Log Message:
Work in progress on PCI front-end/back-end support
front-end:
- add a xpci* at xenbus? which provides pci busses from the dom0
  xpci provides support routines for PCI config space operations and
  enumeration in xpci_xenbus.c
- hypervisor.c: do dom0-style PCI attach only ifdef DOM0OPS
- pci_intr_machdep.c:  check line value only if DOM0OPS

back-end:
- add a pciback* at pci? device which takes precedences over all
  other PCI devices (match return 500) and matches all devices passed
  to pciback.hide option on boot command line.
  It exports the PCI device informations to files in /kern/xen/pci/
- hypervisor.c: create /kern/xen earlier so pciback can create its
  entries while PCI devices are probed
- xen_machdep.c: add handling for pciback.hide=

frontend is know working on Xen 3.1.x dom0 with ahc(4) and pciide(4)
devices. uhci(4) fail when trying to allocate a large contigous DMA
buffer.

backend is work in progress; support in xentools is not there yet.
