32b67a0aeb lib/printf: add %Ld/%Lu for int64_t/uint64_t
[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

17136bf23e lib, bgpd: Create iana_afi.h for storing iana_afi/safi enums
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.

9ee2f5741d tools: On shutdown no need to flush from tools/frr.in script
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.

63e653a21f lib: crash when FRR hostname length > 80 chars
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.

e241544469 bgpd: Filtering received EVPN routes based on VNI does not work
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.

f3f4562612 lib, zebra: Ensure route encoding has enough space
When you have compiled FRR with a large multipath number
then encoding large ecmp routes between zebra and the
routing daemons.  There exists a theoritical size
of multipath that will cause the encoding to be larger
than the ZEBRA_MAX_PACKET_SIZ.  In the cases where
we have allocated streams that will encode routes
then let's ensure that whatever size we have will
auto-fit what we say we can send.
