Make normalize return multiple "hosts" (= reverse zones) when a non-octet boundary cidr is given. Added pkg/cidr package that holds the cidr calculation routines; felt they didn't really fit dnsutil. This change means the IPNet return parameter isn't needed, the hosts are all correct. The tests that tests this is also removed: TestSplitHostPortReverse The fallout was that zoneAddr _also_ doesn't need the IPNet member, that in turn make it visible that zoneAddr in address.go duplicated a bunch of stuff from register.go; removed/refactored that too. Created a plugin.OriginsFromArgsOrServerBlock to help plugins do the right things, by consuming ZONE arguments; this now expands reverse zones correctly. This is mostly mechanical. Remove the reverse test in plugin/kubernetes which is a copy-paste from a core test (which has since been fixed). Remove MustNormalize as it has no plugin users. This change is not backwards compatible to plugins that have a ZONE argument that they parse in the setup util. All in-tree plugins have been updated. Signed-off-by: Miek Gieben <miek@miek.nl>
