Since we only care about the latest commits, we can simply associate a
state with each HTLC, rather than using queues of HTLCs associated
with each commitment transaction.
This works far better in the context of a database.

This is generally redundant, since HTLC pointer is in that side's
commit_info, but makes HTLC completely self-contained.

Thus a node MUST estimate the deadline for successful redemption for
each HTLC it offers. A node MUST NOT offer a HTLC after this
deadline, and MUST fail the connection if an HTLC which it offered is
in either node's current commitment transaction past this deadline.

We currently keep copies of HTLCs in each commit_info structure, but
that's redundant. Keep per-peer per-direction maps of HTLCs, then we can
just throw pointers around (next patch).
