vhost-vsock: add virtio sockets device
Implement the new virtio sockets device for host<->guest communication using the Sockets API. Most of the work is done in a vhost kernel driver so that virtio-vsock can hook into the AF_VSOCK address family. The QEMU vhost-vsock device handles configuration and live migration while the rx/tx happens in the vhost_vsock.ko Linux kernel driver. The vsock device must be given a CID (host-wide unique address): # qemu -device vhost-vsock-pci,id=vhost-vsock-pci0,guest-cid=3 ...
