6aa520bb9b lightningd: remove sendonionmesage parity hack.
offers contain an x-only pubkey: to route to them to need to know the
02 vs 03 prefix.  If they're in the gossmap it's easy, but if they're
a directly-connected peer it's harder.  We used to have
sendonionmessage tweak the key if it found a peer with the matching
key, but this was always a hack.

It turns out that we try to connect to the node anyway, which is
a noop if it's already connected.  So try connecting to the other
parity if the first one fails.

Also, this registers when we fail to connect, and returns an error
rather than waiting for timeout.

fe86c117d9 datastore: turn keys into arrays
After some discussion with @shesek, and my own usage, we agreed that
a more comprehensive interface, which explicitly supports grouping,
is desirable.

Thus keys are now arrays, with the semantic that a key is either a
parent or has a value, never both.

For convenience in the JSON schema, we always return them as arrays,
though we accept simple strings as arguments.

*warning_capacity* is now the "even under best circumstances, we don't

warning_mpp_capacity was trying to say (no longer printed).

*warning_offline* and *warning_deadends* are only given if adding such
peers would have helped give capacity (i.e. not if *warning_capacity*
is set).  The new *warning_private_unused* tells you that we would
have sufficient capacity, but we refused to expose private channels.

Trying to put all the disconnect logic into the same path was a dumb
idea. If you asked to reconnect but passed in an 'unsaved' channel, we

Instead, we make a differentiation between "unsaved" channels
(ones that we haven't received commitment tx for) and handle the
disconnect for these separate from where we want to do a reconnect.

notification is still alive or not (it might have died, but
subscribers should stay up and running), so we keep a list of all
topics attached to the `struct plugins` which gathers global plugin
information.

006300ab96 lightningd: set "direction" correctly for connect which is already connected.
This means remembering the connection direction.  We also use the address to try
to reconnect, which we shouldn't bother with if they connect to us.

For peers from the database, we currently always save the addr: we shouldn't really
do this if they connected to us, since it's not useful for reconnecting (we don't
show the addr in JSON reply to listpeers unless we're connected, so it's only an
internal issue).  This is left for future work.

e59940eb61 plugin: Abort early if we have a misconfiguration in the plugins
We were reporting the failure immediately but still continuing with
the startup. This could happen if an important plugin ends up in a
race with another plugin (important or not) for a contended
resource (CLI option or RPC method name). We would eventually notice
that we were supposed to abort, but at that point we already processed
a couple of blocks, loaded the entire state, etc.

This just aborts early with a sane error message.

Changelog-Added: plugin: If there is a misconfiguration with important plugins we now abort early with a more descriptive error message.

21355edc43 plugin: Do not send the internal framed message over the wire
Looks like #4394 treated a symptom but not the root cause. We were
actually sending the message framed with the WIRE_CUSTOMMSG_OUT and
the length prefix over the encrypted connection to the peer. It just
happened to be a valid custommsg...

This fixes the issue, and this time I made sure we actually send the
raw message over the wire. However for backward compatibility we
needed to imitate the faulty behavior which is 90% of this patch :-)

Changelog-Fixed: plugin: `dev-sendcustommsg` included the type and length prefix when sending a message.

We weren't sending a channel_open notification for dual-funded channels.

This is only sent for the 'accepter' side. We send it as soon as both
funding_tx sigs have been exchanged, even though it's possible the
funding transaction might be published without this having been the case.

Since we fail the channel if this happens, only notifying for good/valid
channels reaching the broadcast state is the right way to handle this.

bf49bcfa90 subd: keep track of 'channel's type
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.

695a8bd868 lightningd: split onion_message hook.
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.
