This makes use of the constant defined in the previous commits to more
accurately detect plaintext, encrypted, and invalid seeds. We now error
on invalid seeds.

This avoids duplication of both logic and error-prone values, such as
the salt. Grouping all hsm encryption logic into a public API will also
allow us to fuzz it.

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).

1. Hoist 7200 constant into the bolt12 heade2.
2. Make preimage the last createinvoice arg, so we could make it optional.
3. Check the validity of the preimage in createinvoice.
4. Always output used flag in listoffers.
5. Rename wallet offer iterators to offer_id iterators.
6. Fix paramter typos.
7. Rename `local_offer_id` parameter to `localofferid`.
8. Add reference constraints on local_offer_id db fields.
9. Remove cut/paste comment.
10. Clarify source of fatal() messages in wallet.

This takes an unsigned bolt11 (or bolt12 if EXPERIMENTAL_FEATURES) string
and signs it and puts it in the database.
The invoice command could now be moved out to a plugin, in fact.

This is for offers which have `send_invoice`: we need to associate the
payment with the original offer, in (the usual) case where it is a single
use offer. We mark it used when it's paid, to avoid a race.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This allows us to mark an offer used when an invoice derived from it
is paid, and importantly, avoid any other invoices for the offer being
paid.

"multi" means that specifying a parameter twice will append, not override.
Multi args are always given as a JSON array, even if only one.

Changelog-Added: Plugins: new "multi" field allows an option to be specified multiple times.
This was fixed in 0.8.2.

Changelog-Removed: plugins: options to init are no longer given as strings if they are bool or int types (deprecated in 0.8.2).
Still asserts that it's the standard size, but makes it a dynamic
member. For simpliciy, changes the parse_onionpacket API (it must be
a tal object now, so we might as well allocate it here to catch all
the callers).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We were masquerading errors when parsing the request by reporting only
a bogus malformed `id` field in the response, when the real issue was
that we were unable to parse the request in the first place (which
caused the null-id error to be returned).
Fixes#4238
Only way to be sure that plugins don't accidentally respond to onion_message
sent via reply path from another message (which would potentially leak our
identity!).
To quote BOLT #7 (Onion Messages) in the offers PR:
```markdown
The reader:
- MUST ignore any message which contains a `blinding` which it did not expect, or does not contain
a `blinding` when one is expected.
...
`blinding` is critical to the use of blinded paths: there are various
means by which a blinded path is passed to a node. The receipt of an
expected `blinding` indicates that blinded path has been used: it is
important that a node not accept unblinded messages when it is expecting
a blinded message, as this implies the sender is probing to detect if
the recipient is the terminus of the blinded path.
Similarly, since blinded paths don't expire, a node could try to use
a blinded path to send an unexpected message hoping for a response.

Changelog-Changed: JSON-RPC: invalid UTF-8 strings now rejected.
This effectively reverts ac93b780d5.
Christian points out that plugins need time before we deprecate
the old options (probably 6 months) as they need to work with
both old and new.

Incase we have been offline while a channel was force closed on us we
now set the 'closer' to 'remote' instead of null because this is by far
the most probable reason.
Changelog-None
This adds a missing plugins_send_getmanifest() call in the rescan function
that lead to a RPC hangup. Not sure though if this is the proper fix.
Changelog-None
We previously registered hooks up in who-replies-to-getmanifest-first
order, but then if any had dependencies it would scatter that order.
This allows users to manually set dependencies developers have
forgotten by specifying the plugins manually in their configuration or
cmdline. This was an excellent consideration by @mschmook.
