A few more exports than I was expecting (possibly suggesting some of
those should be common functions), but it looks like what I had in
mind. I'll take a closer look to see if we can use those exports to
define a saner interface.

After this, the next big job is splitting i915_vma into HW facing and
GEM facing.
