add video cube

Uses gstreamer for a simple decoder.  If decoder can give us dma-buf's
directly, we'll directly use that as a texture (zero copy), otherwise
memcpy into a buffer from gbm.  This should work with both hw and sw
decoders.

Probably room for improvement.  And the interface between gl and the
decoder is pretty simple so I suppose other decoders would be possible.
(But hopefully they could already be supported via gstreamer.)
