Paid invoices need to know how much was actually paid: both for the case
where no 'msatoshi' amount was specified, and for the normal case, where
clients are permitted to overpay in order to help them disguise their
payments.
While we migrate the db, we leave this field as 0 for old paid
invoices. This is unhelpful for accounting, but at least clearly
indicates what happened if we find this in the wild.

'rhash' is the old terminology, but 'payment_preimage' and
'payment_hash' were decided on for the BOLTs, so we should fix that here.
We still use rhash internally, but that's much easier to fix.

1) Note incorrect label in txs in Fig1 of LN paper.
2) "an atomic-swap an on-chain.." -> "an atomic-swap *to* an on-chain"
3) "By using a dual anchor and escape transactions" -> "By using a rebalanced single anchor"
4) References to appendices fixed.
5) Move escape transaction scripts out to escape appendix.
6) Fix URL in bibliography (missing comma).

We can save an opcode in both HTLC send and receive scripts by using
OP_2DROP instead of OP_DROP twice.

StephenM347 on #lightning-dev indicated it could be clearer that
this is all about changing commitment transactions.

It's slightly clearer to do the "2" outside the branch.
Also, spending it requires the extra 0 due to OP_CHECKMULTISIG bug.

As reported by mmeijeri on r/Bitcoin:

As the signature doesn't cover the input itself, you could replace the
secret key from the escape transaction with 0, and it will use the "A and B"
branch of the output.
(This also fixes a bug in the anchor output where the OP_IF consumed the
secret).
