[Mesa-dev] Request to revert commit [3d81e11b49366b5636b8524ba0f8c7076e3fdf34] mesa: remove, unnecessary, 'sort by year' for the GL extensions

[Federico Dossena]

As most of you are probably aware of, id2 and id3 games store GL 
extensions in a buffer that's too small for modern systems. This usually 
leads to a crash when MESA_EXTENSION_MAX_YEAR is not set, but what the 
creator of this commit didn't know is that some id3 games (the more 
"recent" ones) don't crash, they just truncate the string. As a result 
of this commit, these games can't detect some extensions and therefore 
don't work properly.

I discovered this while trying to figure out why dynamic lights in Star 
Trek Voyager Elite Force (2000) suddenly broke with Mesa 18. I discussed 
this with Ronald Scheidegger, who's been very helpful and helped me 
figure out what was going on.

Personally, I see nothing wrong with reverting this commit and keeping 
the extensions sorted by year, it doesn't impact performance and it 
doesn't break anything modern. What do you think about it?
