lightningd now uses a WHOIS query on itself to learn its external IP
address and announces that on the channel with the NODE message. It also
tracks other nodes in the routing table.
Refactored the signature verification to reuse it for both CHAN and NODE
messages.
We *should* be in a state which accepts it (could happen with reorg),
and there's no reason to test for greater than depth since we must process
blocks in order.

Currently we get the odd message "Own anchor has insufficient funds".

This is expected: it happens when node3 is restarting. Redirect

Added channel announcement serialization and parsing, as well as the
entrypoints for the IRC peer discovery. Announcements are signed by the
sending endpoint and signatures are verified before adding the channels
to the local view of the topology. We do not yet verify the existence of
the anchor transaction.
The IRC library can login and keep its connection alive by replying to
PING messages. It also exposes a callback that handles PRIVMSG commands
and can inject messages from outside, e.g., based on a timer or a
lightning event.
It's not in a transaction in one caller, so wrap that.
This removes some more error handling code.

Rename the structs to match (and remove dev-echo).
This makes it clear that they're not the normal API.

We need some ordering to deliver them to the JSON "waitinvoice" command;
we use a counter where 0 means "unpaid".
We keep two lists now, one for unpaid and one for paid invoices.

We need some way to reflect the tradeoff between the possible delay if
a payment gets stuck, and the fees charged by nodes. This adds a risk
factor which reflects the probability that a node goes down, and the
cost associated with losing access to our funds for a given time.

I had some nonsensical columns, eg "bool ours", but sqlite3 pretty much
ignores them. Use macros so mistakes are harder to make.

This is important when we put payments in the database: they need to be
updated atomically as the HTLC is.

We had enum channel_side (OURS, THEIRS) for which end of a channel we
had, and htlc_side (LOCAL, REMOTE) for who proposed the HTLC.
Combine these both into simply "enum side".

In particular, make sure B can just afford it, then have the A add a
HTLC which means B can no longer afford the fees, and A should cover
it.
We do this by modifying the previous overlapping-fail test, but we
need to have B offer it the htlc before A does: racy in the normal
autocommit case. So we do a manual commit here, always.

When they propose an HTLC to us, they need to be able to cover both it,
and the associated fees. When it gets acked and applied to them, however,
they may no longer be able to afford the fees; this is OK and expected.
So add a flag to say whether they can dig into fees or not: without
this patch the code calls fatal() on the next patch which tests it.
