The problem is that when we run watchfrr.sh/frrinit.sh, we get something like:
```
cat: '"/var/run/frr/staticd.pid"': No such file or directory
cat: '"/var/run/frr/babeld.pid"': No such file or directory
cat: '"/var/run/frr/zebra.pid"': No such file or directory

When starting a daemon, print the full command run by the init script to
start it. This gives more information and is especially helpful when
debugging wrap commands.
Also add some more logs to vtysh_b to print the command used there,
log when we exit early because frr.conf doesn't exist, and simplify the
code path for creating the command to use.

The explanation block for watchfrr_options was split into two blocks,
one explaining the --netns option and one making a vague statement that
the init script provides the list of daemons to start. The former can be
merged with the latter and the latter is more useful when stated as a
caveat for what you should actually use watchfrr_options for.

We support 'wrap' variables in /etc/frr/daemons, but the explanation
given there doesn't touch on some of the subtleties of using these
variables.
The variables were designed for use with Valgrind, which has special
behavior when run with programs that daemonize; Valgrind will intercept
the fork()'d child process and run itself instead of the child. This
behavior allows it to follow the same forking semantics as the target
program.
For virtually every other wrapper, the wrap variables do not work as
demonstrated because the wrapper programs do not daemonize. If the
wrappers do not daemonize, they will block the init script. The examples
given with "perf" for example simply do not work, because perf remains
in the foreground even as it tracks forked children.
This patch adds an explanation of the behavior expected by the init
script and offers a solution for getting that behavior.

Fix daemon shutdown broken by f0cccaa6bf. Now
we still don't complain about missing PID files but actually stop the
running daemons.
The previous fix was broken because it passed a new "--all" option to
daemon_stop which wasn't handled properly (it assumed $1 contains the
daemon name when at that time it acutally contained the "--all" option).
Plus, "--all" wasn't actually necessary, because we already passed
"--reallyall" from all_stop to daemon_stop after the daemon name.
So remove "--all" again and simply check for "--reallyall" in $2. This
should *really* fix#11317.

Since 1686b1d486, we try to stop all daemons,
even those which are not (no longer) enabled in /etc/frr/daemons. But we
shouldn't complain about missing PID files for daemons which have never been
started and just silently ignore those.

When a bgp neighbor removed from associated to peer-group,
the neighbor is fully deleted, subsequent deletion of any
configuration related to the neighbor leads to failure
in frr-reload.
Fix: In frr-reload lines to delete check if any neighbor with
peer-group removal line is present, if so then remove any
further config deletion associated the neighbor needs to removed
from the lines to delete.

BGPd does not allow default instance deletion
in presence of bgp vrf instance;
frr-reload script fails if delete list contains
default instance followed by vrf instance.
Fix:
frr-reload scans lines_to_delete to look for
'router bgp' and 'router bgp vrf ...' line.
If both are present switch the order to delete
bgp vrf instance(s) than default instance at the end.

file is 0640 (root:adm) (unless logrotated) and that doesn't allow adm group

If a user enters:
/usr/lib/frr/frrinit.sh start
<modifies daemons file to remove a daemon from being used>
then calls:
/usr/lib/frr/frrinit.sh stop
The daemon(s) that are removed from the file are not stopped.
Apparently in shell scripting naming the variables the same
as the callee does not work as one would think. Just renaming
the variable to something else solved the problem.

Problem:
During restarting frr.service, it throws annoying warnings:
Cannot stop bgpd(and others): pid file not found.
Root Cause:
During restarting process, systemd uses "stop", and watchfrr
uses "restart".
Yes, watchfrr using "restart" is to avoid systemd failing to stop.
But it should be quiet.
Fix:
During restarting service, suppress these warnings from watchfrr.

checkpatch.pl has a hardcoded list of printf extensions supported... by
the Linux kernel. This happens to have covered the ones we have in FRR
so far, but `%pPA` isn't on the list and others may not be either.
Since we have the frr-format GCC plugin (and CI runs that on Debian 11)
we don't really need these checks in checkpatch.pl.
