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.

We were having a few issues with malformed data in the past, so this time we
really check that stuff.

And clean up some dev ones which actually happen (mainly by calling
channel_fail_permanent which logs UNUSUAL, rather than
channel_internal_error which logs BROKEN).

1. Create a plugin: ./lightning/tests/plugins/pretend_badlog.py
This plugin subscribes 'warning' notification and log the payload of
'warning';
2. Add a new test: tests/test_plugin.py::test_warning_notification
This test runs the plugin-pretend_badlog.py and check if 'warning'
notification can be normal triggered and subscribed.
Plugins don't do it right anyway, and we're about to remove it from
lightningd. Produces same format as json_pp.

1. We need to read in as a byte string, then decode into utf8 once we
have a marker. Otherwise we seem to mangle it horribly, and we
might have a bad utf8 string anyway.
2. We need to suppress the JSON \u escapes on output.

We should be able to pass UTF-8 strings to and from plugins without
python turning them into JSON-\u escapes.

Rather than using LightningJSONDecoder's implicit "field name and
value ends in msat, try converting to Millisatoshi", we do it to
parameters using type annotations.
If you had a parameter which was an array or dict itself, we don't
delve into that, but that's probably OK.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We don't, but we should, like we do for normal RPC. However, I chose
to use function annotations, rather than names-ending-in-'msat'
because it's more Pythony.

This is the same deprecation, but one level up. For the moment, we
still support invoices with a `h` field (where description will be
necessary) but that will be removed once this option is removed.
Note that I just changed pylightning without backwards compatibility,
since the field was unlikely to be used, but we could do something
more complex here?

Internally libplugin turns ' into ", which causes these messages to produce
bad JSON.
The real fix is to remove the '->" convenience substitution and port the
JSON creation APIs into common/ from lightningd/

I wrote this sync first, then rewrote async, then developed libplugin.
But committing all that just wastes reviewer time, so I present it as
if it was always asnc and using the library helper.
Currently the command it registers is 'pay2', but when it's complete
we'll remove the internal 'pay' and rename it. This does a single
'getroute/sendpay' call. No retries, no options.
Shockingly, this by itself is almost sufficient to pass our current test
suite with `pay`->`pay2`.

Since we are planning to release a bug fix release, and the plugin
subsystem is not yet complete, it is better to make plugin support
opt-in while we continue testing.

Both of these plugins will fail in interesting ways, and we should
still handle them correctly.
