We have a global JSON encoder hack, which means that any field ending in msat gets special treatment (so we can safely talk to lightningd, even if a field expects satoshi amounts, we are explicit). However, requests uses the JSON parser and DOES NOT want this conversion when sending it out as an HTTP response!
The simplest local fix we could find was Shahana's suggestion to iterate and covert away from Millisatoshi(): the reverse of what our JSON encoder does.

It already throws an exception or error, or decodes the JSON response:
we can simply pass it through.

Here, we split up what was "commit_received" into two phases:
- commit-ready, where we're about to send our commitment tx to
peer
- commit-received, when we've gotten the commitment tx from our
peer
This lets us do the right thing (as far as the spec is concerned) with
returning the correct 'next_funding_txid' on reconnect (later commits).

Changelog-Changed: Config: `large-channels` is now the default, wumbology for all.
Adding a fee offset as the channel opener reduces the likelihood of a
disconnect by the peer do to slight variation in feerate calculation
between nodes.
Changelog-Fixed: Some peer disconnects due to update_fee disagreements are avoided.
Looking through logs I was surprise to see:
```
lightningd-1 2023-10-26T03:42:36.824Z INFO lightningd: Sending 200000000msat over 1 hops to deliver 200000000msat
```
On a re-payment where we simply returned from sendpay immediately! Move that log to later.
We used to have "unsaved" payments: now we don't we can use
our normal "iterator" pattern rather than returning arrays.

The log messages were changed but the test fields weren’t updated, resulting in some test flakiness. Being more explicit with the log message we’re looking for should help.
Changelog-None
This means refactoring out some of the generic anchor info, from the
per-commitment-tx info (we can have at least two, perhaps more with
splicing!).

We try to use anchors to CPFP our own commitment, but what if they
get there first? We also need to use anchors on the commitment
txs they broadcast.

We had a complaint that you can't CPFP a mutual close, which you

We remove it from the pending_requests strmap before calling it,
so it doesn't get called again by destroy_plugin.

Now the internal code will generate a "PLUGIN_TERMINATED" response
when the plugin dies, we can handle it in plugin_hook.
But we can also simplify it by turning the snapshot of hooks into
a simple array: this means we are robust against any combination of plugins
exiting at any time.
Note: this reveals an issue with test_rpc_command_hook where we run
the request hook again (unexpectedly), so we disable that for the next
patch.

We had special code to fail a forwarded request, but not for an
internally-generated request. Instead, we should pretend the (dead)
plugin responded with a PLUGIN_TERMINATED error, and handle the
request through the normal paths.
This breaks the case where a plugin crashes (or stops itself) in a
hook, so we handle that next.
