[PATCH v2 0/4] vhost-user-gpu get_edid feature

[Erico Nunes]

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.
