proto_to_locktime: abs and relative locktime handlers.

protocol: rename locktime fields to "delay" and "expiry"
For open transactions, locktime is a delay we require on the other
side's to-self commit transaction outputs to ensure we can cut them
off if necessary.
For HTLCs, it's an absolute expiry time.

protocol: add commitment fee logic.
Both sides elect a commitment fee, and the lowest is chosen. That means
you can't game the other side (but if you offer too low, then can error
out of course).
Fees are split 50-50 if possible: originally the whole fee has to be
paid by the (single) funder. Neither side can withdraw funds which
would make them unable to pay fees.

case anything goes wrong; these will be revoked later.
