MFC: Implement EDNS0 support, as EDNS0 support will be made mandatory for
IPv6 transport-ready resolvers/DNS servers.  Need careful configuration
when enable it. (default config is not affected).
See manpage for details.

  XXX visible symbol __res_opt() is added, however, it is not supposed to be
  called from outside, libc minor is not bumped.
