Make this always the first packet after auth. That means there's no
reliance on whether a node remembers an aborted connection.
It also gives us a place to put version bits.

This gives much better errors, and allows us to return the peer id.

Firstly, we need to update the staging fee amount when we queue a change.
Secondly we need to remove completed fee updates, otherwise we hit a
database constraint that peer & state are unique.

We were out by 1000, and also derived it from the previous, not current
state.

We store peers in the database for STATE_INIT, but they don't reconnect
properly. We should not forget STATE_INIT dropped peers, but use some
timeout mechanism if we can't reconnect to clean up.

Fix dff50c3a5f2224592d135ad9cc6c11be89e26def: if multiple blocks come between
polling, we'll get called once for the new tip.

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.

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.

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".

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.

We create a logging object when we connect, then carry it through. If
it comes from the database, we just use the peerid as the log prefix.

If we haven't received their closing signature yet, we might try to
send the closing packet anyway (and segfault). Make sure we have
their signature before trying that.

This is less convenient to use, but makes far more sense for a real
user (like a wallet). It can ask about the route, then decide whether
to use it or not.
This will make even more sense once we add a parameter to control how
long we let the HTLC be delayed for, so a client can query for high,
medium and low tolerances and compare results.

We stopped automatically retransmitting locally-generated add/removes
after a reconnect, but this breaks the "pay" interface as it stands.
The correct solution to this is to make the pay interface idempotent:
you can trigger it as many times as you want and it will only succeed
once.

If we've not relayed a failure yet (ie. we relayed it instantly, but it

It's not currently encrypted, but at least you get some idea now why

These low level commands we restarted on reconnect for ease of
testing. Don't do that, and check that we're connected when those
commands occur.
This introduces subtle issues with --manual-commit --reconnect: restarting
node1 also forgets uncommitted things from node2, requiring reordering for
some tests.

If we send an HTLC #1, then get disconnected before a confirm, we will
forget it. But we've incremented peer->htlc_id_counter, so when we offer
it again we'll make it HTLC #2, which is non-consecutive.
To make this clear, we always start htlc ids at 0 now. That revealed
the bugs handled in the previous patch.

I originally overloaded struct htlc for this, as they go through the
same states, but separating them turned out to be clearer.
