we used this originally to suppress duplicate issuance of coin-move
events; we're assuming that any plugin expects duplicate events though
(and knows how to de-dupe them), so we no longer need this logic.
On node start we replay onchaind's transactions from the database/from
our loaded htlc table. To keep things tidy, we shouldn't notify the
ledger about these, so we wrap pretty much everything in a flag that
tells us whether or not this is a replay.
There's a very small corner case where dust transactions will get missed
if the node crashes after the htlc has been added to the database but
before we've successfully notified onchaind about it.
Notably, most of the obtrusive updates to onchaind wrappings are due to
the fact that we record dust (ignored outputs) before we receive
confirmation of its confirmation.
This will allow us in the next commit to store the transactions that triggered
this event in the DB and thus allowing us to replay them later on.
