Hanna Czenczek bca3e2a138 vhost-user-fs: Implement internal migration 
A virtio-fs device's VM state consists of:
- the virtio device (vring) state (VMSTATE_VIRTIO_DEVICE)
- the back-end's (virtiofsd's) internal state

We get/set the latter via the new vhost operations to transfer migratory
state.  It is its own dedicated subsection, so that for external
migration, it can be disabled.
