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.
The first argument of 'ping' was documented as 'peerid', however
internally it is expected to be just 'id'.
To avoid breaking the API, opt to fix the documentation.
Installing pytest through pip3 (at least sometimes) doesn't create a script.
This means calling `which` won't work.
Changed configure so that it can also test if the module is present by calling python/python3.
Change the error message for when pytest can't be found, so that it's clear to the user `configure` must be ran again after installing pytest.
It's an array: we were only saving the single element; if there was more than
one changed HTLC we'd get a bad signature!
The report in #1907 is probably caused by the other side re-requesting
something we considered already finalized; to avoid this particular error,
we should set the field to NULL if there's no last_sent_commit.
I'm increasingly of the opinion we want to just save all the update
packets to the db and blast them out, instead of doing this
second-guessing dance.
Fixes: #1907

If we receive a channel_announce but not a channel_update, we store the announce
but don't put it in the broadcast map.
When we delete a channel, we check if the node_announcement broadcast
now preceeds all channel_announcements, and if so, we move it to the
end of the map. However, with a channel_announcement at index '0',
this test fails.
This is at least one potential cause of the node map getting out of order.

These happen after we compact the store; every log I've seen of a
restart on a real node has a message about truncating the store,
because node_announcements predate channel_announcements.
I extracted one such case from testnet, and reduced it to test here.

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.

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.

This could have been a local static but its used by the run-param test,
so putting it in json.c made things easier.
