freebsd/usr.sbin/rtadvd/dump.c
Hajimu UMEMOTO fc35a81b09 - supported a string notation for xxflags.
- deprecate routes#N, as it is hard to keep consistency with
  rtprefixN.  accept any number of "rtprefix", "rtrefix0",
  ..., "rtprefix99".
- deprecate "addrs#N", as it is difficult for users to keep
  consistency with "addrN".
  accept 100 prefix info in maximum - like "addr", "addr0"
  ... "addr99".  WARNS=2 clean on netbsd.
  old configuration file should work just fine.
  behavior change:
  previously, we rejected "addrN" if there's "addr", and we rejected
  "addr" if there is "addrN".  now we accept both without problem.
- when an advertised prefix configured from the kernel has been added
  or invalidated, notice the change in a short delay.
- when invalidating a prefix, do not bark even if there is
  inconsistency about prefix lifetimes.
- wrap more specific route info code into ROUTEINFO.
