Since the calling hook for old fpm is done in `rib_uninstall_kernel()`
inside, this calling place outside should be redundant. Just remove it.

When a peer has not established connection yet, these values:
`hostLocal`, `portLocal`, `hostForeign`, `portForeign` might
not have any values and json output will not display anything
for them. Modify the code to display some nominal values in
this situation so that parsers are not surprised.

It's possible for ospf6 to decide to delete a route after it's
removed all of the route's nexthops. It's ok to delete a prefix
alone - be a little more forgiving when preparing a route delete.

RFC9234 is a way to establish correct connection roles (Customer/
Provider, Peer or with RS) between bgp speakers. This patch:
- Add a new configuration/terminal option to set the appropriate local
role;
- Add a mechanism for checking used roles, implemented by exchanging
the corresponding capabilities in OPEN messages;
- Add strict mode to force other party to use this feature;
- Add basic support for a new transitive optional bgp attribute - OTC
(Only to Customer);
- Add logic for default setting OTC attribute and filtering routes with
this attribute by the edge speakers, if the appropriate conditions are
met;
- Add two test stands to check role negotiation and route filtering
during role usage.

- The parent of the daemonizing fork reports memleaks for the early
northbound allocations (libyang). If these were real memleaks these
would show up in the child as well; however, ignoring all memleaks in
the parent of the fork is too hard a sale. Instead, spend some CPU
cycles cleaning up the allocations in the parent after the fork and
immeidatley prior to exiting the parent after the daemonizing fork.

Allow end operator to set how long a nexthop-group is kept around
in the system after it is no-longer being used.
Signed-off-by: Donald Sharp <sharpd@nvidia.com>
Before deleting nexthop groups, that are installed,
from the system, start a timer and hold the nexthop
group for that time.
Suppose you have this scenario
a) create a static route with 1 x ecmp
creates a nhg with 1 x ecmp
b) create a static route with 2 x ecmp
creates a nhg with 2 x ecmp
deletes a's nhg
c) create a static route with 3 x ecmp
creates a nhg with 3 x ecmp
deletes b's nhg
d) create a different route with 1 x ecmp
creates another 1 x ecmp ( since a's ecmp was deleted )
e) create a different route with 2 x ecmp
creates another 2 x ecmp ( since b's ecmp was deleted )
If you don't delete the nhg, start a timer, the nhg's used
in steps a and b can be reused for steps d and e. This reduces
overhead work with zebra <-> kernel interactions and improves
the speed of the system.
So modify the code to note that an installed nexthop group should
be kept around a bit and hopefully reused.

Currently the code is marking the nhg as uninstalled but not
causing that to flood up to the dependent nhgs:
nhg 3 is a group of 1/2
1 -> interface A
2 -> interface B
Suppose A goes down, old code would mark nhg 1 as !VALID and !INSTALLED.
Suppose B then goes down, old code would mark nhg 2 as !VALID and !INSTALLED
But would not mark nhg 3 as !VALID and !INSTALLED (sort of assuming that
it would just be cleaned up by NHG refcounts ). I would prefer that
the code is pedantic about nhg 3 actually being removed from the system.
This code moves the setting of !INSTALLED into zebra_nhg.c where it
really belongs.

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.
