In the case where we can't decrypt the onion, we can't fail it in the
normal way (which is encrypted using the onion shared secret), we need
to respond with a update_fail_malformed_htlc message.
Moreover, we need to remember this for persistence. This means that
we really have three conclusions for an HTLC: fulfilled, failed,
malformed. Fix up the logic everywhere which assumed failed or
fulfilled.

They share some fields, but they're basically different, and it's clearest
to treat them differently in most places.

When adding their HTLCs, it needs all the information. When failing,
it needs the id as key and the failure reason. When fulfilling, it
needs the id and payment preimage.
It also needs to know when we have received an revoke_and_ack or a
commitment_signed, to place in the database.

We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

This was overly complex since it was off-by-one and we were storing
some information elsewhere. Now this just loads the route as is into
structs, extracts some information for our outgoing HTLC, and then
shifts by the array of structs by one, and finally fills in the last
instruction, which is the terminal.
This moves all the non-legacy blackbox testing into python.

Note that this doesn't valgrind the subdaemons: that patch seems to cause
some issues in the python framework which I am still chasing.
