Currently the AIGP is always incremented when a route with the
attribute is advertised. That is incorrect when the nexthop is
unchanged, as is commonly the case in route reflection.
Adjust the AIGP for propagation only when the nexthop is set
to ourselves.

added bmp bgp peer for vrfs
added peer up vrf in bmp peer up state
added vrf state in bmpbgp
added safe bmp_peer_sendall : bmp_peer_sendall_safe
changed bgp_open_send to call new bgp_open_make
bgp_open_make creates a bgp open packet, now used in bmp for peer up vrf
added hook and call to bgp instance state
vrf peer state is recomputed when interfaces (including vrf itf) go up / down
and when it gets created or removed

When trying to track down a MTYPE_TMP memory leak
it's harder to search for it when you happen to
have some usage of ttable_dump. Let's just give
it it's own memory type so that we can avoid
confusion in the future.

Unconfiguring the send-experimental stats in BMP has no effect
on the current behavior.
Fixes this by swapping the configuration boolean.

Some wireshark versions can not decode the experimental
bmp stat code. This may also be the case for some collectors.
Add a vty command to be able to disable bmp to sending
those values.

set field peer bgp id to the peer's remote id in every case except loc-rib (RFC9069 case) in which we put the bgp instance's router-id if available or 0-filled if not available
set field peer asn to local primary bgp asn in case of loc-rib instance (RFC9069) else it's set to the peer's asn
set field peer address to 0 in loc-rib instance (RFC9069 case) and to the peer's address in other cases

This is based on @donaldsharp's work
The current code base is the struct bgp_node data structure.
The problem with this is that it creates a bunch of
extra data per route_node.
The table structure generates ‘holder’ nodes
that are never going to receive bgp routes,
and now the memory of those nodes is allocated
as if they are a full bgp_node.
After splitting up the bgp_node into bgp_dest and route_node,
the memory of ‘holder’ node which does not have any bgp data
will be allocated as the route_node, not the bgp_node,
and the memory usage is reduced.
The memory usage of BGP node will be reduced from 200B to 96B.
The total memory usage optimization of this part is ~16.00%.

As part of the conversion to a `struct peer_connection` it will
be desirable to have 2 pointers one for when we open a connection
and one for when we receive a connection. Start this actual
conversion over to this in `struct peer`. If this sounds confusing
take a look at the bgp state machine for connections and how
it resolves the processing of this router opening -vs- this
router receiving an open. At some point in time the state
machine decides that we are keeping one of the two connections.
Future commits will allow us to untangle the peer/doppelganger
duality with this abstraction.
