* bgp_route.h: (struct bgp_info) add a new flag, BGP_INFO_REMOVED.
BGP_INFO_VALID is already overloaded, don't care to do same thing
to STALE or HISTORY.
* bgpd.h: (BGP_INFO_HOLDDOWN) Add INFO_REMOVED to the macro, as a
route which should generally be ignored.
* bgp_route.c: (bgp_info_delete) Just set the REMOVE flag, rather
than doing actual work, so that bgp_process (called directly,
or indirectly via the scanner) can catch withdrawn routes.
(bgp_info_reap) Actually remove the route, what bgp_info_delete
used to do, only for use by bgp_process.
(bgp_best_selection) reap any REMOVED routes, other than the old
selected route.
(bgp_process_rsclient) reap the old-selected route, if appropriate
(bgp_process_main) ditto
(bgp_rib_withdraw, bgp_rib_remove) make them more consistent with
each other. Don't play games with the VALID flag, bgp_process
is async now, so it didn't make a difference anyway.
Remove the 'force' argument from bgp_rib_withdraw, withdraw+force
is equivalent to bgp_rib_remove. Update all its callers.
(bgp_update_rsclient) bgp_rib_withdraw and force set is same as
bgp_rib_remove.
(route_vty_short_status_out) new helper to print the leading
route-status string used in many command outputs. Consolidate.
(route_vty_out, route_vty_out_tag, damp_route_vty_out,
flap_route_vty_out) use route_vty_short_status_out rather than
duplicate.
(route_vty_out_detail) print state of REMOVED flag.
(BGP_SHOW_SCODE_HEADER) update for Removed flag.
