This series adds support for a vgpu display to the qemu vfio code.

v6:
 - add support for hotplugging QemuConsoles.
 - drop vfio-pci-display device, re-add OnOffAuto display property.
 - add proper cleanup in finalize.

v5:
 - rebase to latest master
 - drop DeviceState->hotpluggable patch, use separate vfio-pci-display
   device instead so we can use DeviceClass->hotpluggable.
 - add vfio dma-buf patch.  Right now this can be tested with '-display
   egl-headless' only.  gtk and spice support is almost ready for merge
   and should follow soon.

cheers,
  Gerd
