	* bgp_aspath.c: (aspath_highest) new, return highest ASN in an
	  aspath.
	* bgp_route.c: (bgp_peer_count_walker) new, do the walk done
	  in bgp_peer_counts as a thread.
	  (bgp_peer_counts) move walk to previous and call it via
	  thread_execute so this RIB walk shows up in thread stats.
	  (bgp_table_stats) New, gather some statistics for a given
	  RIB.
	  (bgp_table_stats_walker) New, RIB walker thread for former.
	  (bgp_table_stats_vty) Parsing front-end for 'show bgp ...',
	  useful model for future rationalisation of 'show ... bgp'.
	  (bgp_route_init) Add new RIB stats commands.
