an invalid payload:

Our new "decode" command will also handle bolt11. We make a few cleanups:
1. Avoid type_to_string() in JSON, instead use format functions directly.
2. Don't need to escape description now that JSON core does that for us.

The previous onion_message code required a confirmed, not-shutting-down
channel, not just a connection. That's overkill; plus before widespread
adoption we will want to connect directly as a last resort.

Changelog-Added: JSON-RPC: `invoice` now takes an optional `cltv` parameter.
This makes for more useful errors. It prints where it was up to in
the guide, but doesn't print the entire JSON it's scanning.

Interestingly, we required that "sendrawtx" include "errmsg" field even
on success, otherwise we crashed in broadcast_remainder.
We only actually insist on an "errmsg" if success is false. And this
logic here is weird (the !success) was added by darosior in
947f5ddde1, which makes the msg checks redundant.

A user reported that it is sometimes cumbersome to search an invoice
based on the payment hash or the bolt11 string in the full list, which
may be required when we don't have the label available.
This adds support for querying / filtering based on the `payment_hash`
or `bolt11` string.
Changelog-Added: JSON-RPC: `listinvoices` can now query for an invoice matching a `payment_hash` or a `bolt11` string, in addition to `label`
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

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

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.

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.

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.

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).

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.
