thunderbolt: Let the connection manager handle all notifications
Currently the control channel (ctl.c) handles the one supported notification (PLUG_EVENT) and sends back ACK accordingly. However, we are going to add support for the internal connection manager (ICM) that needs to handle a different notifications. So instead of dealing everything in the control channel, we change the callback to take an arbitrary thunderbolt packet and convert the native connection manager to handle the event itself. In addition we only push replies we know of to the response FIFO. Everything else is treated as notification (or request) and is expected to be dealt by the connection manager implementation.
