not yet do. I'm not sure if glamor could expose the hardware motion
