This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.
This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined. Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

Changelog-Changed: JSON-RPC: `withdraw` now randomizes input and output order, not BIP69.
Break out a method for canceling a channel that will either
loop through contacting the peer to tell them of the error or
just directly cleans up if the peer is currently disconnected.
Encapsulating the peer state was a win for lightningd; not surprisingly,
it's even more of a win for the other daemons, especially as we want
to add a little gossip information.

These are always handed to subdaemons as a set, so group them. This makes
it easier to add an fd (in the next patch).

1. Rename channel_funding_locked to channel_funding_depth in
channeld/channel_wire.csv.
2. Add minimum_depth in struct channel in common/initial_channel.h and
change corresponding init function: new_initial_channel().
3. Add confirmation_needed in struct peer in channeld/channeld.c.
4. Rename channel_tell_funding_locked to channel_tell_depth.
5. Call channel_tell_depth even if depth < minimum, and still call
lockin_complete in channel_tell_depth, iff depth > minimum_depth.
6. channeld ignore the channel_funding_depth unless its >
minimum_depth(except to update billboard, and set
peer->confirmation_needed = minimum_depth - depth).
Just have a "new depth" callback, and let channeld do the right thing.
This makes the channeld paths a bit more straightforward.

(This was sitting in my gossip-enchancement patch queue, but it simplifies
this set too, so I moved it here).
In 94711969f we added an explicit gossip_index so when gossipd gets
peers back from other daemons, it knows what gossip it has sent (since
gossipd can send gossip after the other daemon is already complete).
This solution is insufficient for the more general case where gossipd
wants to send other messages reliably, so replace it with the other
solution: have gossipd drain the "gossip fd" which the daemon returns.
This turns out to be quite simple, and is probably how I should have
done it originally :(

We missed it in some corner cases where we crashed/were killed between
being told of the lockin and sending the channel_normal_operation message.
When we were restarted, we were told both sides were locked in already,
so we never updated the state.
Pull the entire "tell channeld" logic into channel_control.c, and make
it clear that we need to keep waching if we cant't tell channeld. I think
we did get this correct in practice, since funding_announce_cb has the
same test, but it's better to be clear.
