Don't cache data from non-recursive nameservers, since it
may erroneously look like a valid CNAME to a non-exitant
name. Thanks to Ben Winslow for finding this.
Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
on exacly one interface and --bind-interfaces is set. This
makes the OpenStack use-case of one dnsmasq per virtual
interface work. This is only available on Linux; it's not
supported on other platforms. Thanks to Vishvananda Ishaya
and thr OpenStack team for the suggestion.
