Hi,
  This set of patches adds the core of the virtio-fs support to qemu;
it's marked experimental since the kernel patch isn't in yet; but
it's nearly there;  the spec has passed the voting stage, and
the kernel changes are queued in fuse-next.

  A future set of patches will add the optional DAX mapping support.

  The actual qemu change is pretty minimal, since it's really only
a virtio device with some queues.

v3
  Split the kernel header update out
    The contents correspond to the fuse-next world+a patch Stefan just
    sent to make that use the newer 'num_request_queues' name

  Update copyright year,
  Remove the assert in vuf_handle_output
    the virtio core code sometimes calls it during cleanup if the
    daemon dies first
  (I've not changed the comment about guest_notifier_mask/virtio-pci
   since that's copied in a bunch of virtio code going back ~5 years)
