Add multiple-device support virtio-loopback-adapter

Updates [v1]:
- The adapter supports multiple vhost-user devices running in
  parallel.
- Redesign the devices interfaces. Unified their common functionality
  and add it into vhost-user-loopback lib. This eases the addition of
  new vhost-user devices and makes the virtio-loopback adapter more
  device agnostic.
