xen: features and fixes for 3.18-rc0

Browse source 
- Add pvscsi frontend and backend drivers.
 - Remove _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
