Add an RPC method (not working at the moment) called
`fundchannel_continue` that takes as its parameters a
node_id and a txid for a transaction (that ostensibly has an output
for a channel)
The next commit breaks it: `if b' }\n' not in buff:` is always true since
we're about to clean up our JSON so there won't be a space. I could have
hacked the space in our JSON, but 6 months is long enough anyway.

Tries to return the approxmost posible string of a Millisatoshi amount using
various unit representations. The function will round to an effective
number of digits. Default: 3.
```
>>> Millisatoshi("100000sat").to_approx_str()
'0.001btc'
>>> Millisatoshi("100msat").to_approx_str()
'0.1sat'
>>> Millisatoshi("10000000sat").to_approx_str()
'0.1btc'
```
We had a bit of a hand-woven mess in there, trying to inject the extra
arguments in the correct places. We now instead treat positional and keyword
calls separately and can go back to using the builtin argument binding again.

The old codes if % 1000 statement logic was simply inverted
and produced the opposite output of the intention behin it.
Before Fix:
- Millisatoshi('42sat').to_btc_str() => 0.00000042000btc
- Millisatoshi('42001msat').to_btc_str() => 0.00000042btc
After Fix:
- Millisatoshi('42sat').to_btc_str() => 0.00000042btc
- Millisatoshi('42001msat').to_btc_str() => 0.00000042001btc
Currently, when a multiplication operator is invoked that
does not result in an even integer result but a floating result,
the pylightning code will raise an exception:
Millisatoshi must be string with msat/sat/btc suffix or int
This is because the internal float result will be used as
contructor argument like this: return Millisatoshi(10000.5)
This happens especially on fee calculations where small uneven amounts
are calculated.
Millisatoshi's inner representation expected to be an int, otherwise unwanted exceptions could occur
The following example raises: TypeError: __int__ returned non-int (type decimal.Decimal)
from lightning import Millisatoshi
one_sat = Millisatoshi("1sat")
two_sats = one_sat * 2
make it easier to fire up a local test environment to try out
c-lightning.
requires bitcoind to be installed. to use, you have to run it
via `source contrib/startup_regtest.sh`, so that the aliases
are set correctly.
* Improved plugin install in docker
- All files generated by 'make install' are copied
- Fixes issues with incomplete installation.
- Example: New executables created by build but are missing in docker.
With the preceeding UTF-8 fix, I'd like to detect UTF-8 support. But
AFAICT Python doesn't have a standard way of doing version exposure.
So I added __version__, but now we need to make sure it matches. I
used the hackiest possible method.
[ Christian Decker fixed version to be sane, so previous comment no longer
applies! --RR ]

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.

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.

I originally converted input JSON naively into Millisatoshi, and the
result was a strange failure in Millisatoshi.__eq__.
It seems this is because inspect._empty.__eq__(Millisatoshi) raises
NotImplemented, and so it tries Millisatoshi.__eq__(inspect._empty)
which doesn't like it.
'is' is the correct test here, AFAICT, and doesn't suffer from these
problems.

Some JSON functions want a *class*, not just a hook, so provide one.
To make it clear that we want an encoding *class* and a decoding *object*,
rename the UnixDomainSocketRpc encode parameter to encode_cls.

If we can't marshall an object into JSON, the exception causes a deadlock
and we don't get any results.
Instead of deadlocking, our failure now is:
lightning.lightning.RpcError: RPC call failed: method: echo, payload: {'msat': 17msat}, error: Error while processing echo: TypeError("Object of type 'Millisatoshi' is not JSON serializable",)

I tried annotating the plugin-millisatoshis.py plugin, and it failed like so:
plugin-millisatoshis.py Killing plugin: "getmanifest" result is not an object: {"jsonrpc": "2.0", "id": 1, "error": "Error while processing getmanifest: ValueError(\'Function has keyword-only parameters or annotations, use getfullargspec() API which can support them\',)"}'
So, let's do that!

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?
