`"deprecated": true` is obsolete; we don't document them anyway.
Where it would have otherwise changed the GRPC wrappers, I actually put the
version number in.
We allow "listchannels" to have "satoshis" since we have some tests
that run in deprecated-api mode.

If we have conditional fields, we often set `additionalProperties` `true`
at the top-level, but then we have to make sure to cover all the possible
combinations in conditionals, so unintended additions don't appear.
This revealed missing fields in delinvoice, for example.
