Add vhost-user-input-pci
Add a new virtio-input device, which connects to a vhost-user backend. Instead of reading configuration directly from an input device / evdev (like virtio-input-host), it reads it over vhost-user protocol with {SET,GET}_CONFIG messages. The vhost-user-backend handles the queues & events setup.
