In studying dri2proto.txt I noticed that it has several places that don't
mention the events that have been added.
I also noticed a couple of typos and a reference to a 'group' field
that does not exist.
Here are patches for those issues. I am unsure of the padding in the
DRI2_InvalidateBuffers event.
