602117e8bb Add valgrind memcheck helpers. 
Otherwise valgrind tells you when you test a hash; you want to
know if you hash uninitialized memory long before that.

9f12b72476 Don't include mutual redemption in recovable commit tx output. 
It's not clear it's needed, and without it there's a good reason to
delay dumping to the blockchain if a node becomes unreachable (since
you'll get your money faster if it comes back online).

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.
