Add support for SRv6 Node MSDs as per RFC 9352 section #4.
There are four types of SRv6 MSDs:
* Maximum Segments Left MSD Type
* Maximum End Pop MSD Type
* Maximum H.Encaps MSD Type
* Maximum End D MSD Type
These SRv6 Node MSDs are advertised in the Node MSD Sub-TLV, a Sub-TLV
of the Router Capabilities TLV.
This commit adds `struct isis_srv6_msd` data structure, which represents
the SRv6 MSDs advertised in the Node Sub-TLV.
This commit also adds the `struct isis_srv6_msd` to
`struct isis_router_cap`, a data structure representing the Router
Capabilities TLV.

Pass through a bunch of BGP_EVENT_ADD's and make
the code use a proper connection instead of a
peer->connection. There still are a bunch
of places where peer->connection is used and
later commits will probably go through and
clean these up more.

Modify all the receive functions to pass around the actual
connection being acted upon. Modify the collision detection
function to look at the possible two connections.

Modify bgp_fsm_change_status to be connection oriented and
also make the BGP_TIMER_ON and BGP_EVENT_ADD macros connection
oriented as well. Attempt to make peer_xfer_conn a bit more
understandable because, frankly it was/is confusing.

The usage of BGP_EVENT_FLUSH is unnecessarily abstracting the
call into event_cancel_event_ready and in addtion the macro
was not always being used! Just convert to using the actual
event_cancel_event_ready function directly.

Only attempt to install in netlink iprules that include supported
actions; ignore requests with actions that aren't supported by
netlink.

Currently evpn passes into bgp_path_info_cmp the pfx_buf
uninitialized. The bgp_path_info_cmp functionality actually
expects this value to be initialized. Additionally the
evpn section of bgp_path_info_comp was resetting the
new_buf and exist_buf values that were already being
set above to the same values if !debug was on( which
precluded it ever from happening )

... by converting the hash table to a typesafe hash.
Honestly I was just looking around for things to convert to the typesafe
hash table code, but then I noticed that cpu_record_clear() deletes
items from inside the hash_iterate() callback :(

This is noted in doc/developer/lists.rst, but judging by the previous
commit that's not where people look for this thing. Let's try a comment
in the header file.

This reverts commit 72eae2c3cb.
`frr_each_const(X, ...)` is not needed since it is the same as
`frr_each(X_const, ...)`.
The fact that it wasn't properly set up for clang-format, and that then
work-arounded with "clang-format off" is all the more reason to not do
this.

If the kernel sends us bad data then the kind_str
will be NULL and a later strcmp operation will
cause a crash.
As a note: If the kernel is not sending us properly
formated netlink messages then we got bigger problems
than zebra crashing. But at least let's prevent zebra
from crashing.

The `-disable-rr-semantics` or `--enable-rr-senamtics` configure
option is never used. Let's just remove it.
