Import experimental NS2 support and accumulated GPU fixes

Bring the NS2 patch and local follow-up fixes onto Eglantine master.
Includes native graphics services, instruction translation, syncpoint
cancellation acknowledgement, texture handling and diagnostics.

Experimental checkpoint; not ready to merge. The original Eden build
passed, but this rebased branch has not been built or tested.
