Takes advantage of upfront-shutdown-script to permit users to
specify the close-to address for a channel at open, by adding
a `close_to` field to `fundchannel_start`.
Note that this only is in effect if `fundchannel_start` returns
with `close_to` set -- otherwise, peer doesn't
support `option_upfront_shutdown_script`.
Command format: close id [unilateraltimeout] [destination]
Close the channel with peer {id}, forcing a unilateral
close after {unilateraltimeout} seconds if non-zero, and
the to-local output will be sent to {destination}. If
{destination} isn't specified, the default is the address
of lightningd.
Also change the pylightning:
update the `close` API to support `destination` parameter
* Add compatibility with the new shortchannelid syntax with x as separator
* Add an error message in case the parse failed, instead of receveing an unrelated error from the bitcoin-cli
This is the first step to transition to a better organized python module
structure. Sadly we can't reuse the `pylightning` module as a namespace module
since having importable things in the top level of the namespace is not
allowed in any of the namespace variants [1], hence we just switch over to the
`pyln` namespace. The code the was under `lightning` will now be reachable
under `pyln.client` and we add the `pyln.proto` module for all the things that
are independent of talking to lightningd and can be used for protocol testing.

Allow a user to select the utxo set that will be added to a
transaction, via the `utxos` parameter. Optional.
Format for utxos should be of the form ["txid:vout","..."]

`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call. `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.
Timing out JSON calls is generally deprecated: that's the job of the
client. And the semantics of this are confusing, even to me! A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.
The transition code is awkward, but we'll manage for the three
releases until we can remove it.
The new defaults are to unilaterally close after 48 hours.

The helpme plugin is more comprensive, but this at least connects to a
few random nodes, and doesn't require python libraries in path or anything.
I selected the nodes from helpme.py, eliminating ones I couldn't reach.

We recently noticed that the way we unpack the call arguments for hooks and
notifications in pylightning breaks pretty quickly once you start changing the
hook and notification params. If you add params they will not get mapped
correctly causing the plugin to error out.
This can be fixed by adding a `VAR_KEYWORD` argument to the calbacks, i.e., by
adding a single `**kwargs` argument at the end of the signature. This commit
adds a check that such a catch-all argument exists, and emits a warning if it
doesn't.
It also fixes up the plugins that we ship ourselves.
