1273b842d2 lightningd: fix reorg bug where we don't fire watches.
If the same memory gets reallocated, our "has the tip changed?" test
gets a false negative.  This happened for me about one time in 10,
causing tests/test_misc.py::test_funding_reorg_remote_lags to fail.

8eda489ae2 lightningd: don't stop processing revoke_and_ack if an HTLC is invalid.
This shouldn't happen if channeld is working properly, but I'm going to
change that, and this current code means we stop responding at that point
(not every failpath in peer_accepted_htlc() called channel_internal_error).

bfcef9002e lightningd: fix handling of WIRE_UPDATE_FAIL_MALFORMED_HTLC.
1. We asserted that there wouldn't be a raw failcode.
2. We didn't pass the failure information via JSON in this case.

c11212bb52 pytest: test that we handle WIRE_UPDATE_FAIL_MALFORMED_HTLC correctly.
We could use sendonion to do this, but it actually takes a different path through
pay, and I wanted to test all of it, so I made a new dev flag.

We currently get upset with the response:

	lightningd/pay.c:556: payment_failed: Assertion `!hout->failcode' failed.

262e4c840f sphinx: use struct secret for shared secret.
Generally I prefer structures over u8, since the size is enforced at
runtime; and in several places we were doing conversions as the code
using Sphinx does treat struct secret as type of the secret.

Note that passing an array is the same as passing the address, so
changing from 'u8 secret[32]' to 'struct secret secret' means various
'secret' parameters change to '&secret'.  Technically, '&secret' also
would have worked before, since '&' is a noop on array, but that's
always seemed a bit weird.

4be1868b8a pay: Invert ownership of wallet_payment
`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.

Indeed, if you waitsendpay without specifying a partid, you are waiting
for 0, which may not exist.  Clarify the error msg.

We only tested exactly two equal-size payments; indeed, our finalhop
test was backwards.  We only complain if the final hop pays more than
twice msat (technically, this test is still too loose for mpp: the
spec says we should sum to the exact amount).
