There are only trivial changes where the cap was renamed. It's ready as 
far as I'm concerned -- I've pushed the latest version to 
https://cgit.freedesktop.org/~nh/mesa/log/?h=arb_transform_feedback_overflow_query 
right now.

There's the issue of the firmware bug, but the series has a workaround, 
and if/when the bug gets fixed we can make the workaround conditional on 
the firmware version in a separate patch.

Cheers,
Nicolai
