reallocarray() is walled behind stupid feature macros on various
platforms and doesn't quite gain us much in that particular use case.

This makes printfrr extensions available in most of our format strings.
snprintf() is the obvious exception.

Simple documentation update for the new `clear ip mroute [vrf NAME] count`
command to the FRRouting documentation.

[u]int64_t is the only type in the intX_t family that needs
special-casing for printf since the calling convention may differ
between 32-bit and 64-bit systems.
Adding the L specifier allows us to eschew the gnarly-looking PRIu64.

The get_route_map_delete_event function should return a value
even if we never get to that part of the function. Make sure
we know why we are here so it can be fixed appropriately in
the future.

A couple of places of strncpy snuck in due to my confusion
about if Quentin's earlier change had gotten in. Just some
code in flux. This should fix the issue/warnings in our
CI system.
Recent commits rewrote the `clear mroute` command and this caused
these two two functions to no longer be used, remove.

the interface search done was not looking in the appropriate zns. The
display was then wrong. Update the show command with the correct zns.

The zebra_size_t type needs to be owned by zclient.h since
it is part of the zapi protocol. Move it to where the
structure belongs.

The header inclusion in mtracebis.c should include zebra.h
and not config.h. There are other issues that need to
be worked through as well, but we can do this in the future.

zebra.h had some defined flags that were being used
as part of the route encode/decode functionality. These
belong in the zclient.h code.

We have some functions that are owned by log.c, so
move their declarations from zebra.h to log.h

The iana_afi_t and iana_safi_t were being created in zebra.h
and zebra.h is a bit of a dumping ground. When the iana_afi2str and
iana_safi2str functions were created, it was correctly pointed out
that we should just use the internal afi_t and safi_t 2str functions
but to do that we would need to include prefix.h in zebra.h. Which
really is not the right thing to do. This tells us that we need
to break out this code into it's own header.
Move to iana_afi.h the enums and specific functions and remove
from zebra. Convert to using the afi2str and safi2str functions.

Modify the code such that we can auto turn the iana values of afi
and safi to pleasant to read strings.

Zebra already flushes routes on proper shutdown if you are not
using the -K option. If you are using the -K option then you
do not want the tools/frr script to flush routes.
If zebra crashes and we restart then load up will either delete
the routes or leave them depending on the -K option.

Although the RFC states hostname length should be < 255 chars,
FRR allows infinite length technically. However, when you try
to set a hostname > 80 chars, you would immediately notice a crash.
RCA: Crash due to buffer overflow. Large buffer sprintf'd into smaller
buffer. Usage of sprintf function instead of snprintf which is safer.

Issue1: When "neighbor X.X.X.X route-map RM-VNI-FILTER in" is configured under evpn address-family,
all the received routes are dropped regardless of whether the route has a matching vni or not.
Issue2: Routes with 2 labels are not filtered correctly
Issue3: Interpreting the label based on tunnel type, vxlan was not done correctly.
Vxlan label has 24 bits, whereas, MPLS label is 20 bits long
Fix1: The handler bgp_update() that services the received route ignored the route's label while deciding whether to filter it or not. As part of the fix, the handler now uses the label info to make the decision about whether to filter the route or not.
Fix2: route_match_vni() now tries to match both the labels within the route, not just the one.

Say, more than one sequence of a route-map uses the same named entity
in its match clause. After that entity is removed from any one of the
route-map sequences, any further changes made to that entity doesn't
dynamically take effect.
A reference counter, that allows the named entity to keep a count of
the route-maps dependent on it, has been introduced to address this issue.
