rip(ng)d_instance_disable unlinks the vrf from the instance which means
that rip(ng)_interfaces_clean never works, because rip(ng)->vrf is
always NULL there. This leads to the crash #6477.
Clean interfaces before disabling the instance to fix the issue.

DEFPY_YANG will allow the CLI to identify which commands are
YANG-modeled or not before executing them. This is going to be
useful for the upcoming configuration back-off timer work that
needs to commit pending configuration changes before executing a
command that isn't YANG-modeled.

Remove mid-string line breaks, cf. workflow doc:
.. [#tool_style_conflicts] For example, lines over 80 characters are allowed
for text strings to make it possible to search the code for them: please

When fetching the next route node in the RIB, skip the empty ones
to avoid calling other northbound callbacks later unnecessarily.

These are easy to get subtly wrong, and doing so can cause
nondeterministic failures when racing in parallel builds.

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.

Replace sprintf with snprintf where straightforward to do so.
- sprintf's into local scope buffers of known size are replaced with the
equivalent snprintf call
- snprintf's into local scope buffers of known size that use the buffer
size expression now use sizeof(buffer)
- sprintf(buf + strlen(buf), ...) replaced with snprintf() into temp
buffer followed by strlcat

Replace all `random()` calls with a function called `frr_weak_random()`
and make it clear that it is only supposed to be used for weak random
applications.
Use the annotation described by the Coverity Scan documentation to
ignore `random()` call warnings.

And again for the name. Why on earth would we centralize this, just so
people can forget to update it?
Signed-off-by: David Lamparter <equinox@diac24.net>
Same as before, instead of shoving this into a big central list we can
just put the parent node in cmd_node.
Signed-off-by: David Lamparter <equinox@diac24.net>
There is really no reason to not put this in the cmd_node.
And while we're add it, rename from pointless ".func" to ".config_write".

The only nodes that have this as 0 don't have a "->func" anyway, so the
entire thing is really just pointless.

ripd was using zclient_redistribute for installation but not
for removal. As such the lib/zclient.c was not properly tracking
add/removal. I think it would be best to just let rip to track
this instead of zclient.
Fixes: #5599

Rearrange the ripd northbound callbacks as following:
* rip_nb.h: prototypes of all northbound callbacks.
* rip_nb.c: definition of all northbound callbacks and their
associated YANG data paths.
* rip_nb_config.c: implementation of YANG configuration nodes.
* rip_nb_state.c: implementation of YANG state nodes.
* rip_nb_rpcs.c: implementation of YANG RPCs.
* rip_nb_notifications.c: implementation of YANG notifications.
This should help to keep to code more organized and easier to
maintain.
No behavior changes intended.
