28ea518182 create-steal-tx: use o1 to double-check final key is correct. 
It's actually an unused parameter, but they symmetry with others in nice.

ed3f0115d6 protocol: fix horribly thinko, keep own secrets. 
I had each side using the other side's hash secret.  That's a very
dumb idea, since it means you can steal from a unilateral close!

A's secret applies to A's commit transaction: it needs the
secret and B's final signature to steal funds, and that should
never happen (since A doesn't have the B's final signature, and
once A has given B the secret, they never broadcast the commit tx).

This makes the update a 4 step dance, since you need the new
revocation hash to make the other side's TX to sign.

29d0cdc3cd open-channel: use pubkey, not arbitrary script for final outout address. 
We need to pay to this from two places: on their side, it's a simple
payment, on our side, it's a complex timeout-or-mutual-or-hval script,
which doesn't lend itself to arbitrary scripts.

Use P2SH, of course.

f7f7f3f1bb check-anchor-scriptsigs: don't require txs. 
It's convenient to double-check that commit txs spend anchor, but it's
misleading since we wouldn't have access to the other side's tx, and
in practice we wouldn't even sign ours until we need it.
