It's not currently encrypted, but at least you get some idea now why
an HTLC failed. We (ab)use HTTP error codes for the moment.

We don't have an ordering of HTLCs between peers: we don't know
whether your HTLC 0 or my HTLC 0 occurred first. This matters,
as we play them all back to reconstruct state (probably overkill anyway).
So we add force_* operators which don't do bounds checks, and do
bounds checks at the end. We also note that we don't need to apply
fee changes: that should be in the database already.
Also relax db constraints: IDs are not unique, they are unique per
side (we can both have HTLC #0).

I originally overloaded struct htlc for this, as they go through the
same states, but separating them turned out to be clearer.

This makes more sense eventually: we may know the network addresses of
many peers, not just those we're connecting to. So keep a mapping, and
update it when we successfully connect outwards.
