Subject: [PATCH 18/24] CHROMIUM: i965: remove read-only restriction of imported buffers

Previously, there was a patch that already did this but there was
collateral damage to the OES_EGL_image_external extension that turned it
off. This change remodels the original patches to keep
OES_EGL_image_external turned on.
