Initial commit: 23b2a7ef52
changed the json output of `show bgp <afi> <safi> json` to
not have pretty print because when under a situation where
there are a bunch of routes with a large scale ecmp show
output was taking forever and this commit cut 2 minutes out
of vtysh run time.
Subusequent commit: f4ec52f7cc
changed this back.
When upgrading to latest version the long run time was noticed
due to testing. Let's add back this functionality such that
FRR can have reduced run times with vtysh when it's really
needed.

While this wasn't a problematic use of a format string, make it a

Passing a pre-formatted buffer in these places needs a `"%s"` in front

When running the build in a separate build directory, redirecting output
into a file can error out if the directory does not exist yet. Some
places already had `mkdir -p` calls, but not all.
Make all occurences of this consistently use `@$(MKDIR_P)`.

Daemons like staticd already implement nexthop zapi (un)registration.
b7ca809d1c ("lib: BFD automatic source selection") has implemented a
concurrent nexthop (un)registration. Some nexthop could be unregistred
by the bfd whereas they were still needed by the daemon.
Let the deamons deal with nexthop zapi (un)registration.

b7ca809d1c ("lib: BFD automatic source selection") has added a dedicated
zclient socket for nht tracking. Since the bfd lib is used by daemons
that already has a zclient socket, those daemons has now a second
zclient socket. However, zebra does not distinguish the two zclient
sessions. For example, the interfaces are asked a second via
zebra_message_send(zclient, ZEBRA_INTERFACE_ADD, VRF_DEFAULT) in
zclient_start(). As a result, callbacks functions like bgp_ifp_create()
are called a second time, which causes some processing overhead and
might cause bugs.
Re-use the existing zclient socket for nht tracking.
Note that BFD automatic source selection is only currently implemented
in staticd. Other daemons will require to add the following in their
ZEBRA_NEXTHOP_UPDATE callback function:
> if (zclient->bfd_integration)
> bfd_nht_update(&matched, &nhr);

Don't directly use `time()` for generating sequence numbers for two
reasons:
1. `time()` can go backwards (due to NTP or time adjustments)
2. Coverity Scan warns every time we truncate a `time_t` variable for
good reason (verify that we are Y2K38 ready).

Changes:
- Convert `unsigned int` to `time_t` to satisfy time truncation warnings
even though at this point we had already used the modulus operator.
- Avoid trying to access outside the bounds of the array
`months` array has a size of 13 elements, but the code inside the loop
uses `i + 1` to peek on the next month.

When setting rule for access-list ( and prefix-list ) without sequence, it
will automatically get a sequence by `acl_get_seq()`, and return
`CMD_SUCCESS` for command even this sequence value is wrong.
In this scene, `CMD_WARNING_CONFIG_FAILED` should be returned with a
warning.
So, add the check in `acl_get_seq()` and move `nb_cli_enqueue_change()`
after the check of wrong sequence.
Both `plist_remove_if_empty()` and `acl_remove_if_empty()` should ignore
this check, there is no change on them.

The list delete function on creation was set to srv6_locator_chunk_free
Which takes a double pointer and dereferences it to free the data.
When list_delete is called it calls the delete function like this:
if (*list->del)
(*list->del)(node->data);
The data is not passed in by reference and as such we do not have
a double pointer. Fortunately this list_delete is only really
called on shutdown when the locator was deleted and we do not
have a fun situation where we were suddenly freeing 'something'.
