[Mesa-dev] UBO support patches update

[vlj]

Hi,

I updated coding style thank to Bryan Paul comments.
Besides there are additional work on the API implementation
(although it is still uncomplete) ; the parser should now handles 
default UBO layout (even if currently layout is ignored, std140 is the
only layout implemented).

UBO information are propagated to tgsi opcode (using an ugly hack,
glsl/mesa_to_tgsi dont seem to be designed with multiple const buffer
in mind atm), but currently there is no corresponding buffer upload.

All patches but the last one can be reviewed, however there is still
work to be done to have full UBO support.

Regards,
Vincent
