5319ff1bc0 bitcoind: Do not crash when getblock fails
This is a common occurence on pruned nodes. By calling the callback
upon failures, we communicate that we couldn't verify the txoutput. We
fail safe rejecting any channel we can't verify.

3a42e52bcd gossip: Fix a memcmp with unset memory in broadcast queue
`tal_fmt` overallocates the returned string under some circumstances,
meaning that the trailer of the formatted string is unset, but still
considered in `tal_len`. The solution then is to truncate the
formatted string to the real string length. Only necessary here, since
we mix strings and `tal_len`.

2f2fb0c2a1 invoice: add msatoshi_received field.
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.

66885163c9 JSON: Rename rhash to payment_hash in delinvoice, invoice, listinvoice, waitinvoice, waitanyinvoice.
'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.
