And store in peer->last_tx/peer->last_sig like all other places,
that way we broadcast it if we need to.
Note: the removal of tmpctx in funder_channel() is needed because we
use txs[0], which was allocated off tmpctx.

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).

It's a bit tricky since we want to hand more verbose errors to the local
case, but the locally-created and forwarded paths had diverged (the local
one missing some things).

We need this for reestablishing a channel.
(Note: this patch changes quite a bit in this series, but reshuffling was
tedious).

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.

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.
