This adds support to the virtio-gpu get_edid command in qemu as the frontend as well as the vhost-user-gpu implementation in contrib/. So far, qemu has been outputting the following message: EDID requested but the backend doesn't support it. when using that implementation.
This is tested with vhost-user-gpu, the dbus ui backend and the monitor-edid application, which now shows complete "QEMU Monitor" edid data. The VHOST_USER_GPU_PROTOCOL_F_EDID protocol feature is required if the frontend sets the VIRTIO_GPU_F_EDID virtio-gpu feature. If the frontend sets the virtio-gpu feature but does not support the protocol feature, the backend will abort with an error.
