5d5741e681 libplugin: correctly wrap notifications we send in the notification name.
All the core notifications changed over to wrapping the notification
fields in an object with the name of the notification, but notifications
from plugins were missed.

Changelog-Added: Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notifications now have objects of the same name containing the expected fields.
Changelog-Deprecated: Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notification fields outside the same-named object.

16819f345d lightningd: make notifications from plugins just like native ones.
Rather than forcing them to wrap their parameters in a "payload"
sub-object, copy in params directly.  We include the "origin" field
one level up, if they care.

The next patch restores compatibility for the one place we currently use
them, which is the pay plugin.

fc5edea999 pyln-client: adapt for modern plugin notifications.
For older lightningd, we copy field into the raw dict, for newer we recreate the old
"payload" member.

We do fix up the custom_notification test which set params to a string instead of a dict:
that's just weird!

We also change the hacky parsing to proper dict extraction.

dbbb113123 tests: Add tests for extra_tlvs in hook
Adds some testcases for custom tlvs, set by a htlc_accepted_hook. We
check that the custom tlvs replace the update_add_htlc_tlvs and get
forwarded to the peer. We also check that a malformed tlv will result in
a **BROKEN** behaviour.

f442bd5012 fix: flake8 lint rules
Remove unnecessary global declarations across multiple test files. 
This change improves code quality by eliminating redundant global 
statements for variables that are already accessible in their 
respective scopes. Add proper type annotation for fees_from_status 
in test_closing.py and import the required typing modules. These 
changes maintain the same functionality while making the code cleaner 
and more compliant with Python best practices.

879d1191e8 splice: Bulk channel stfu and abort RPC
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

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.

75362d21c5 channeld_fakenet: fake channeld to simulate network given a gossmap_store.
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.

0e99f2e718 bkpr: add two custom notifications that we listen for
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.

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!
