We need to be calling snprintfrr() instead of snprintf() in places that
wrap snprintf in some user-exposed way; otherwise the extensions won't
be available for those functions.

This is mostly to help static analysis; since we know from the command
string which args are optional and which aren't, we can add assert()
statements on them.

clippy can't process #ifdef or similar bits inside of an argument list
(e.g. within the braces of a DEFUN or DEFPY statement.) Improve error
reporting to catch these cases instead of generating broken C code.

We can use `$ac_precious_vars` to get at autoconf's conception of which
environment variables are relevant. This makes "HOST_..." setup more
consistent for cross-compilation setups.

* adds a `--with-clippy=...` option to use a prebuilt clippy binary
* limits the autoconf tests done for `--enable-clippy-only`

A router-id change that isn't explicitly configured (a change
from zebra, for example) should not replace a configured vpn
RD/RT.

Even when using the classic CLI mode (i.e. when --tcli is not
used), the northbound code still uses vty->candidate_config
to perform configuration changes. From the perspective of the
user, the running configuration is being edited directly, but
under the hood the northbound layer does a full configuration
transaction for each command. When the running configuration is
edited by a northbound client other than the CLI (e.g. kernel,
gRPC), vty->candidate_config might become outdated, and this can
lead to lots of weird problems. To fix this, always regenerate
vty->candidate_config before each configuration command when
using the classic CLI mode. When using the transactional CLI,
the user needs to update the candidate manually using the "update"
command, otherwise the "commit" command will fail with this error:
"% Candidate configuration needs to be updated before commit".
Fixes some problems reported by Don after moving an interface from
one VRF to another one while zebra is running.

This version of container_of() should work on C++, by ditching the

Update pbrd to properly handle nexthop tracking.
When we get a notification that a change happened on a nexthop,
re-install it if its still valid.
Before, we were running over all routes and re-queueing them if they
were PBR routes. This commit removes that and puts all the processing
in PBR instead.

When we copy a new nexthop to cache and track, set its
next and prev pointers to NULL. We don't want those since
this is to be treated as a single nexthop.Other nexthops that
aren't in a group could hash to this nexthop so it doesn't
make sense to keep those pointers in the cache.

Without this, we end up restarting watchfrr with the systemd watchdog
non-functional & tripped a bit later. Also, if watchfrr is in the
"control" cgroup, systemd 232 will kill it. (241 apparently doesn't.
Can't find anything about this in systemd's ChangeLog though.)

Problem reported with "clear bgp l2vpn evpn * soft" clearing the
wrong afi/safi (cleared ipv6 unicast instead). Determined that
the calling function used the argv_find_and_parse_afi/safi routines
to determine the correct afi/safi to pass on. Since l2vpn/evpn were
missing from the lookup, the command defaulted to ipv6 unicast. This
fix just adds that afi/safi to the lookup routine.
