It only works on BOLT11, and has long been replaced by the more
generic "decode".
Removing it will stop the confusion!
(Note: documentation claims it was introduced in 23.08, but that was
wrong, as it's been in CLN since the beginning).

Based on the patch by bstin <barry.github@capsmx.com>, which added a separate command,
this simply extends "generatehsm" to allow more options.

Changelog-Added: hsmtool: generatehsm can run non-interactive, taking options on the cmdline.

And we hook in the replay watch code.

Changelog-Fixed: `onchaind` can miss conclusion of final txs in some cases, will now replay independently.
And use it for `exposesecret-passphrase`. This is probably overly
cautious, but it makes me feel a little better that we won't leak it
to someone with read-only access.

Being able to back up the hsm_secret is critical, but you cannot do
this through a UI, because of course we do not allow such access.
People have lost funds because they didn't back up.
This allows access to the hsm_secret if you use a password set in the
config file. (If it's not set, the command does not work). This is a
compromise, of course.
Changelog-Added: `exposesecret` command for encouraging hsm_secret backups.

This takes an {payment_id} and {description}.
It looks for all chain + channel events that match
that {payment_id} and updates the description for those events.
We return all the updated events. If no events are updated, an empty
list is returned.
Changelog-Added: PLUGINS: bookkeeper has a new RPC `bkpr-editdescriptionbypaymentid` which will update the description for any event with matching payment_id
This is the sister command of addpsbtoutput.
Adds inputs equal to or greater than the amount requests, reservers them, and reports important information back out to the user.
Changelog-Added: New low-level RPC command addpsbtinput to fund PSBTs directly and help with complex splices & dual-opens.
The ability to stfu channels in bulk is required to do complex multi channel operations. When stfu’ing in this manner, the available funds at the moment of stfu is returned to the user.
In order to cancel the stfu we also add a bulk tx_abort command.
Changelog-Added: `stfu_channels` and `abort_channels` are added for bulk multi-channel splice commands. These allow the user to pause (and resume) multiple channels in place.
This is needed to all multi-channel splices. When channeld can return the signatures to the user (based on signing order precedent), it now does from splice_update.
Additionally, we move sending of the initial psbt from splice_init down to splice_update. This is also necessary for correct psbt diff detection during multi-channel splices.
Changelog-Changed: splice_update can in some cases now return the remotely partiall signed psbt to the user, if so `signtures_secured` will be true.
This lets you place annotated biases on channels, to influence routing.
Uses include avoiding TOR nodes, slow channels or other local preferences.

Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:
1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.

4. Remove command_deprecated_in_nocmd_ok.

Note the impedence mismatch between sendpay and getroutes: we have to shift
amounts and delays by 1.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Our gossmap_store uncompresser generates nodeids with well-known
privkeys, so we can decrypt and respond to HTLCs sent to such nodes.
By replacing channeld with a fake, we can connect a node to another
node, but then once the channel is established, allow payments to be
sent into the generated network, and respond appropriately.
This minimal version handles MPP timeouts, but doesn't insert any
delays or runtime capacity for channels.
