The ability to stfu channels in bulk is required to do complex multi channel operations. When stfu’ing in this manner, the available funds at the moment of stfu is returned to the user.
In order to cancel the stfu we also add a bulk tx_abort command.
Changelog-Added: `stfu_channels` and `abort_channels` are added for bulk multi-channel splice commands. These allow the user to pause (and resume) multiple channels in place.
Without knowing what method was called, we can't have useful general logging
methods, so go through the pain of adding "const char *method" everywhere,
and add:
1. ignore_and_complete - we're done when jsonrpc returned
2. log_broken_and_complete - we're done, but emit BROKEN log.
3. plugin_broken_cb - if this happens, fail the plugin.

When we used to allow cmd to be NULL, we had to hand the plugin
everywhere. We no longer do.
1. Various jsonrpc_ functions no longer need the plugin arg.
2. send_outreq no longer needs a plugin arg.
3. The init function takes a command, not a plugin.
4. Remove command_deprecated_in_nocmd_ok.

I started getting "WIRE_TEMPORARY_CHANNEL_FAILURE: Too many HTLCs" after
two hundred xpay attempts.
This was nice (it found some bugs in injectpaymentonion's handling of
local errors, and in xpay's reporting), but shouldn't happen.

Start with a random capacity (linear prob), and remember in-progess
payments so we can simulate them using capacity properly.

Note the impedence mismatch between sendpay and getroutes: we have to shift
amounts and delays by 1.

Our gossmap_store uncompresser generates nodeids with well-known
privkeys, so we can decrypt and respond to HTLCs sent to such nodes.
By replacing channeld with a fake, we can connect a node to another
node, but then once the channel is established, allow payments to be
sent into the generated network, and respond appropriately.
This minimal version handles MPP timeouts, but doesn't insert any
delays or runtime capacity for channels.

Changelog-None: Testing only
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)
