lib: disable xref ELF note on mips64el
mips64el does not have a 64-bit PC-relative relocation, which is needed
to emit the ELF note for xrefs. Disabling the ELF note means clippy
takes the fallback path using section headers, so everything does still
work (... unless you strip the section headers.)

zebra: do not load/store wider-than-ptr atomics
Most 32-bit architectures cannot do atomic loads and stores of data
wider than their pointer size, i.e. 32 bit. Funnily enough they
generally *can* do a CAS2, i.e., 64-bit compare-and-swap, but while a
CAS can emulate atomic add/bitops, loads and stores aren't available.
Replace with a mutex; since this is 99% used from the zserv thread, the
mutex should take the local-to-thread fast path anyway. And while one
atomic might be faster than a mutex lock/unlock, we're doing several
here, and at some point a mutex wins on speed anyway.
This fixes build on armel, mipsel, m68k, powerpc, and sh4.

netlink_route_multipath_msg_encode checks whether the local kernel
supports NextHop Netlink message and doesn't send the message if the

kernel dataplane and FPM shares the same code. However, for the FPM,

bgpd: bgp_connected_add memory was being leaked in some cases
On shutdown, bgp calls an unlock for the bnc connected table,

only ever called on shutdown, so we know that bgp is going
away. The refcount for the connected data can be more than
1. Let's not worry about the refcount on shutdown and
just delete the nodes instead of leaving them around.

bgpd: static routes are leaked on shutdown
Shutdown of bgp results in both the bgp_path_info,
bgp_dest and bgp_table's not being freed because
the bgp_path_info remains locked.
Effectively static routes are scheduled for deletion but bgp_process
skips the work because the work queue sees that the bgp router
is marked for deletion. Effectively not doing any work and leaving
data on the floor.
Modify the code when attempting to put into the work queue to
notice and not do so but just unlock the path info.
This is effectively the same as what goes on for normal peering
as that it checks for shutdown and just calls bgp_path_info_free
too.

debian, redhat: updating changelog for new release
8.4 Release Overview
- New BGP [command](https://docs.frrouting.org/en/latest/bgp.html#clicmd-neighbor-A.B.C.D-X-X-X-X-WORD-soo-EXTCOMMUNITY) (`neighbor PEER soo`) to configure SoO to prevent routing loops and suboptimal routing on dual-homed sites.
- Command `debug bgp allow-martian` replaced to `bgp allow-martian-nexthop` because previously we allowed using martian next-hops when debug is turned on.
- Implement `BGP Prefix Origin Validation State Extended Community` [rfc8097](https://datatracker.ietf.org/doc/rfc8097/)
- Implement `Route Leak Prevention and Detection Using Roles in UPDATE and OPEN Messages` [rfc9234](https://datatracker.ietf.org/doc/rfc9234/)
- BMP L3VPN support
- PIMv6 support
- MLD support
- New [command](https://docs.frrouting.org/en/latest/basic.html#clicmd-allow-reserved-ranges) to enable using reserved IPv4 ranges as normal addresses for BGP next-hops, interface addresses, etc.
- As usual, lots of bugs and memory leaks were fixed \m/
