We need to know if they've sent us their sigs message yet. Ideally, we'd
be able to check the 'finalness' of the PSBT, however if the peer
doesn't have any inputs to the channel this doesn't work.
Back in the days before dual-funding, the `channel` struct on subd was
only every one type per daemon (either struct channel or struct
uncommitted_channel)
The RBF requirement on dualopend means that dualopend's channel,
however, can now be two different things -- either channel or
uncommitted_channel.
To track the difference/disambiguate, we now track the channel type on a
flag on the subd. It gets updated when we swap out the channel.
This will make it possible to do RBF, since we can re-start the opening
process in dualopend while waiting for lock-in.
Note the new channel states are being used, DUALOPEND_INIT and
DUALOPEND_AWAITING_LOCKIN, to differentiate from openingd/channeld opens
v2 channel opens are going to happen over in dualopend. In order
to make sure that these don't end up in the wrong place/to keep track of
the difference between "waiting for sigs" and "have merely initiatlized
a channel", we add two new states to the channel state machine.
A channel that 'originates' in dualopend will only ever arrive at
channeld in the state CHANNELD_NORMAL.
Since this all stays in dualopend/dual_open_control, we can hold
onto the openchannel_signed command to wait for a response here locally.
Previously we were splitting across the channeld/openingd boundary.
We used this for dual funded opens, to track the receipt of signatures.
We're moving all of this over to dualopend now, however, so we no longer
need the PSBT in channeld.
This is fixed when payload is freed, but I noted a leak in the case of
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
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).
