In order for Xen to be able to boot on systems with multiple PCI segments
(also called domains), a number of changes are necessary to the
hypervisor, the hypercall interface, the tools, and the Dom0 kernel, as
in most code paths and definitions there were not even provisions for
passing a segment number.

1: introduce notion of PCI segments
2: add new physdevop-s
3: adjust domctl interface
4: VT-d specific adjustments
5: AMD-IOMMU specific adjustments
6: Pass-through adjustments
7: config space accessor adjustments
