Rusty Russell	ec3344ce6e	daemon/output_to_htlc: routines to map outputs for HTLCs for a given commit_num. And use this to resolve old transactions by comparing outputs with HTLCs. Rather than remembering the output ordering for every one of their previous commitment transactions, we just remember the commitment number for each commitment txid, and when we see it, derive all the HTLC scriptpubkeys and the to-us and to-them scriptpubkeys, and figure out which is which. This avoids us having to save information on disk, except for the txid->commitment-number mapping (and the shachain). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	9 years ago

daemon/output_to_htlc: routines to map outputs for HTLCs for a given commit_num.

And use this to resolve old transactions by comparing outputs with
HTLCs.

Rather than remembering the output ordering for every one of their
previous commitment transactions, we just remember the commitment
number for each commitment txid, and when we see it, derive all the
HTLC scriptpubkeys and the to-us and to-them scriptpubkeys, and figure
out which is which.

This avoids us having to save information on disk, except for the
txid->commitment-number mapping (and the shachain).
