mesa/swrast/st: add ARB_occlusion_query2 support.
This gets my vote for most pointless extension of all time, I'm guessing
some driver could possibly optimise for this instead of counting it might
just get a true/false, but I'm not really sure.
need this to eventually advertise 3.3 despite its total uselessness.
