This makes use of the payment modifier structure to just add the preimage to
the TLV payload for the last hop.
Changelog-Added: JSON-RPC: The `keysend` command allows sending to a node without requiring an invoice first.
There are various places where our tests failed with
--enable-expimental-features. And our plugin test overlapped an
existing feature.
We make our expected_feature functions more generic, and use them
everywhere.

Previously we were annotating every movement with the blockheight of
lightningd at notification time. Which is lossy in terms of info, and
won't be helpful for reorg reconciliation. Here we switch over to
logging chain moves iff they've been confirmed.
Next PR will fix this up for withdrawals, which are currently tagged
with a blockheight of zero, since we log on successful send.
We modify the slow_init() so it doesn't go too slowly for this test.
This demonstrates a crash, where we currently try to fail a command
multiple times.

This actually passes fine, but it's an interesting case to test.

Telling `lightningd` to pass a `-datadir` to `bitcoin-cli` so it doesn't go
snooping where it doesn't belong (i.e., the user's home directory and config).

As discussed with Christian, prepending the length to the payload returned
is awkward, but it's the only way to set a legacy payload. As this will
be soon deprecated, simplify the external API.

We now track all pending RPC passthrough calls, and terminate them with an
error if the plugin dies.
Changelog-Fixed: JSON-RPC: Pending RPC method calls are now terminated if the handling plugin exits prematurely.
Shows what features we use in various contexts, including those added
by plugins in getmanifest.

Changelog-Added: Plugin: `feature_set` object added to `init`
This adapts our fee estimations requests to the Bitcoin backend to the
new semantic, and batch the requests.
This makes our request for fees much simpler, and leaves some more
flexibility for a plugin to do something smart (it could still lie before
but now it's explicit, at least.) as we don't explicitly request
estimation for a specific mode and a target.
Changelog-Changed: We now batch the requests for fee estimation to our Bitcoin backend.
Changelog-Changed: We now get more fine-grained fee estimation from our Bitcoin backend.
We were nesting like the following:
```json
{"params": {
"rpc_command": {
"rpc_command": {
}
}
}
```
This is really excessive, so we unwrap once, and now have the following:
```json
{"params": {
"rpc_command": {
}
}
```
Still more wrapping than necessary (the method is repeated in the `params`
object), but it's getting closer.
Changelog-Deprecated: JSON-RPC: Removed double wrapping of `rpc_command` payload in `rpc_command` JSON field.

Make the `htlc_accepted` hook the first chained hook in our repertoire. The
plugins are called one after the other in order until we have no more plugins
or the HTLC was handled by one of the plugins. If no plugins handles the HTLC
we continue to handle it internally like always.
Handling in this case means the plugin returns either `{"result": "resolve",
...}` or `{"result": "fail", ...}`.
Changelog-Changed: plugin: Multiple plugins can now register for the htlc_accepted hook.
This completes the custommsg epic, finally we are back where we began all that
time ago (about 4 hours really...): in a plugin that implements some custom
logic.
We clone the test above, but this time we don't attach waiters (they'd be racy
anyway), and we wait for the notification to be called. This fails, but is
fixed in the next two commits.
Rounds out the application of `upfront_shutdown_script`, allowing
an accepting node to specify a close_to address.
Prior to this, only the opening node could specify one.
Changelog-Added: Plugins: Allow the 'accepter' to specify an upfront_shutdown_script for a channel via a `close_to` field in the openchannel hook result
This adapts the test to the new 'plugin' command: no more sleeping,
since we are synchronous !
This tests the timeout by increasing the 'slowinit' plugin sleep
duration at init reception.
This adds a broken plugin to make sure we won't crash because of a
misbehaving plugin (unmet dependency is the most common case).
This has a slight side-effect of removing the actual begin and commit
statements from the `db_write` hooks, but they are mostly redundant anyway (no
harm in grouping pre-init statements into one transaction, and we know that
each post-init call is supposed to be wrapped anyway).

We seem to be getting intermittant failures, but it's hard
to disgnose. Simplify it by moving all the test logic into
the test itself, and making the plugin dumber. This means we'll
see exactly what the differences are if it fails again.
