Given that the interface has clearly bitrotten since it was first
introduced, I think it is reasonable to declare amnesty to fix it properly.

As the format is chosen at configure time, I think it is reasonable for
the Xen interface to just hand back blobs, and require the tools in dom0
to know how to interpret them.
