    v12a: Move interface structure union member to the end, while moving
         the whole public header block into a __XEN__ / __XEN_TOOLS__
         conditional block.
    v12: Restore changes as much as possible to my original version, fixing
         a few issues that got introduced after handing it over. Unionize
         new public memop interface structure to allow for non-PCI to be
         supported later on. Check flags to have all currently undefined
         flags clear. Refine adjustments to xen/pci.h.
