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!
