`pay_index` has no valid value if not PAID anyway, so
we should correctly leave it uninitialized.
Analysis via valgrind will catch incorrect use of
uninitialized fields.
If we load it with a dummy 0 value, then an
incorrect use of `pay_index` whan invoice is not
PAID will not get caught by valgrind.
Seems to avoid the nasty python resource warnings, as well as the
fatal 'ValueError: PyMemoryView_FromBuffer(): info->buf must not be NULL'

When payment fails, we call wallet_payment_set_status; this is perfectly
possible before it's been committed.

For performance, we delay entering the 'wallet_payment' into the db
until we actually commit to the HTLC (when we have to touch the DB
anyway).
This opens a race where we can try to pay twice, and since it's not in
the database yet, we don't notice the duplicate.
So remove the temporary payment field from htlc_out, which was always
an uncomfortable hack, and make the wallet code abstract over the
deferred entry a little by maintaining a 'unstored_payments' list
and incorporating that in results.

We could do this lazily, if HTLC errors out, but we do it as HTLCs
come in in the normal case, so this is slightly simpler.

We need these to decode any returned errors.
We remove it from struct pay_command too, and load directly from db
when we need it.

We should be saving this, as it's our proof of payment. Also, we return
it if they try to pay again.

This, of course, should never be used. But it helps maintain connections
for the moment while we dig deeper into feerates.

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.

This means we print out the correct path with --debugger, which
can be vital if there are multiple binaries (eg. compiled vs installed).

permute_outputs is sometimes called with empty arguments from initial_commit_tx.
Make sure we guard against that case. We also do the same in permute_inputs for
good measure.
