1) networkBuildDnsmasqArgv() = all uses of ipdef are protected from

    with DHCP info (or the first IPv4 address if none of them have any
    dhcp info).

2) networkStartDhcpDaemon() = if the loop looking for an ipdef with
    DHCP info comes up empty, we then grab the first IPv4 def from the
    list. Also, instead of returning if there are no IPv4 defs, we just
    return if there are no IP defs at all (either v4 or v6). This way a
    network that is IPv6-only will still get dnsmasq listening for DNS
    queries.

3) in networkStartNetworkDaemon() - we will startup dhcp not just if there
    are any IPv4 addresses, but also if there are any IPv6 addresses.

The comment is now out-of-date.

ACK with that nit fixed.

FIxed and pushed. Thanks!
