We reserve inputs when we're going to send a transaction, but we don't
unreserve them if we crash. This is most graphically demonstrated by
the txprepare case, which makes it easier to trigger.
Instead, we should query bitcoind to see whether the tx made it out or
not, as we would do manually with dev-rescan-outputs.

We now have a test blockchain for MCP which has the correct channels,
so this is not needed.
Also fix a benchmark script bug where 'mv "$DIR"/log
"$DIR"/log.old.$$' would fail if you log didn't exist from a previous run.

I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

This will make the logger write 4 newlines to re-attached logfiles.
The newlines wont appear on logfiles that are just created.
Additionally the server prints 50 '-' dashes before printing his
startup message, which also help increase readability on logfile.
This was inspired by the way Bitcoin Core handles logfiles.
Next patch will call commands to get usage inside jsonrpc_new(): to do
this it will need access to ld->jsonrpc, so we can't use the current
pattern.

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.

json_escaped.[ch], param.[ch] and jsonrpc_errors.h move from lightningd/
to common/. Tests moved too.
We add a new 'common/json_tok.[ch]' for the common parameter parsing
routines which a plugin might want, taking them out of
lightningd/json.c (which now only contains the lightningd-specific
ones).
The rest is mainly fixing up includes.

Note that this changes the order of arguments to pipecmd to match the
documentation, so we fix all the callers!
Also make configure re-run when configurator changes.

This currently just invokes GDB, but we could generalize it (though
pdb doesn't allow attaching to a running process, other python
debuggers seem to).

This tells the plugin both the `lightning-dir` as well as the
`rpc-filename` to use to talk to `lightningd`. Prior to this they'd
had to guess.

This is needed in order to be able to add methods while initializing
the plugins, but before actually moving to the config dir and starting
to listen.

This is the final step to get the plugins working. After parsing the
early options (including `--plugin`), then starting and asking the
plugins for options, and finally reading in the options we just
registered, we just need to assemble the options and send them over.

Also includes some sanity checks for the results returned by the
plugin, such as ensuring that the ID is as expected and that we have
either an error or a real result.
The idea is that `plugin` is an early arg that is parsed (from command
line or the config file). We can then start the plugins and have them
tell us about the options they'd like to add to the mix, before we
actually parse them.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

We want to try it before --daemon, in case we error, but we don't know
the pid yet, so we split into 'lock' and 'write'.

If we run two daemons on the same directory we'd be getting the failure from
trying to listen to the same file before we'd hit the pid-file error, which was
causing confusion.
Documentation changes:
1. Lots of extra detail suggested by @renepickhardt.
2. typo fixes from @practicalswift.
3. A section on 'const' usage.

Code changes:
1. Expose daemon_poll() so lightningd can call it directly, which avoids us
having store a global and document it.
2. Remove the (undocumented, unused, forgotten) --rpc-file="" option to disable
JSON RPC.
3. Move the ickiness of finding the executable path into subd.c, so it doesn't
distract from lightningd.c overview.
