Also based on pettycoin code.
(With embarrassing bug fixed where it didn't increment the address used,
thus using 100% CPU if that connect failed!)

For better or worse, the ccan/timer structure is completely minimal,
and designed to be wrapped inside a container structure.

We don't want to re-create them internally, ever.
The test-cli tools are patched to generate them all the time, but
they're not performance critical.

This is used for figuring out the close transaction balances,
but can also be used in the future for dynamic fee support.

Use our own structure with the information we need about HTLCs,
and remove protobufs from the API.
The is_funder() helper goes inside gather_updates.h.

Hand anchor details and pubkeys directly; this is what we want
for the actual daemon which doesn't keep raw packets around.

We have to sign the commit at this stage, so easiest if peer isn't const
so we can sign it in-place.

This tell us to disarm the INPUT_CLOSE_COMPLETE_TIMEOUT: either we hit
an error and are going to unilateral close, or we received their signature
successfully.

Actually generating the anchor transaction in my implementation
requires interaction with bitcoind, which we want to be async. So add
a callback and a new state to wait for it.

We use both union fields idata->btc and idata->htlc, which is clearly
wrong. Have peer_tx_revealed_r_value return the HTLC it's talking
about.

This lets us eliminate struct state_effect altogether (the next patch
removes the now-unused arguments).

We only have one htlc in flight at a time, but sometimes it changes:
particularly when we are lowpriority and a highpriority request comes
in. Handle this using a set of callbacks for htlc handling.

Now we're covered by the opening command anyway, and the rule that you
can't have two commands at once.
There are two more defers:
1) In state STATE_WAIT_FOR_UPDATE_SIG_LOWPRIO/HIGHPRIO we are waiting for
their signature because they started an HTLC, we defer any new HTLC
creation, and
2) We defer PKT_OPEN_COMPLETE when we're waiting for anchor depth.
The first can be solved by a flag indicating whether we are accepting new
commands at all, the second by a pair of new states.

This is conceptually cleaner, especially since it means we're running
a command until we're set up (which prevents other commands, so no
special case needed).
