We are going to implement backend-transfer feature: some devices

virtio-net will migrate its attached TAP netdev, with all its
connected file descriptors.
Let's add a command to list supporting devices (no one for now),
together with necessary infrastructure in qdev code.
Use case?
Will add:
With this command management tool can query such lists on source and
target, and get intersection of them, to now the set of devices, for
which we can enable backend-transfer for given source and target QEMUs.
