We need the old remote per_commitment_point so we can validate the per_commitment_secret when we get it. We unify this housekeeping in the master daemon using update_per_commit_point(). This patch also saves whether remote funding is locked, and disallows doing that twice (channeld should ignore it). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
