jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.
Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.

If send_htlc_out() fails, it doesn't initialize pc->out; that can
make us think it's still in progress.

This addresses a performance regression introduced by
6ceb375650. We were storing it in an
otherwise empty DB transaction, which means that DB transaction was no
longer a no-op. Now we defer storing until we need to store the
corresponding HTLC anyway, so we can just piggyback on top of that
transaction.
This is also more consistent since we'd be forgetting the payment
anyway if we restart between adding the HTLC and committing to it.

Using pc after free in the pay_command_destroyed destructor, so
we just steal cmd onto pc so free order is the one we want.

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

It's a bit tricky since we want to hand more verbose errors to the local
case, but the locally-created and forwarded paths had diverged (the local
one missing some things).

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.
