network: add support for DHCPv6 

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 for an IPv6 address.

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 also now provided
by dnsmasq (radvd is no longer used/started). (Although at least one
version of dnsmasq prior to 2.64 "supported" IPv6 Router
Advertisement, there were bugs (fixed in 2.64) that rendered it
unusable.)

Documentation and the network schema has been updated
to reflect the new support.

An IPv6 <code>host</code> element differs slightly from that for IPv4:
there is no <code>mac</code> attribute since a MAC address has no

the name is the plain name of the client host sent by the
