Patch to add dmabuf export to gldownload

Turns out I was able to completely avoid looking for the video meta on the
input side, and get all of the parameters I needed from the video info instead.
 On the output side, if the allocation supports the video meta, I add it, and
if not, then I check the offsets/strides to see if they match the video info. 
If they don't, then I reject the export and we fall back to the previous case.

Here's a new patch that implements that, as well as all of the previous
suggestions.  Does that cover all of the things you brought up?
