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.

For non-delayed HTLC success spends, we have a similar pattern ("<sig>
<preimage> <wscript>") so a we want to use the same function.
The other routines don't say "witness" in them, and should.

This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.
It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).

This was causing some compilation trouble on 32bit systems, see #256.
