The `json_tok_percentage` parser is used for the `fuzzpercent` in `getroute` and
`maxfeepercent` in `pay`. In both cases it seems reasonable to allow values
larger than 100%. This has bitten users in the past when they transferred single
satoshis to things like satoshis.place over a route longer than 2 hops.
With the previous patch, we could still get stuck behind a low-prio
request. Generalize it into separate queues, and allow more than one
request in parallel.
Worth noting that the test time for `VALGRIND=0 pytest -vx tests/ -n 10`
doesn't change measurably.

fiatjaf has a cheap VPS, connecting remotely to his home bitcoind node.
fiatjaf's latency on bitcoin-cli getblock is between 10 and 37 seconds.
fiatjaf's c-lightning node is getting one block per hour.
fiatjaf is sad.
We single-file our bitcoind requests, because bitcoind has a limited
thread pool and it *fails* rather than queueing if you upset it. We
probably be fine using separate queues for each command type, but simply
allowing some requests to cut in line should prove my theory that we're
getting stuck behind gossip verification requests.
fiatjaf now gets one block per 2 minutes.
fiatjaf is less sad.

This is a simple reverse proxy that `bitcoin-cli` can talk to when invoked by
`lightningd`. It allows us to trace `bitcoin-cli` calls, and intercept calls to
mock the replies, better than the current bash-script based method.
Everything depends on common headers etc, and the HSM_CLIENT_HEADERS was removed
quite a while ago.

We would never complete further ping commands if we had < responses
than pings. Oops.

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.
