[Mesa-dev] [PATCH 00/43] Constify __DRI*Extension usage and misc cleanup v2

[Emil Velikov]

A few changes since v1

 - New patches
03/43- Added yet another version note within dri_interface.h
05/43 - dumps the __DRItexBufferExtension's version to 3 and adds a stub
to prevent compilation problems. 
38-43 - glx/*: explicit assignment of struct members

 - Changes
06/43 - All drivers provide version 3 of __DRItexBufferExtension
30/43 - s/DRM_PRIME/DRI_PRIME
35,36/43 - s/threaded/treated/

 - Dropped const T *u = (const *T)a casts


While some patches may seems like bikeshedding, the constification is
quite nice. Let me know how you feel on topic.

Cheers
-Emil
