All the capabilities should be supported in 2.67.
Make this the minimum version, since even the oldest
distros we support have moved on:
Debian 8: 2.72
CentOS 7: 2.76
Ubuntu 18.04: 2.79

I think you actually want something like:
if (caps->version
< DNSMASQ_MIN_MAJOR * 1000000 + DNSMASQ_MIN_MINOR * 1000)
(or if you wanted to avoid giving this file the knowledge of how version
numbers are represented internally, you could #define
DNSMASQ_MIN_VERSION "2.67", then use virParseVersionString() to parse
that into an unsigned long, and then compare that result. That seems
like overkill though)
