📄 Description

The main motivation behind these changes is continuing to use BIND internally whilst enabling Cloudflare for public DNS. With that in mind, it is desirable to accept some records being un-syncable (e.g. SRV, which can be useful internally but non-critical externally), and to have 'magic' TTL values that are acceptable to use literally (0 in particular is notably unsuitable).
The other notable change is to support explicitly specifying the Origin of the zone file - this is significant if the BIND infrastructure imports the same definition in multiple origins.
There is also some tidying of PrintUsage, to make it more helpful and consistent.
