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

Changelog-Removed: Relative plugin paths are not relative to startup (deprecated v0.7.2.1)
Changelog-Removed: Dummy fields in listforwards (deprecated v0.7.2.1)
Changelog-Changed: plugin: `notify_sendpay_success` and `notify_sendpay_failure` are now always called, even if there is no command waiting on the result.
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.
Thanks to @t-bast, who made this possible by interop testing with Eclair!
Changelog-Added: Protocol: can now send and receive TLV-style onion messages.
Changelog-Added: Protocol: can now send and receive BOLT11 payment_secrets.
Changelog-Added: Protocol: can now receive basic multi-part payments.
Changelog-Added: RPC: low-level commands sendpay and waitsendpay can now be used to manually send multi-part payments.

In particular:
1. It must redirect to an existing command.
2. It must contain method, params and id.
And update the docs to show the id, which is vital.

Changelog-changed: .lightningd plugins and files moved into <network>/ subdir
Changelog-changed: WARNING: If you don't have a config file, you now may need to specify the network to lightning-cli

So far we've only handled legacy payloads, which meant we could drop the realm
byte since it was always 0x00. Once we start handling TLV payloads the first
byte, i.e., the former realm byte, is important since it gives us the length
of the payload. This is a breaking change, however I don't think there's
anyone using the `raw_payload` as of yet.
Changelog-Changed: JSON-RPC: the `raw_payload` now includes the first byte, i.e., the realm byte, of the payload as well. This allows correct decoding of a TLV payload in the plugins.
Spaces just make life a little harder for everyone.
(Plus, fix documentation: it's 'jsonrpc' not 'json' subsystem).

1. Printed form is always "[<nodeid>-]<prefix>: <string>"
2. "jcon fd %i" becomes "jsonrpc #%i".
3. "jsonrpc" log is only used once, and is removed.
4. "database" log prefix is use for db accesses.
5. "lightningd(%i)" becomes simply "lightningd" without the pid.
6. The "lightningd_" prefix is stripped from subd log prefixes, and pid removed.

Changelog-changed: Logging: formatting made uniform: [NODEID-]SUBSYSTEM: MESSAGE
Changelog-removed: `lightning_` prefixes removed from subdaemon names, including in listpeers `owner` field.
A log can have a default node_id, which can be overridden on a per-entry
basis. This changes the format of logging, so some tests need rework.

Changelog-changed: JSON API: `htlc_accepted` hook has `type` (currently `legacy` or `tlv`) and other fields directly inside `onion`.
Changelog-deprecated: JSON API: `htlc_accepted` hook `per_hop_v0` object deprecated, as is `short_channel_id` for the final hop.
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).
These are used to do one-time initializations and wait for pending statements
before closing.

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.

@renepickhardt has a shell script we broke. While we still produce
perfectly valid JSON, we should not gratuitously change tool output.
Plus, I prefer the missing space before the ':'.

This is a followup to #2892. Since we now attempt to lock the PID file before
starting plugins we need to make sure that we actually use a unique lightning
directory for anything that attempts to call `--help`. If not we may be
conflicting with a `lightningd` that is running against that directory.
Notice that this still means that we will be unable to call `--help` on
`lightningd` if we have a running instance, but isolation in this case is
good, otherwise we'd be reading the default config anyway.

Note that we move adding the plugin to the plugins list to the end, otherwise
the hook from logging can examine the (uninitialized) plugin.
