Fixes: 2a1c520e9f ("isisd: split northbound callbacks into multiple files")

This path replaces isisd_format_id, sysid_print, snpa_print, rawlspid_print and
isonet_print functions by the new printfrr ISO System ID & Network Address
format facilities. It also updates the isisd code to the new iso_address
structure defined in lib/iso.h

Now that the "frr-interface" list has a "state" container, move the
IS-IS interface state nodes underneath it using a new augmentation.
Also, update the IS-IS SR topotest to account for this change. Make
use of symlinks where possible to avoid having multiple files with
the same content.

Add a null check to solve the problem (circuit->u.bc.adjdb[level - 1]
is guaranteed to be non-null only on L1/L2 areas).

Having a fixed set of parameters for each northbound callback isn't a
good idea since it makes it difficult to add new parameters whenever
that becomes necessary, as several hundreds or thousands of existing
callbacks need to be updated accordingly.
To remediate this issue, this commit changes the signature of all
northbound callbacks to have a single parameter: a pointer to a
'nb_cb_x_args' structure (where x is different for each type
of callback). These structures encapsulate all real parameters
(both input and output) the callbacks need to have access to. And
adding a new parameter to a given callback is as simple as adding
a new field to the corresponding 'nb_cb_x_args' structure, without
needing to update any instance of that callback in any daemon.
This commit includes a .cocci semantic patch that can be used to
update old code to the new format automatically.

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.
