Improve generic ipv4+ipv6 support in libbb.
Convert telnet to it. Now this works: telnetd -b [::1]:1234 - bind to IPv6 non-standard port telnet [::1]:1234 - connect to IPv6 non-standard port telnet ::1 1234 - same This does not require ANY ipv6-specific code in applets (no struct sockaddr_in6. In fact, no sockaddr_in, too).
