[PATCH 0/2] vhost-user-gpu get_edid feature

[Erico Nunes]

This adds support to the virtio-gpu get_edid command when using 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.

In this v1, I would appreciate some feedback especially regarding:
- Can we enable it by default or do need to create another config option
  flag for it?
- Can we now also remove the "EDID requested but the backend doesn't
  support it." warning and logic from hw/display or do we still want to
  keep that around for other potential implementations of
  vhost-user-gpu?
- The structs used as payloads of the vhost-user-gpu messages. Looks
  like there was no command so far requiring bidirectional messages with
  different payloads so I just based it on similar available ones.

Thanks
