It needs to save them to the db in case of restart; this means we tell
it about funding_locked, as well as the next_per_commit_point given
in revoke_and_ack.

The channel daemon gets the shared secrets from the HSM to save
the master daemon some work. It used to hand these over at
revoke_and_ack receive, which is when the master daemon needs them.
However, it's a bit simpler to hand them over when we first tell
the master about the incoming HTLC (the first commitsig).

They share some fields, but they're basically different, and it's clearest
to treat them differently in most places.

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.
