node: Add port_info event

Browse source 
Add a port_info event. With this, we get updates to ports pushed to
us, which is more convenient and also allows for better dynamic
add/remove of ports.
We don't need to the PortChanged event anymore
We can remove the get_port_ids/get_n_ports/port_get_info methods.
