[Mesa-dev] [PATCH] i965: Rename batch->exec_objects to validation_list

[Chris Wilson]

Within i965, we have many different objects and confusingly when
submitting an execbuf we have lists of both our internal objects and a
list of the kernel's drm_i915_gem_exec_object with very similar names.
Rename the kernel's validation list to avoid the collison as it is only
used for interfacing with the kernel and so a peripheral use of
"object".
