[Mesa-dev] Add extension EXT_sRGB_write_control

[Gert Wollny]

Dear all, 

I'd like to push this series [1] to enable the extension 
EXT_sRGB_write control  by the end of this week if there are no
objections. 

I ran it trough the intel-ci [2] with only some unrelated unstable
tests. 

many thanks for any reviews, 
Gert
