Rusty Russell 6c98457ef2 per-peer seed is a 'struct secret' not a 'struct privkey'.
They're both 32 bytes, but it's not a privkey at all.

Rusty Russell edf1b3cec9 More option cleanups.
Because we have too many which are never used and I don't want to document
them.

1. Remove unused anchor_onchain_wait.  When implemented, it should be
   hardcoded to 100 or more.
2. Remove anchor_confirms_max.  10 always reasonable, and we can readd
   an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
   from 3 to 5 days by default): they're both a limit on how long
   funds can be locked up.
4. channel_update_interval should always be a dev option.

Rusty Russell ab9d9ef3b8 gossipd: drain fd instead of passing around gossip index.
(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 :(

Rusty Russell cfa50d393a openingd: use peer_failed like normal instead of boutique negotiation_failed.
Because peer_failed would previously drop the connection, we had a
special 'negotiation_failed' message which made the master hand it
back to gossipd.  We don't need that any more.

This also meant we no longer need a special hook in read_peer_msg
for openingd to send this message.

Rusty Russell 0237e0b28c bitcoin: create new wrapper type bitcoin_txid, 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_txid_to_hex() so it's reversed as people expect.

Rusty Russell 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.

For our own internal comms CSVs, we should always name explicit types.

Rusty Russell 72b215f6fe Make all internal message numbers unique.
We were sending a channeld message to onchaind, which was v. confusing
due to overlap.  We make all the numbers distinct, which means we can
also add an assert() that it's valid for that daemon, which catches
such errors immediately.

Rusty Russell ef28b6112c status: use common status codes for all the failures.
This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.

It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).
