IPv6: Add 'autoconf' and 'disable_ipv6' module parameters
Add 'autoconf' and 'disable_ipv6' parameters to the IPv6 module.
The first controls if IPv6 addresses are autoconfigured from
prefixes received in Router Advertisements. The IPv6 loopback
(::1) and link-local addresses are still configured.
The second controls if IPv6 addresses are desired at all. No
IPv6 addresses will be added to any interfaces.
