Also report tx and txid, and whether we closed unilaterally or
bilaterally, if we could close the channel.
Also make a manpage.

We had an intermittant test failure, where the fee we negotiated was
further from our ideal than the final commitment transaction. It worked
fine if the other side sent the mutual close first, but not if we sent
our unilateral close first.

Really, if we're prepared to negotiate it, we should be prepared to
accept it ourselves. Simply take the cheapest tx which is above our
minimum.

The only use for these was to compute their txids so we could notify depth
in case of reorgs.

We are slowly hollowing out the in-memory blockchain representation to make

All of the callback functions were only using the tx to generate the txid again,
so we just pass that in directly and save passing the tx itself.
This is a simplification to move to the DB backed depth callbacks. It'd be
rather wasteful to read the rawtx and deserialize just to serialize right away
again to find the txid, when we already searched the DB for exactly that txid.

This will later allow us to determine the transaction confirmation count, and
recover transactions for rebroadcasts.

Internally both payment and routing use 64-bit, but the interface
between them used 32-bit.
Since both components already support 64-bit we should use that.
In the short_channel_id check we were copying the entire result into the next
bitcoin-cli call, including the newline character.

Creating the pid-file before daemonizing results in the pid-file containing the

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.

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.

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']}]}]

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.
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.

If we only remember the actions that added channels then we'd restore them when
re-reading the gossip_store, so put a tombstone in there to remember to delete
it. These will be cleared upon re-writing the store since the announcements wont
be written anymore.

This is necessary since we have onchaind tell us about the
