* fhandler_procnet.cc (get_scope): New static function to evaluate 

scope.
	(dad_to_flags): New static array to convert Windows DAD state to
	Linux values.
	(format_procnet_ifinet6): Drop asking for IfIndex, just use Ipv6IfIndex.
	Use get_scope and dad_to_flags to generate more accurate linux-like
	output.
