* 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?

Without this the RPC will fail to continue buffering if the response does not
fit in the first read, and if we don't switch over to the non-compat
mode. This was introduced by our mitigation of the UTF-8 misalignment, but I
missed this path.

These weren't checked by CI yet, and they are really short so I just added

This indicates that the method or hook will accepts a request
parameter, and will use that to return the result or raise an
exception instead of returning the return value. This allows the hook
or method to stash the incomplete request or pass it around, without
blocking the JSON-RPC interface.

This isn't a problem for now since we don't support multithreading,
and only allow synchronous calls, but eventually this'll become
important.

We well need this in the next commit to be able to return from an
asynchronous call. We also guard stdout access with a reentrant lock
since we are no longer guaranteed that all communication happens on
the same thread.

Sending around unnamed tuples is bound to cause some issues sooner or
later, so we just create a quick class that holds all the information
about a plugin method.

Little point having users handle the postfixes manually, this
translates them, and also allows Millisatoshi to be used wherever an
'int' would be previously.
There are also helpers to create the formatting in a way c-lightning's
JSONRPC will accept.
All standard arithmetic operations with integers work.

We read a JSON message from the buffer, after converting it from raw bytes to
UTF-8, and returning the remainder of the byte array back to the
caller. However the return value of `raw_decode` refers to symbols in the
UTF-8 decoded string, not the raw bytes underlying byte-array, which means
that if we have multi-byte encoded UTF-8 symbols in the byte-array we end up
with a misaligned offset and will return part of the message as
remainder. This would then end up being interpreted as the result of the next
call.
This could not be exploited currently since we use a socket only for a single
JSON-RPC call and will close the connection afterwards, but since we want to
eventually recycle connections for multiple calls, this could have been very
dangerous.

The next patch wants to decorate the methods with a compulsory
'usage' option, which doesn't make sense for init. So I wanted
to change the init to its own decoration.

This was failing the docker hub builds, since the git-config retains
an absolute path to the worktree location when cloning. Copying it
over from the host system means that this path now points to a
non-existent location, which then interfered with the submodule
initialization.
This fixes it by not using the copy directly, but rather it creates a
clean clone from the copied location, including a submodule init.

Instead of creating a new map I opted to re-use the Plugin.methods
map, since the semantics are really similar and we don't allow
duplicates. The only difference is in how they are announced to
lightningd, so we use an enum to differentiate rpcmethods from hooks,
since only the former will get added to the JSON-RPC dispatch table in
lightningd.

After this code change people can use `plugin.rpc` from anywhere in
their plugin code this is much nicer than going this way:
```
@plugin.method("init")
def init(options, configuration, plugin):
global rpc
basedir = plugin.lightning_dir
rpc_filename = plugin.rpc_filename
path = os.path.join(basedir, rpc_filename)
rpc = LightningRpc(path)
```
or similarly that way:
```
@plugin.method("init")
def init(options, configuration, plugin):
global rpc
basedir = configuration['lightning-dir']
rpc_filename = configuration['rpc-file']
path = os.path.join(basedir, rpc_filename)
rpc = LightningRpc(path)
```
Also the imports have been sorted alphabetically

If the `request` or `plugin` parameter that are injected by the
framework where before or inbetween positional arguments we'd be
injecting them incorrectly, i.e., we'd be providing them both as
`args` (and mismapping another argument) as well as `kwargs`.
This is a better way to map arguments, which takes advantage of the
fact that JSON-RPC calls are either all positional or named arguments.
I also included a test for various scenarios, that hopefull cover the
most common cases.
