qemu patches, queued for qemu 4.0.0:

Previous libvirt discussion around this:
https://www.redhat.com/archives/libvir-list/2018-August/msg01073.html

Changes since v2:
* Some prep patches merged
* filesystem model dropped the -9p naming, now uses virtio-{non-}transitional
  like other devices
* Now uses a single capability QEMU_CAPS_VIRTIO_PCI_NON_TRANSITIONAL
  which is set whenever any of the -transitional or -non-transitional
  devices are present.
* Add a formatdomain section 'Virtio transitional devices' and reference
  it from each relevant device section
* if virtio-transitional specified, and qemu is too old but has the
  disable_X options, convert it to explicit
  disable-legacy=off,disable-modern=off
* Misc small changes pointed out in review

Thanks,
Cole
