Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.
It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
We call channel_sent_commit *before* sending (so we know if we need
to), so the name is wrong. Similarly channel_sent_revoke_and_ack.
We can usefully have them tell is if there is outstanding work to do,
too.

Passing through 'struct peer *' was a layering violation.

The three cases we care about only happen on specific transitions:
1. They can no longer spend our failed HTLC: we can fail the source now.
2. They are fully committed to their new HTLC htlc: we can forward now.
3. They can no longer timeout their fulfilled HTLC: the funds are ours.

Now we correctly use the remote revocation basepoint, we need to set
it in run-channel (instead of the local revocation basepoint).
We also update all the comments, as per (pending) spec commit:

All the daemons will use a common seed for point derivation, so drag
it out of lightningd/opening.
This also provide a nice struct wrapper to reduce argument count.

Only minor changes, but I add some more spec text to
lightningd/test/run-commit_tx.c to be sure to catch if it changes
again.
One reference isn't upstream yet, so had to be commented out.

This object is basically the embodyment of BOLT #2. Each HTLC already
knows its own state; this moves them between states and keeps them
consistent.
