bgpd: Skip route clearing for peers that were never establishedWhen bgp_fsm_change_status() transitions a peer to Clearing or Deleted
state, it still unconditionally calls bgp_clear_route_all() which walks the
entire BGP table. For peers that were not in Established state (e.g.,
doppelganger peers from TCP collision resolution), this walk is pure overhead
The previous fix(e0ae285) uses peer->established which is a monotonically
increasing counter that is ...
bgpd: use bgp_node_match() instead of bgp_node_get() in aggregate countbgp_node_get() creates a transient node in the aggregate table for the
route prefix just to anchor a parent walk, which is wasteful.
bgp_node_match() does a longest-prefix match and returns only nodes
where aggregate data is actually present, without creating any new node.
Return early if bgp_node_match() returns NULL, meaning no covering
aggregate exists for the route prefix.

tests: Add topotest for BGP-LS SRv6 extensionsAdd a new topotest that validates BGP-LS SRv6 behavior end-to-end.
The test brings up an IS-IS SRv6 domain with a BGP-LS producer and
consumer, verifies session and capability negotiation, and checks that
the expected SRv6-related BGP-LS NLRIs and attributes are originated
and received correctly.
