gpu: Add the ability to wait on upload completion.
Patch originally by Eric Penner <[email protected]>.
We currently have high latency if need to wait for uploads
in the renderer client. If we can do a shallow client side
wait it will be much better. This is effectively the
same as doing synchronous uploads, but exposes less driver
bug surface area then mixing uploads across threads.
