qos-scripts: Add IPv6 support

This adds IPv6 support to qos-scripts for both tc/qdisc and the
iptables classification rules.  The tc/qdisc part is accomplished
by removing "protocol ip" from the tc command line, causing the
rule to be applied to all protocols.  The iptables part is
accomplished by adding each rule using both iptables and ip6tables.

This patch is based on previous work by Ilkka Ollakka and
Dominique Martinet.
