Surface map and unmap needs a pipe_context for gallium,
and as such dri_context. I don't know what the best way to solve
that in gbm, either via a hidden dri_context[1] or via a
new gbm_context.

Cheers, Jakob.

[1] which I don't like since we can't get to it if with
fences since if we actually want to support better command
scheduling then what we currently have.
