Problem reported that in many circumstances, RAs created in the
process of bringing up numbered IPv6 peers with extended-nexthop
capability enabled (for ipv4 over ipv6) were not stopped on the
interface when those peers were deleted. Found several circumstances
where this occurred and fix them in this patch.

when removing a whole address-family block from ldpd config
we were erroneously trying to also remove each of the interface
sub-sub-contexts that belonged to it; this would effectively
re-enable the AF we just removed. Work around this by ignoring
these sub-sub-contexts if we detect that we are already
removing the parent block.

An async route notification can indicate that installation
has failed, but the handling code wasn't dealing with that
possibility correctly.

Dealing with PRIu64 is unfortunately a bit hacky in the frr-format
plugin, as in, it works correctly with snprintfrr, but breaks on plain
snprintf. There's no good solution unfortunately :/.

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

Since this command is modeled using YANG, it's already displayed
as part of the call to nb_cli_show_dnode_cmds(). Calling the
'isis_circuit_config_write' hook was only making that command
to be displayed twice.
The aforementioned hook is still necessary for fabricd, which wasn't
converted to the new northbound model yet.
Fixes#6281.

Stop sleeping if synchronous label-manager zapi session
has trouble during init: retry using a timer instead. Move
initial label-block request to a point where the LM zapi
session is known to be running. Remove the use of the
daemon 'instance' - we're using the session_id to distinguish
the LM zapi session.

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.

The intention here is to keep the code more organized. These wrappers
should be used by the northbound clients only, and never directly
by any YANG backend code.

Issue:
Configuring default-originate when static default route is previously
advertised results in withdrawal of the route.
Fix :
Delete the adj-out entry for the previously advertised static
default route without sending explicit withdraw message.
