[Mesa-dev] [PATCH 1/3] i965: Move GL_APPLE_object_purgeable functionality into a new file.

GL_APPLE_object_purgeable creates a mechanism for marking OpenGL objects
as "purgeable" so they can be thrown away when system resources become
scarce. It specifically applies to buffer objects, textures, and
renderbuffers.
The intel_buffer_objects.c file provides core functionality for GL
buffer objects, such as MapBufferRange and CopyBufferSubData. Having
texture and renderbuffer functionality in that file is a bit strange.
The 2010 copyright on the new file is because Chris Wilson first added
this code in January 2010 (commit 755915fa).
