Okay, following your advice I'll get rid of the explicit alignment/size
stuff from domctl/sysctl. But it *would* still be nice to have the script
that prints field offsets/sizes -- for the originally stated purpose of
ensuring that we don't accidentally break ABI compatibility. If it isn't too
much hassle, it would be great if you could bend your scripts to that
purpose.

 Thanks,
 Keir
