"multi" means that specifying a parameter twice will append, not override.
Multi args are always given as a JSON array, even if only one.

Changelog-Added: Plugins: new "multi" field allows an option to be specified multiple times.
This only adds a test that currently makes sure its not possible
to init a Millisatoshi by a floating number.
Discussion:
As @gallizoltan points out, initialization with a float should be possible:

> Millisatoshi(5) / 2 currently works, and removes the half msat.
> So, I think Millisatoshi(5 / 2) should be the same.
Before this patch this fails: `Millisatoshi(42) / Millisatoshi(2)`
This is an operation that should return the ratio between the two
operands as a float number. Same goes for __floordiv__ operator `//`.

We promised to deprecate the old "destination satoshi feerate utxos"
variant some time on mid-2020 so let's do just that. `txprepare`
doesn't parse it either anymore.
Changelog-Changed: pyln: `txprepare` no longer supports the deprecated `destination satoshi feerate utxos` call format.
Logs may contain non-ASCII and non-UTF8 symbols, which crashes the
tailer. It's better to replace them with a glyph representing
undecodeable symbols instead, and handle the issue further up the
call-chain.
We rely on it when logging, but didn't set it in the class, rather we
did in the sub-classes. This proved to be rather annoying to search
since it'd just fail silently and not log any output.
This will change the current hardwired PostgreSQL binary lookup mechanism to
utilizing the `pg_config --bindir` utility that should work better for most
distributions. The old method caused issues at least on Archlinux.
Changelog-None
We also sanity check that response id matches our request.

Changelog-Added: pyln: pyln.client handles and can send progress notifications.
- Adds bitarray filling so mesages of any length can be encoded, instead of forcing the encoding to be of messages with length multiple of 5.
- Adds checks for encoding / decoding and raises expections if the inputs are not as expected.
- Flags functions that are supposed to be internal as "private".
My bad, i comitted them as part of the LSAN suppressions while this data
race could have and had been fixed.

`openchannel_signed` and `openchannel_update` which allow a user to
continue a openchannel or kick off the completion of a openchannel.
`openchannel_update` should be called until it returns with
`commitments_secured`.
Finally, extends the 'close_to' functionality up to the flagship 'open a
channel' command.
Changelog-Added: JSON-API `fundchannel` now accepts an optional 'close_to' param, a bitcoin address that the channel funding should be sent to on close. Requires `opt_upfront_shutdownscript`
We had a couple of instances where a plugin would be killed by `lightningd`
because we were returning a result of an exception twice, and it was hard to
trace down the logic error in the user plugin that caused that. This patch
adds a traceback the first time we return a result/exception, and raise an
exception with a stacktrace of the first termination when a second one comes
in.
This can still terminate the plugin, but the programmer gets a clear
indication where the result was set, and can potentially even recover from it.
Changelog-Added: pyln: Plugin method and hook requests prevent the plugin developer from accidentally setting the result multiple times, and will raise an exception detailing where the result was first set.
It is often pretty usefuk to use the builtin logging module to debug things,
including libraries that a plugin may use. This adds a simple
`PluginLogHandler` that maps the python logging levels to the `lightningd`
logging levels, and formats the record in a way that it doesn't clutter up the
`lightningd` logs (no duplicate timestamps and levels).
This allow us to tweak the log level that is reported to `lightningd` simply
using the following
```python3
import logging
logging.basicConfig(level=logging.DEBUG)
```
Notice that in order for the logs to be displayed on the terminal or the
logfile, both the logging level in the plugin _and_ the `--log-level`
`lightningd` is running need to be adjusted (the python logging level only
controls which messages get forwarded to `lightningd`, it does not have the
power to overrule `lightningd` about what to actually display).
I chose `logging.INFO` as the default, since libraries have a tendency to spew
out everything in `logging.DEBUG` mode
Changelog-Added: pyln: Plugins have been integrated with the `logging` module for easier debugging and error reporting.
Since we start a new instance of postgres for each test we may end up swamped
and the startup can take a bit longer. So let's loop until we get a success.
It was really flaky, especially under `test_mpp_interference_2`, most likely
due to multiple calls to `fund_channel`. This commit looks for the specific
txids in the `listfunds` output and the `getrawmempool` output, avoiding
strange artifacts from multiple calls.
For performance reasons we were starting one for each session, which caused
the same postgres DB to be re-used for multiple tests (all test run in the
same worker process), but this could lead to interactions if there is a
timeout or a test happens to touch the `db_provider`. It turns out that we
were only saving about 15 seconds on a 1250 second run anyway, which is a
small cost for increased test isolation.
