Boy, that's a long commit message, but most of the stuff seems to 
already be in master as individual bugfixes, making it a little 
difficult to zoom in on the changes that actually change something.

Presumably git understands it though, as it was able to produce the 
summary above.  I guess this is another case where the commit scripts 
could be improved, though maybe it would be cleaner to try and extract 
out the *actual* changes when doing this kind of merge - would rebasing 
the external branch against current mesa have made this less verbose?
