When adding their HTLCs, it needs all the information. When failing, it needs the id as key and the failure reason. When fulfilling, it needs the id and payment preimage. It also needs to know when we have received an revoke_and_ack or a commitment_signed, to place in the database. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
