As requested by @shesek: it's weird to fail if they ask for the exact
same thing (which is quite possible, since offers don't expire by
default).
And add a new "created" field so they can tell if they have an old
one.

We don't support it (yet), but update the spec to include it.
We include the previous field (recurrence_signature) as a shim for the
moment, for compat with existing nodes. It's ugly, but next release
we'll stop *sending* it, then finally we'll stop accepting it!

Changelog-EXPERIMENTAL: BOLT12 offers can now be unsigned, for really short QR codes.
We used to only set it for single-use offers (where it's required),
but it's still interesting for multi-use offers, so let's keep it
there.
We also put this field in the documentation.

This is similar to the createinvoice API, except we don't need to save
invoice requests in the database. We may, however, have to look up
payment_key for recurring invoice requests, and sign the message with
the payment_key.

Invoices are signed with our own key, but we use a transient payer_key with a
tweak for invoice_requests (and refunds).
