While we were unsetting the `payment->cmd` in case of a success to signal that
we should not return to the JSON-RPC command twice, we were not doing that in
the case of failures. This was causing multiple responses to a single incoming
command, and `lightningd` was correctly killing the plugin. This issue was
introduced through early returns (anything setting `payment->abort=true`) and
was caused in Rusty's case through an MPP timeout.

These are pulled from wallet/wallet.c, with the fix now that we grind sigs.
This reduces the fees we pay slightly, as you can see in the coinmoves changes.
I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

There is a race between `getroute` learning that our peer accepts TLVs and us
initiating the payment. Waiting for announcements ensures we always use TLVs,
matching our expectation in the test / plugin.
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.

This moves the notification for our coin spends from when it's
successfully submited to the mempool to when they're confirmed in a
block.
We also add an 'informational' notice tagged as `spend_track` which
can be used to track which transaction a wallet output was spent in.
The previous implementation was a bit lazy: in particular, since we didn't
remember the disabled plugins, we would load them on rescan.
Changelog-Changed: config: the `plugin-disable` option works even if specified before the plugin is found.
That's more convenient for most callers, which don't need a fmt.

This is what I expected from plugin_kill, and now all the callers do the
equivalent anywat, it's easy.

This means we now clean up options in startup plugins (that was only
done by dynamic code!), and now they both share the 60 second timeout
instead of 20 seconds for dynamic.
For the dynamic case though, it's 60 seconds to both complete
getmanifest and init, which seems fair.

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.

The new `keysend` plugin modifies the node features that we send to
peers. This commit breaks out the 'expected_features' we use for tests
to encompass this differentiation.
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`
a few things. one is that `is_in_log` returns a result rather than
enforcing a condition. so these lines all need asserts
two is that with the 'allow_deprecated_apis' option on, the python json
parser overwrites the now typed input with the later-added string
version, so the only option value present in the option key-value set is
the last, string one. the check for this has been updated to only verify
that the string version is included (i manually verified that both are
printed to the JSON message)
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 is the last venue we need to add custom featurebits to, so we also unmark
the test as xfail.
Changelog-Added: plugin: Plugins can now signal support for experimental protocol extensions by registering featurebits for `node_announcement`s, the connection handshake, and for invoices. For now this is limited to non-dynamic plugins only
As a separated commit because it was pre-existent (changelog + xfail test).
This also fix a logical problem in lightningd/plugin_control: we were
assuming a plugin started with 'plugin start' but which did not comport
a 'dynamic' entry in its manifest to be dynamic, though it should have
been treated as static.
Changelog-fixed: plugins: Dynamic C plugins can now be managed when lightningd is up
