1. htlc->fail has been changed to a u8 *.
2. wallet_get_newindex saves to the db.
3. peer->next_htlc_id is saved to the db in peer_save_commitsig_sent() below.
4. We do store commit in peer_save_commitsig_received(peer, commitnum),
   and the fixme below talks about HTLC sigs.
5. We do commit shachain and next_per_commit_point in wallet_shachain_add_hash
   and update_per_commit_point respectively.

93c589efe8 wallet: save block height when we first create channel.
This gives us a lower bound on where funding tx could be.

In theory, it could be lower than this if we get a reorganization, but
in practice this is already a 1-block buffer (since we can't get into
current block, only the next one).

810abb6b21 bitcoin: create new wrapper type bitcoin_blkid, log backward endianness.
It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

3543530172 build_utxos: fix weight calculation, and make more accurate.
Accuracy improvements:

1. We assumed the output was a p2wpkh, but it can be user-supplied now.
2. We assumed we always had change; remove this for wallet_select_all.

Calculation out-by-one fixes:

1. We need to add 1 byte (4 sipa) for the input count.
2. We need to add 1 byte (4 sipa) for the output count.
3. We need to add 1 byte (4 sipa) for the output script length for each output.
4. We need to add 1 byte (4 sipa) for the input script length for each input.
5. We need to add 1 byte (4 sipa) for the PUSH optcode for each P2SH input.

The results are now a slight overestimate (due to guessing 73 bytes
for signature, whereas they're 71 or 72 in practice).

8c665835fa jsonrpc: make explicit call to indicate cmd is still pending.
jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something

94711969f9 gossipd: hand out gossip_index to other daemons.
When gossipd sends a message, have a gossip_index.  When it gets back a
peer, the current gossip_index is included, so it can know exactly where
it's up to.

Most of this is mechanical plumbing through openingd, channeld and closingd,
even though openingd and closingd don't (currently) read gossip, so their
gossip_index will be unchanged.

67aa95c194 gossipd: hand back peer, don't hand a new peer.
All peers come from gossipd, and maintain an fd to talk to it.  Sometimes
we hand the peer back, but to avoid a race, we always recreated it.

The race was that a daemon closed the gossip_fd, which made gossipd
forget the peer, then master handed the peer back to gossipd.  We stop
the race by never closing the gossipfd, but hand it back to gossipd
for closing.

Now gossipd has to accept two fds, but the handling of peers is far
clearer.
