This series addresses some issues identified in the virtio-user driver
when configured in server mode.

Firstly, properly identify the backend type in this mode.

Secondly, ensure no get/set status commands are sent before protocol
feature negotiation to avoid sending them to a backend that does not support them

And finally, add get/set status as per virtio spec so that it can work with
modern vhost-user backends that rely on this message to start the device.

Added patch 2 and 3 addressing additional issues
Check errno to select vhost-user backend and log the detected backend

Adrian Moreno (3):
  virtio-user: fix backend selection if stat fails
  virtio_user: don't set/get_status until FEATURES_OK
  virtio-user: set status on virtio-user reconnect
