We might want to split the interface changes as Patch 1/X, resolving
the issue Eric mentioned.

Note that unlike Robustness (seemingly where this patch is inspired
from) no_error has no hardware requirements.
Hence it will be better to
 a) add the extension in common/dri_util.c
 b) add it to all the DRI drivers, including classic nouveau, i915,
radeons, r200, swrast and gallium swrast (st/dri/drisw.c)

Thanks
