Repeated crashes could result in the `last_processed_block` variable being
pushed further and further into the past (in some cases going as far back as
scanning blocks from 2012...). This is a stop-gap solution that just lower
bounds the value to what is the first possible block we might be interested in
LN, until we have the 0-rescan fix I'm working on.

Just a small cleanup of the indentation code, so we don't have to reformat all
the issue reports to become readable. This is much closer to what `jq` or
`json_pp` spit out and doesn't have those infinitely long lines.

Creating the pid-file before daemonizing results in the pid-file containing the
pid of the process that started the daemon, but is now dead.

We can have more than one; eg we might offer both bech32 and a p2sh
address, and in future we might offer v1 segwit, etc.

In particular, this gets some MacOS fixes from #1327.
It also includes a major intmap update which fixes corner cases in traversals,
and requires ccan/bitops.

There are two very hard problems in software engineering:
1. Off-by-one errors
In this case we were rolling back further than needed and we were starting the
catchup one block further than expected.

This allows us to have some default options that can then be overridden easily
on a per-test basis.

I saw a failure in test_funding_fail():
assert l2.rpc.listpeers()['peers'][0]['connected']
This can happen if l2 hasn't yet handed back to gossipd. Turns out
we didn't mark uncommitted channels as connected:
[{'id': '03afa3c78bb39217feb8aac308852e6383d59409839c2b91955b2d992421f4a41e', 'connected': False, 'channels': [{'state': 'OPENINGD', 'owner': 'lightning_openingd', 'funder': 'REMOTE', 'status': ['Incoming channel: accepted, now waiting for them to create funding tx']}]}]

'negotiation_failed' is currently just a useless wrapper around
peer_failed (a vestige from when peer_failed would close the
connection). Change it to send different local and remote messages,
and use it wherever we dislike their parameters: stick with
peer_failed if we dislike our own parameters.

This is probably covered by our "channel capacity" heuristic which
requires the channel be significant, but best to be explicit and sure.

So we know how much counterparty could theoretically steal from us
(msatoshi_to_us - msatoshi_to_us_min) and how much we could
theoretically steal from counterparty (msatoshi_to_us_max -
msatoshi_to_us).
For more piloting goodness.
We previously tried to use the commitment tx to create an initial
feerate range, then refine it as we look at each HTLC tx. This was
wrong, because the commitment tx can underpay fees (if it can't afford
it), and our estimate of the maximum possible feerate would be too low.
Now, we only have two fees we need to figure out: HTLC timeout txs and
HTLC success txs, so simply grind them on first use.

These are basic instructions that lead to the build process completing without error (after a known error occurs and is rectified). For now, the final results are untested.
In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.

I didn't convert all tests: they can still use a standalone context.
It's just marginally more efficient to share the libwally one for all
our daemons which link against it anyway.
