Implement actions on ip6addr, gatewayip6, serverip6 varaibles.
on_ip6addr - convert IPv6 string addr to struct ip6_addr
on_gatewayip6 - convert IPv6 string addr to struct ip6_addr
on_serverip6 - convert IPv6 string addr to struct ip6_addr
Series-changes: 3
- Removed memory allocation
- Substituted -1 for error code
