Create vhost_cuse directory and move vhost-net-cdev.c into vhost_cuse.
vhost-cuse driver will be divided into two parts: cuse driver specific message
handling(in cuse directory) and common message handling(in virtio-net.c).
vhost ioctl message is pre-processed in cuse and then sent to virtio-net
if is not terminated.
virtio-net.c provides common message handling for both vhost-cuse and vhost-user.
