It might be nice to let the bookkeeper keep track of external accounts
as well as the internal onchain wallet? To this end, we add some new
custom notifications, which the bookkeeper will ingest and add to its
ledger.
Suggested-By: @chrisguida
Changelog-Added: PLUGINS: `bookkeeper` now listens for two custom events: `utxo_deposit` and `utxo_spend`. This allows for 3rd party plugins to send onchain coin events to the `bookkeeper`. See the new plugins/bkpr/README.md for details on how these work!
This avoids globals (and means memleak traverses the variables!): we
only change over the test plugin though, to avoid unnecessary churn.

I was looking into using the `threading.Condition` but since we're
already rather heavily using callbacks, this allows us to stay
single-threaded, and not having to completely hook the `setconfig`
function.
Changelog-Added: pyln-client: Added a notification mechanism for config changes
We didn't actually *change* the value you'd see, when we got a setconfig call!
Changelog-Added: pyln-client: implement setconfig hook for plugins so you can see changes in `dynamic` options.

This means we can see the values in listconfigs, even if we haven't set
them yet.
In particular, we now see the following:
* autoclean-cycle.value_int=3600
* bitcoin-rpcclienttimeout.value_int=60
* bitcoin-retry-timeout.value_int=60
* funder-max-their-funding.value_str=4294967295sat
* funder-per-channel-min.value_str=10000sat
* funder-reserve-tank.value_str=0sat
* funder-fund-probability.value_int=100
Changelog-Changed: plugins: libplugin now shows plugin option default values (where they're non-trivial)

Listpeerchannels would update the local channel information setting the
liquidity in the outgoing channel to known_min=known_max=capacity,
when in fact it should be known_min=known_max=spendable.
These were deprecated in v22.08 (invoice hook) and v0.8 (htlc_accepted hook), and
marked EOL in v23.02.
*PLEASE* complain if this breaks things for you: it's kind of a test canary of
the deprecation system!

Changelog-Removed: Plugins: `invoice_payment` and `htlc_accepted` hook `failure_code` response (derepcated v22.08 and v0.8, EOL v23.02)
Since these worked in v23.08, we can't just rename them. So if they are
used and unclaimed, we should rename them internally (if they're claimed,
it's probably clightning-rest, and we should *NOT* touch them!).

Changelog-Deprecated: Plugins: `clnrest` parameters `rest-port`, `rest-protocol`, `rest-host` and `rest-certs`: prefix `cln` to them
And require --developer to use them.
Also refuse redirection to deprecated APIs if deprecated APIs are disabled!
Changelog-Removed: `dev-sendcustommsg` (use `sendcustommsg`, which was added in v0.10.1)

I added a plugin arg and was surprised that compile didn't break.
This is because typesafe_cb et al are conditional casts: if the type
isn't as expected it has no effect, but we're passing plugin_option() through
varargs, so everything is accepted!
Add a noop inline to check type, and fix up the two cases where we
used `const char *` instead of `char *`.

1. Allow 'any' as an option to zeroconf-selective.py plugin so we can use
it in line_graph where we don't know ids yet.
2. Use modern helpers like line_graph and remove debugging statement.
3. Don't use listchannels(): it's true that it shows local channels as well,
but that's a quirk I'd like to remove.
4. Make flake8 happy.
5. Rename to be more specific now it's a more narrow test.
I manually tested that the test still failed with the fixes removed, too,
so it is still the same test!

Otherwise what the hook sees is actually a lie, and if it sets it
we might override it.
The side effect is that we add an explicit "forward_to" field, and
allow hooks to override it. This lets a *hook* control channel
choice explicitly.
Changelod-Added: Plugins: `htlc_accepted_hook` return can specify what channel to forward htlc to.

We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
interface, where "XXXsat".

Fire off a snapshot of current account balances (node wallet + every
'active' channel) after we've caught up to the chain tip for the *first*
time (in other words, on start).
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.
