7603eca36d lib: skip route-map optimization if !AF_INET(6)
Currently we unconditionally send a prefix through the optimized
route-map codepath if the v4 and v6 LPM tables have been allocated and
optimization has not been disabled.
However prefixes from address-families that are not IPv4/IPv6 unicast
always fail the optimized route-map index lookup, because they occur on
an LPM tree that is IPv4 or IPv6 specific.
e.g.
Even if you have an empty permit route-map clause, Type-3 EVPN routes
are always denied:
```
--config
route-map soo-foo permit 10

--logs
2023/02/17 19:38:42 BGP: [KZK58-6T4Y6] No best match sequence for pfx: [3]:[0]:[32]:[2.2.2.2] in route-map: soo-foo, result: no match
2023/02/17 19:38:42 BGP: [H5AW4-JFYQC] Route-map: soo-foo, prefix: [3]:[0]:[32]:[2.2.2.2], result: deny
```

There is some existing code that creates an AF_INET/AF_INET6 prefix
using the IP/prefix information from a Type-2/5 EVPN route, which
allowed only these two route-types to successfully attempt an LPM lookup
in the route-map optimization trees via the converted prefix.

This commit does 3 things:
1) Reverts to non-optimized route-map lookup for prefixes that are not
   AF_INET or AF_INET6.
2) Cleans up the route-map code so that the AF check is part of the
   index lookup + the EVPN RT-2/5 -> AF_INET/6 prefix conversion occurs
   outside the index lookup.
3) Adds "debug route-map detail" logs to indicate when we attempt to
   convert an AF_EVPN prefix into an AF_INET/6 prefix + when we fallback
   to a non-optimized lookup.

Additional functionality for optimized lookups of prefixes from other
address-families can be added prior to the index lookup, similar to how
the existing EVPN conversion works today.

New behavior:

97b1935748 lib: fix vtysh core when handling questionmark
When issue vtysh command with ?, the initial buf size for the
element is 16. Then it would loop through each element in the cmd
output vector. If the required size for printing out the next
element is larger than the current buf size, realloc the buf memory
by doubling the current buf size regardless of the actual size
that's needed. This would cause vtysh core when the doubled size
is not enough for the next element.

719b26901c lib: Link State memory corruption
In function ls_find_subnet(), prefix argument is directly copied into
subnet.key structure to find corresponding subnet in RB Tree. This could leadr
to a memory corruption. Function prefix_copy() must be used instead.

This patch replaces the direct prefix copy by a call to prefix_copy() function
to avoid this memory issue.

c7991cc54b ripd: Fix malformed route-map
Currently the process of the `route-map` configuration for `per-vrf-rip`
is wrong.

There are two problems:
1. `ctx->name` for `if_rmap_ctx`  is not initialized in `if_rmap_ctx_create()`.
2.  The global `if_rmap_ctx_list` is wrongly used for `per-vrf-rip`.

So, two changes for it:
1. Correctly initializes `ctx->name`.
2. Use specific `if_rmap_ctx` for `per-vrf-rip`, not global one.

Note, this related implementation for `route-map` is only for `ripd`.

Before:
```
anlan(config)# route rip vrf vrf1
anlan(config-router)# route-map aa in lan
anlan(config-router)# do show run
!
router rip
 route-map aa in lan
exit
!
```

After:
```
anlan(config)# route rip vrf vrf1
anlan(config-router)# route-map aa in lan
anlan(config-router)# do show run
!
router rip vrf vrf1
 route-map aa in lan
exit
!

tl;dr -> Effectively, in this test setup we have 300 dynamic bgp
sessions all of which are using bfd.  When a peer collision is detected
or we remove the peers, if an event has been scheduled but not actually
executed yet the event event was not actually being stopped, leaving
the bsp pointer on the thread->arg and causing a crash when it is
executed.

Before this patch, if we destroy `any` flag for a prefix-list entry, we always
set destination as 0.0.0.0/0 and/or ::/0.

This means that, if we switch from `ip prefix-list r1-2 seq 5 deny any` to
`ip prefix-list r1-2 seq 5 permit 10.10.10.10/32` we will have
`permit any` eventually, which broke ACLs.

a77ea81ef3 lib: do not reopen a zclient socket for bfd
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);

ff9232c83b lib: remove dead logic code
If we got inside the condition of `vrfp->status == VRF_ACTIVE` then
don't make the same check again.

0839d0c742 lib: fix gmtime_assafe potential issues
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.
