Implement '--redirect-gateway ipv6'
Add "ipv6" and "!ipv4" sub-options to "--redirect-gateway" option.
This is done in the same way as in the OpenVPN 3 code base, so
"--redirect-gateway ipv6" will redirect both IPv4 and IPv6 - if you
want v6-only, use "--redirect-gateway ipv6 !ipv4".
The actual implementation is much simpler than for IPv4 - we just
add a few extra routes to the route_ipv6_option_list and leave it to
init_route_ipv6_list() to figure out whether there is an overlap with
IPv6 transport, and if yes, insert a host route to the VPN server
via the current IPv6 default gateway.
