vhost-user: add multi queue support
Based on patch by Nikolay Nikolaev: Vhost-user will implement the multi queue support in a similar way to what vhost already has - a separate thread for each queue. To enable the multi queue functionality - a new command line parameter "queues" is introduced for the vhost-user netdev.

Establish a vhost-user netdev, backed by a chardev @var{id}. The chardev should
be a unix domain socket backed one. The vhost-user uses a specifically defined
protocol to pass vhost ioctl replacement messages to an application on the other
end of the socket. On non-MSIX guests, the feature can be forced with
