This patch from Bart Visscher <magick@linux-fan.com> adds
IPV6 support to busybox. This patch does the following:
* Add IPv6 support to libbb
* Enable IPv6 interface address display
* Add IPv6 config option
* Adds ping6, an adaptation of the ping applet for IPv6
* Adds support routines for ping6:
- xgethostbyname2
- create_icmp6_socket
* Adds ifconfig support for IPv6
* Add support IPv6 to netstat
* Add IPv6 support to route
Thanks Bart!
