xen: features and fixes for 4.3-rc0

- - Convert xen-blkfront to the multiqueue API
- - [arm] Support binding event channels to different VCPUs.
- - [x86] Support > 512 GiB in a PV guests (off by default as such a
  guest cannot be migrated with the current toolstack).
- - [x86] PMU support for PV dom0 (limited support for using perf with
  Xen and other guests).

Thanks.

David
