Add new vhost-user netdev backend Add a new QEMU netdev backend that is intended to invoke vhost_net with the vhost-user backend. It uses an Unix socket chardev to establish a communication with the 'slave' (client and server mode supported). At runtime the netdev will handle OPEN/CLOSE events from the chardev. Upon disconnection it will set link_down accordingly and notify virtio-net; the virtio-net interface will go down.

vhost-net: save & restore vhost-user acked features The initial vhost-user connection sets the features to be negotiated with the driver. Renegotiation isn't possible without device reset. To handle reconnection of vhost-user backend, ensure the same set of features are provided, and reuse already acked features.
