Avoids guessing what the timeout should be, use a file trigger. This
is more optimal, and should reduce a flake in test_sql under valgrind.

This changes various tests in minor ways:
1. The "l2" secret key in tests/plugins/channeld_fakenet.c is updated.
2. The decompressed gossip data node id needs changing.
3. The coinmoves order changes in bookkeeper for anchors.
4. Various harcoded gossip constants change.
5. Some hardcoded makesecret results change.
6. zeroconf tests which hardcoded node ids change.
7. Arbitrary rune strings change.
8. A log message which uses node ids changes.

If we add a new hook, not at the end, while hooks are getting called,
then iteration could be messed up (e.g. calling a plugin twice, or
skipping one).
The simplest thing is to defer updates until nobody is calling the
hook. In theory this could livelock, in practice it won't.

This includes a mocked lsps2 service plugin, tests and some changes on
the client side. The client now can accept mpp payments for a
jit-channel opening from a connected LSP.
Changelog-Added: Lsps2 `fixed-invoice-mpp` mode for the lsps2 client
Signed-off-by: Peter Neuroth <pet.v.ne@gmail.com>
Adds the service side (LSP) for a simple no-mpp trusted jit channel
opening. This is only an intermediate step, we are going to add support
for multiple htlcs.
This is experimental and can drain on-chain fees from the LSP if used in
public.

This commit adds the lsps2_get_info call defined by BLIP052. It also
adds a test policy plugin that the LSP service plugin uses to fetch the
actual fee menu from to separate the concerns of providing a spec
compliant implementation of an LSP and making business decisions about
fee prices.

This commit introduces a new field `invoice_msat` to the htlc_accepted
hook. If this field is specified it will replace the amount of the
invoice that belongs to the payment_hash of the HTLC on internal checks.
This is useful in scenarios where we actually expect a smaller amount
than initially specified in an invoice.
Changelog-Changed: Plugins: `htlc_accepted` hook can now override the
expected total amount of the invoice that belongs to the HTLC.

Each header should only include the other headers it needs to compile;
`devtools/reduce-includes.sh */*.h` does this. The C files then need
additional includes if they don't compile.
And remove the entirely useless wire/onion_wire.h, which only serves to include wire/onion_wiregen.h.

1. $(JSMN_OBJS) is not set anywhere.
2. You don't need to depend on CCAN_HEADERS, COMMON_HEADERS or JSMN_HEADERS: the top level Makefile has all object depedning on it.
3. Similarly, CCAN_OBJS.
4. Every object file should be rebuilt if its Makefile changes.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This means we don't have to manually choose what to link against,
which is much of the complexity of our Makefiles: the compiler will
automatically use any object files it needs to link.
We already do this for ccan as libccan.a, now we have libcommon.a.
We don't link against it for *everything*, as some tests require their own
versions.
Notes:
1. I get rid of the weird plugins/test/Makefile2 (accidental commit?)
2. Many tests change due to update-mocks.
3. In some places I added the missing dependency on the Makefile itself, though most are in the next
patch.

After much thought and mis-steps, I chose a simple solution: open another fd
for sync comms. It's almost impossible to know what state the async one is in.
jsonrpc_request_sync() is enhanced to return a valid tal object, as the current
behaviour of returning a pointer to inside an array was surprising.
Changelog-Changed: libplugin: you can now call the synchronous API functions at any time (not just in the init callback).

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.

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.

Changelog-Deprecated: pyln-client: plugin custom notifications origins and payload (use parameters directly)
For older lightningd, we copy field into the raw dict, for newer we recreate the old

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.

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.
It was already disabled by Dusty due to a number conflict with splicing, and
the proposal probably needs updating to use quiescence now that is merged.

Keep a proper cache of all possible ones. I think this may be the
timeout problem: according to the logs, channeld_fakenet stops responding
and thus HTLCs eventually time out.

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.
