When we see an offered HTLC onchain, we need to use the preimage if we know it. So we dump all the known HTLC preimages at startup, and send new ones as we discover them. This doesn't cover preimages we know because we're the final recipient; that can happen if an HTLC hasn't been irrevocably committed yet. We'll do that in a followup patch.
