This will also change the requirements of whether or not a dnsmasq
restart or "refresh" (SIGHUP) is required when certain pieces of the
network definition are changed with virNetworkUpdate(), but that can be
submitted as a separate patch. (basically, things that used to require a
change on the commandline, but now only require a change in the conf
file, will no longer require a restart).

Submit it assuming that the patch *has* been applied. I think we do need
to make that change (adding "--interface"), but it needs to be
explicitly visible in a separate patch (and we need to do some testing
before pushing it).
