[Mesa-dev] [PATCH 00/38] Constify __DRI*Extension usage and misc cleanup

[Emil Velikov]

Rather trivial yet long series, that handles 

 - improve the readability of when instantiating an extension.
I.e. explicitly set each extension parameter.

 - use the typecasted name defined in the dri_interface.h
eg. __DRIblaExtension over struct _DRIblaExtensionRec

 - set the implemented version of the extension rather than the
one defined in dri_interface.h

 - and finally constify all possible use cases.

Build tested only.

I've kept the series separate for ease of review but can squash
before commit if people prefer.

 
With that done I can get back and respin Dave's gallium patches
for GLX_MESA_query_renderer, without stabbing my eyes out :P

Cheers
Emil
