vnc: remove vnc_display global
Replace with a vnc_displays list, so we can have multiple vnc server instances. Add vnc_server_find function to lookup a display by id. With no id supplied return the first vnc server, for backward compatibility reasons. It is not possible (yet) to actually create multiple vnc server instances.
