The DHCPv6 support includes IPV6 dhcp-range and dhcp-host for one
IPv6 subnetwork on one interface. This support will only work
if dnsmasq version >= 2.64; otherwise an error occurs if
dhcp-range or dhcp-host is specified.
Essentially, this change provides the same DHCP support for IPv6
that has been available for IPv4.
With dnsmasq >= 2.64, support for the RA service is now provided
by dnsmasq (radvd is no longer used/started).
Dnsmasq 2.64 does contain the bugfixes released to DHCPv6 and
dnsmasq's handling of Router Advertisement.
Documentation has been updated to reflect the new support.
The network schema has been updated to reflect the new support.
