Peter Maydell 15002921e8 Enable PV backends with Xen/KVM emulation
This is phase 2, following on from the basic platform support which was
 already merged.
 
  • Add a simple single-tenant internal XenStore implementation
  • Indirect Xen gnttab/evtchn/foreignmem/xenstore through operations table
  • Provide emulated back ends for Xen operations
  • Header cleanups to allow PV back ends to build without Xen itself
  • Enable PV back ends in emulated mode
  • Documentation update
 
 Tested-by: Paul Durrant <paul@xen.org>
 ... on real Xen (master branch, 4.18) with a Debian guest.
