Currently, in `zebra_srte_client_close_cleanup` we use the `RB_FOREACH`
macro to traverse the SR policies tree. We remove the SR policies within
the loop. Removing elements from the tree and freeing them is not safe
and causes a use-after-free crash whenever the
`zebra_srte_client_close_cleanup` is called to perform cleanup.
This commit replaces the `RB_FOREACH` macro with its variant
`RB_FOREACH_SAFE`. Unlike `RB_FOREACH`, `RB_FOREACH_SAFE` permits both
the removal of tree elements as well as freeing them from within the
loop safely.

OSPF_MAX_LSA_SIZE does not represent the actual maximum size of LSA packets which may be larger than 1500 bytes. If relaying a large OSPF packet to the OSPF API, we do not allocate a big enough buffer to send over the API. This patch increases the maximum size of OSPF packets transmitted over the API.

The `sid vpn per-vrf export` VTY command in bgpd has been extended to
support up to 1048575 SIDs.
This commit updates the documentation of the `sid vpn per-vrf export`

Previously BGP supported up to 255 SIDs.
The PR https://github.com/FRRouting/frr/pull/11981 extended the
transposition computation algorithm in BGP to support more SIDs (up to
1048575 SIDs).
However the BGP VTY command for allocating an SRv6 per-VRF SID
(`sid vpn per-vrf export`) is still limited to 255 SIDs.
This commit extends the SID index in `sid vpn per-vrf export` VTY
command to support up to 1048575 SIDs.

Given that two routers are connected each other and they have IPv6
addresses and they establish BGP peer with extended-nexthop capability
and one router tries to advertise locally-generated IPv4-VPN routes to
other router.
In this situation, bgpd on the router that tries to advertise IPv4-VPN
routes will be crashed with "invalid MP nexthop length (AFI IP6)".
This issue is happened because MP_REACH_NLRI path attribute is not
generated correctly when ipv4-vpn routes are advertised to IPv6 peer.
When IPv4 routes are leaked from VRF RIB, the nexthop of these routes
are also IPv4 address (0.0.0.0/0 or specific addresses). However,
bgp_packet_mpattr_start only covers the case of IPv6 nexthop (for IPv6
peer).
ipv4-unicast routes were not affected by this issue because the case of
IPv4 nexthop is covered in `else` block.

We already have a global knob for graceful-shutdown, but it's handy having
per neighbor knob as well.
Especially when a single neighbor needs to be restarted/shutdown gracefuly.
We can do this route-maps, but this is a faster/cleaner way doing the same
for an operator.

This commit addresses an issue that happens when using bgp
peering with a rr client, with a received prefix which is the
local ip address of the bgp session.
When using bgp ipv4 unicast session, the local prefix is
received by a peer, and finds out that the proposed prefix
and its next-hop are the same. To avoid a route loop locally,
no nexthop entry is referenced for that prefix, and the route
will not be selected.
When the received peer is a route reflector, the prefix has
to be selected, even if the route can not be installed locally.

If you have this order in your configuration file:
no fpm use-next-hop-groups
fpm address 127.0.0.1
the dplane code was using the same event thread t_event and the second
add event in the code was going, you already have an event scheduled
and as such the second event does not overwrite it. Leaving
no code to actually start the whole processing. There are probably
other cli iterations that will cause this fun as well, but I'm
not going to spend the time sussing them out at the moment.

Problem:
Delay in ospfv3 route installation when area gets converted to regular
from NSSA.
RCA:
when area gets converted from NSSA to normal the type-7(NSSA_LSAs)
gets flushed from the area, as a result the external routes
learnt from these type-7s gets removed. Once the area is moved
to nomral the type 5 lsas needs to flooded through the area
so that routes are re-learnt. however there is a delay in
flooding of these routes until these routes are refreshed.
Due to this there is delay installation of these routes.
Fix:
The Fix involves refreshing of the type 5 lsas once the area
is changed from nssa to regular area.
