This is needed for the next patch, which does this from the peer_connected hook!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON-RPC: `sendcustommsg` can now be called by a plugin from within the `peer_connected` hook.
We keep the node_id, not a pointer to the peer.
This also means that it might have reconnected while we were in the hook, so make
sure we ignore the result if it's in state PEER_CONNECTED.
And remove the `tal_steal(peer, hook_payload)` which doesn't do anything: the
plugin_hook call steals hook_payload anyway!
Fixes: #5944
It's not likely but possible that the node's settings will shift btw a
start and an RBF; we persist the setting to the database so we don't
lose it.
Right now holding onto it forever is kind of extra but maybe we'll
reuse the setting for splices? idk.
Should this be a channel type??
`openchannel_init` takes a psbt, which we pipe over to dualopend
process.
If the peer requests that they'll only accept confirmed inputs, we need
to go validate those before we continue.
This wires up the harness for this (validation check yet tc)
technically we don't need this info after the channel opens, but for any
subsequent RBF (and maybe splice?) we need to remember what the
open/accept peer signaled
not amazing, since we'll probably call openchannel_update multiple
times per open, but this is the simplest way to confirm that we're
not sending unconfirmed outputs to peer.
This will save a lot of RPC ping/pong when plugins still need to iterate
both, `listpeers` and `listpeerchannels`. When `num_channels` is 0 they
can skip additional calls.
Changelog-Added: RPC `listpeers` output now has `num_channels`.
Though there's already a `createinvoice` command, there are usecases where a
user may want to sign an invoice that they don't yet have the preimage to. For
example, they may have an htlc_accepted plugin that pays to obtain the preimage
from someone else and returns a `{ "result": "resolve", ... }`.
This RPC command addresses this usecase without overly complicating the
semantics of the existing `createinvoice` command.
Changelog-Added: JSON-RPC: `signinvoice` new command to sign BOLT11
invoices.
This allows to accept safely long paths as options
and does not truncate them

In v0.11 (71f736678f) we changed lightningd to wait for gossipd to
acknowledge blocks before updating blockheight: this resolved a problem
which lnprototest had where it wanted to know when we'd fully digested
a block.
However, it broke the syncing case: until then we don't even tell
gossipd, so this stayed at zero. We should use the current blockheight
for that corner case!
Fixes: #5894
Changelog-Fixed: JSON-RPC: `getinfo` `blockheight` no longer sits on 0 while we sync with bitcoind the first time.

When a channel open fails, we use tx-abort instead of warning/error.
This means that the peer won't disconnect! And instead when a new
message arrives, we'll need to rebuild the dualopend subd (if missing).
Makes opens a bit easer to retry (no reconnect needed), as well as keeps
the connection alive for other channels we may have with that peer.
Changelog-Changed: Experimental-Dual-Fund: open failures don't disconnect, but instead fail the opening process

In various circumstances we can start a reconnection while one is
already going on. These can stockpile if the node really is unreachable.

The leak-detector can't find unconnected_htlcs_in on the stack and
incorrectly flags this as a leak. However, it is appropriately tal
allocated and freed.
Changelog-None
There were cases where address it's empty, and this cases are not right if the
field is considered optional.
This makes it required and add the field also when `--offline` is set.
Changelog-Changed: JSON-RPC: `getinfo` `address` array is always present (though may be empty)
We need to check if the key parameter is an empty array in
`listdatastore` as we do assume an array of at least length 1 in
`wallet.c:5306`.

Changelog-EXPERIMENTAL: JSON-RPC: `listtransactions` `channel` and `type` field removed at top level.
```
make check-source-bolt CHECK_BOLT_PREFIX="--prefix=BOLT-onion-message" BOLTVERSION=guilt/offers
```
Mainly textual, though I neatened the extra fields check for TLVs with
blinding, and implemented the "no other fields" requirement for
non-final onion message hops.

```
make check-source-bolt CHECK_BOLT_PREFIX="--prefix=BOLT-route-blinding" BOLTVERSION=guilt/offers
```
Other than textual changes, this does:
1. Ensures we put total_amount_msat in onion final hop (reported by @t-bast).
2. Require that they put total_amount_msat in onion final hop.
3. Return `invalid_onion_blinding` exactly as defined by the spec (i.e. less
aggressive when we're the final hop) (also reported by @t-bast, but I already
knew).

Changelog-EXPERIMENTAL: `offers` breaking blinded payments change (total_amount_sat required, Eclair compat)
You can use rs->nextcase, but we don't always keep that around, so
keep a flag in onion_payload.
We'll use this in the "do we need to return a blinded error code"
patch.

This will give the user an option to set a custom port when using
discovered IPs for node_announcents. Without this, only the selected
networks default port can used.
Changelog-Added: Adds --announce-addr-discovered-port config option to set custom port for IP discovery.
This switch was not doing anything useful anymore.
We deprecate it anyways to notify the user about the new switch.
Changelog-Deprecated: The old --disable-ip-discovery config switch
This adds the option to explicitly enable ip-discovery, which maybe
helpful for example when a user wants TOR announced along with
discovered IPs to improve connectivity and have TOR just as a fallback.
Changelog-Added: Adds config switch 'announce-addr-discovered': on/off/auto
After connecting 100,000 peers with one channel each (not all at
once!), we see various places where we exhibit O(N^2) behaviour.
Fix these by keeping a map of id->peer instead of a simple
linked-list.
