Rearrange the isisd northbound callbacks as following: * isis_nb.h: prototypes of all northbound callbacks. * isis_nb.c: definition of all northbound callbacks and their associated YANG data paths. * isis_nb_config.c: implementation of YANG configuration nodes. * isis_nb_state.c: implementation of YANG state nodes. * isis_nb_notifications.c: implementation of YANG notifications. This should help to keep to code more organized and easier to maintain. No behavior changes intended. Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
