sendonionmessage is going to be the new one, and do much *less*.
As this is an internal experimental-only API, no deprecation cycle
required.

result should *always* be an object. This allows it to add fields
without breaking the API. A command which returns "result" as a
string is living in sin.
This changes one of the two callers of "command_success_str".

Since plugins will start sending them soon, and they are likely to get
it wrong sometimes, be a bit more lenient, warn them in the logs
instead and then make sure it doesn't accidentally work anyway.
We will eventually start emitting and dispatching custom notifications
from plugins just like we dispatch internal notifications. In order to
get reasonable error messages we need to make sure that the topics
plugins are asking for were correctly registered. When doing this we
don't really care about whether the plugin that registered the
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.
You still shouldn't do this (you could get some transient failures),
but at least you have a decent chance if you reinstall over a running
daemon, instead of getting confusing internal errors if message
formats have changed.
Changelog-Added: lightningd: we now try to restart if subdaemons are upgraded underneath us.

Fixes: #4346
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`.
We consolidate to the latest/singular RFC patch for dual-funding, so
there's just a single patchfile for the change. Plus we move back to the
opener setting the desired feerate, the accepter merely declines to
participate if they disagree with the set rate.
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.

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.

Changelog-Added: plugins: plugins can now disable themselves by returning `disable`, even if marked important.
This avoids a footgun where they create an offer then we can't create
the invoice because they don't have a converter plugin.

A fractional satoshi value isn't really useful; rounding up loses
precision but that's why you called "whole satoshi", wasn't it?
Changelog-Changed: pyln-client: Millisatoshi has new method, `to_whole_satoshi`; *rounds value up* to the nearest whole satoshi
We need to use it for the 'df_accepter' plugin, so we get the feerate
correct.
Changelog-Added: pyln-client: `fundpsbt`/`utxopsbt` now support `min_witness_weight` param
"multi" means that specifying a parameter twice will append, not override.
Multi args are always given as a JSON array, even if only one.

Changelog-Added: Plugins: new "multi" field allows an option to be specified multiple times.
If we're already attempting to connect to a peer, we would ignore
new connection requests. This is problematic if your node has bad
connection details for the node -- you can't update it while inflight.
This patch appends new connection suggestions to the list of connections
to try.
Fixes#4154
We let the plugin decide what feerate to accept/whether or not to add
funds to the open. To aid this decision, we also send the plugin what we
(c-lightning) currently have as our max and min acceptable feerates.
We also now use these as our default for max/min acceptable feerate
range when sending an openchannel offer to a peer.
In the future, it might be a good idea to make these more easily
changeable, either via a config setting (?) or a command param.
