Change http://review.whamcloud.com/19789 doesn't switch Lustre over to
using xattr handlers. As long as Lustre doesn't use those (i.e., use
posix_acl_access_xattr_handler and posix_acl_default_xattr_handler),
it will still need the uid/gid namespace conversion code in ll_getxattr and
ll_setxattr for this patch to be correct.

The merge conflict between this patch and http://review.whamcloud.com/19789
is easily resolved though.
