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.
