QEMU 2.12 introduced a new type of display for mediated devices using vfio-pci backend which allows a mediated device to be used as a VGA compatible device as an alternative to an emulated video device. QEMU exposes this feature via a vfio device property 'display' with supported values 'on/off/auto' (libvirt will default to 'off').This patch adds the necessary bits to domain config handling in order to expose this feature. Since there's no convenient way for libvirt to come up with usable defaults for the display setting, simply because libvirt is not able to figure out which of the display implementations - dma-buf which requires OpenGL support vs vfio regions which doesn't need OpenGL (works with OpenGL enabled too) - the underlying mdev uses.
