In future version of the series that is deem ready, I think it would be
useful to have this change in libxl_types.idl and the change that remove
the macro call from the C file in the same patch. It would make it
possible to review discrepancies.

The change in the idl for vfb is different that the change in the C
file:

No add function ;-)

And libxl doesn't build anymore with the last patch applied. They are
maybe also issues with functions that are static and thus are not
accessible from other c files.
