Remove signature leaking.
Alpha has segregated witnesses, so txid doesn't include the inputs.
That means we can create the first commit transaction before we sign
the anchor tx.
Bitcoin will need to do this differently: presumbly via new sipops
(a OP_CHECKSIG2VERIFY I imagine).

protocol fix: use locktime from *other* side.
Which emerged clearly when setting one side's locktime differently than
the other.
Each side specifies the (minimum) time they need to notice a fraud attempt:
this constrains the *other* side.
