This matters: if we connected, the address is probably usable for future connections.
But if they connected, the port is probably not (but the IP address may be).
Changelog-Added: JSON-RPC: `connect` returns "direction" ("in": they iniatated, or "out": we initiated)
Changelog-Added: plugins: `peer_connected` hook and `connect` notifications have "direction" field.

Otherwise, we might find an address other than the one given and

In particular, txprepare gives us a nice way to get a valid PSBT for
testing.

Changelog-Added: JSON-RPC: `txprepare` and `withdraw` now return a `psbt` field.
Requiring the user to calculate the txid of the PSBT is a horrible, bad,
no-good idea.
Doesn't deprecate yet, so I can test that this path works while
multifundchannel still uses it.

Changelog-Added: lightningd: experimental-shutdown-wrong-funding to allow remote nodes to close incorrectly opened channels.
Changelog-Added: JSON-RPC: close has a new `wrong_funding` option to try to close out unused channels where we messed up the funding tx.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It's not unheard of for people to give the wrong funding tx to us,
getting their funds stuck. Interestingly, we can allow mutual close
using a different txid and output number as long as they (solely)
funded the channel, and the channel hasn't been used.
This defines a "play area" feature to do just that.

Allows us to clean up an in-progress open that we won't be completing
Changelog-Added: EXPERIMENTAL JSON-RPC: Permit user-initiated aborting of in-progress opens. Only valid for not-yet-committed opens and RBF-attempts
The `rbf_channel` hook uses `our_funding_msat`, which is a nicer
and more easily understood than the `openchannel2`
`accepter_funding_msat`.
This updates the `openchannel2` hook to use the same nomenclature as
`rbf_channel`.
Users have no idea what they would pay for unilateral closes.
At least this gives them a clue!

We were always prefixing the `message` field with the internal type
prefix 0x0407, followed by the length prefix. Neither is needed since
the type being constant is of no interest to the plugin and the length
being implicit due to the JSON-encoding.
Reported-by: Ilya Evdokimov
Changelog-Fixed: plugin: The `custommsg` hook no longer includes the internal type prefix and length prefix in its `payload`
Changelog-Deprecated: plugin: The `message` field on the `custommsg` hook is deprecated in favor of the `payload` field, which skips the internal prefix.
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.

network was missing regtest as an option.
The example was too simple, so I added a second one so show how the k option works.
The explanation of how k works should let the user know that in some cases lightningd will interpret the position of an argument which can lead to a weird response from lightningd.
let the users know that using null is not encouraged
@cdecker said "I think we should definitely not encourage null, since that is very brittle and forces us to keep argument ordering, and deprecating arguments is practically impossible."
In the case where you want a PSBT and also want the output to be added
as a change address, use `excess_as_change` = true.
Generates a change address to use. If you want to pay the excess
elsewhere, you will have to add separately.
Changelog-Added: JSON-RPC: Add new parameter `excess_as_change` to fundpsbt+utxopsbt

Indeed, we close stdout, and it ends up being reused for some plugin.
But the real problem is that we log to stdout by default, which doesn't
make sense. If they really want to discard logs, they can use
--log-file=/dev/null.

We split `send_invoice` offers inoo offerout (for want of a better name).
This simplifies the API.
Also took the opportunity to move the `vendor` tag to immediately
follow `description` (our tests use arguments by keywords, so no
change there).

Needed for v2 of channel opens, where the minimum weight is 110; a

establish a floor for this case.

tools: Add `generatehsm` method to hsmtool to derivate BIP32 seeds from a
mnemonic using the BIP39 standard.
The new method uses libwally for the BIP39 to BIP32 derivation. It also
fails if an hsm_secret file already exists, so we do not overwrite
someone else's wallet without noticing.
It allows the use of passphrases, the ECHO mode in the terminal is
disable for higher security.
It currently supports "en", "es", "fr", "it", "jp", "zhs", "zht".
Changelog-Added: hsmtool: `hsm_secret` generation from a seed-phrase following BIP39.
We previously registered hooks up in who-replies-to-getmanifest-first

This allows users to manually set dependencies developers have

Technically there *are* two feerates that we need to know:
- the feerate to use for the funding transaction, and
- the feerate to tell our peer to use for our commitment txs/htlc txs
As written, `multifundchannel` uses the same feerate for both. This
optional parameter will allow us to differentiate between the two, which
will be exceedingly handy for anchor output worlds. ;)
FIXME: test this
Changelog-Added: JSON API: `multifundchannel` has a new optional argument, 'commitment_feerate', which can be used to differentiate between the funding feerate and the channel's initial commitment feerate
This will allow us to build complex, multi-peer transactions, with
easeTM!
Changelog-Added: EXPERIMENTAL, Plugins: `openchannel_peer_sigs` notification, which contains a peer's signatures for the funding transaction (`opt_dual_fund`)
This is handy/necessary for getting multifundchannel to work, as we need
to know what output to tell all the other peers about.
Changelog-Added: Experimental!! JSON-RPC: openchannel_init returns a field `funding_serial` that indicates the serial_id of the funding output in the provided PSBT
`openchannel_signed` and `openchannel_update` which allow a user to
continue a openchannel or kick off the completion of a openchannel.
`openchannel_update` should be called until it returns with
`commitments_secured`.
There are 3 commands for opening a channel with dualfunding.
`openchannel_init` is the first of these.
It initializes the open-channel dialog, and stops once we've run out of
updates (input/outputs) to send to the peer.
Finally, extends the 'close_to' functionality up to the flagship 'open a
channel' command.
Changelog-Added: JSON-API `fundchannel` now accepts an optional 'close_to' param, a bitcoin address that the channel funding should be sent to on close. Requires `opt_upfront_shutdownscript`
