This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

`wallet_payment_store` would free the `wallet_payment` instance which would
then cause us to reload it from the DB. Instead of doing the store->free->load
dance we now tell `wallet_payment_store` whether it should take ownership and
leave it alone if not.
Passing the payment around instead of referencing it through payment_hash and
partid is a nice side-effect.
This is in preparation for partial payments. For existing payments,
partid is 0 (arbitrarity) and total_msat is msatoshi.

pPayment field includes the basic information of the payment, so the return valves of 'sendpay_success()' and 'sendpay_fail()' should include this field.
Note "immediate_routing_failure" is before payment creation, and for this case, return won't include payment fields.
`sendpay_success`
A notification for topic `sendpay_success` is sent every time a sendpay
success(with `complete` status). The json is same as the return value of
command `sendpay`/`waitsendpay` when these cammand succeeds.

}
}
```
`sendpay` doesn't wait for the result of sendpay and `waitsendpay`
returns the result of sendpay in specified time or timeout, but
`sendpay_success` will always return the result anytime when sendpay
successes if is was subscribed.
Now we don't have a second caller for these routines, we can move
them back into pay.c and make the functions static.

As a general rule, lightningd shouldn't parse user packets. We move the
parsing into gossipd, and have it respond only to permanent failures.
Note that we should *not* unconditionally remove a channel on
WIRE_INVALID_ONION_HMAC, as this can be triggered (and we do!) by
feeding sendpay a route with an incorrect pubkey.

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).

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