xen: features and fixes for 3.18-rc0

- - Add pvscsi frontend and backend drivers.
- - Remove x86 _PAGE_IOMAP PTE flag, freeing it for alternate uses.
- - Try and keep memory contiguous during PV memory setup (reduces
  SWIOTLB usage).
- - Allow front/back drivers to use threaded irqs.
- - Support large initrds in PV guests.
- - Fix PVH guests in preparation for Xen 4.5.

Thanks.

David
