Rusty Russell 2da5244e83 jsonrpc: make error codes an enum.
This allows GDB to print values, but also allows us to use them in
'case' statements.  This wasn't allowed before because they're not
constant terms.

This also made it clear there's a clash between two error codes,
so move one.

Rusty Russell 5065bd6fc2 lightningd: use our cached channel_update for errors instead of asking gossipd.
We also no longer strip the type off: everyone handles both forms, and
Eclair doesn't strip (and it's easier!).

Rusty Russell 4eb1233ccb lightningd: don't report spurious temporary_node_failure on local failures.
I noticed the following in logs for tests/test_connection.py::test_feerate_stress:

```
DEBUG 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: Failing HTLC 18446744073709551615 due to peer death
DEBUG 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: local_routing_failure: 8194 (WIRE_TEMPORARY_NODE_FAILURE)
```

This is because it reports the (transient) node_failure error, because
our channel_failure message is incomplete.  Fix this wart up.

Vasil Dimov 55173a56b7 Use dedicated type for error codes
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.

To resolve this:

* Introduce an error code type with a known size:
  `typedef s32 errcode_t`.

* Change all error code macros to constants of type `errcode_t`.
  Constants also play better with gdb - it would visualize the name of
  the constant instead of the numeric value.

* Change all functions that take error codes to take the new type
  `errcode_t` instead of `int`.

* Introduce towire / fromwire functions to send / receive the newly added
  type `errcode_t` and use it instead of `towire_int()`.

In addition:

* Remove the now unneeded `towire_int()`.

* Replace a hardcoded error code `-2` with a new constant
  `INVOICE_EXPIRED_DURING_WAIT` (903).

Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2

Rusty Russell 1099f6a5e1 common: use struct onionreply.
This makes it clear we're dealing with a message which is a wrapped error
reply (needing unwrap_onionreply), not an already-wrapped one.

Christian Decker 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.

Rusty Russell 2d18c3a209 db: add partid, total_msat fields to payment entries.
This is in preparation for partial payments.  For existing payments,
partid is 0 (arbitrarity) and total_msat is msatoshi.

trueptolemy 9d8f46149a API: Add payment fields(if not NULL) into return value when sendpay fails
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.

trueptolemy 07f85cbf72 plugin: A new notification type, 'sendpay_success'
`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.

```json
{
	"sendpay_success": {
  "id": 1,
  "payment_hash": "5c85bf402b87d4860f4a728e2e58a2418bda92cd7aea0ce494f11670cfbfb206",
  "destination": "035d2b1192dfba134e10e540875d366ebc8bc353d5aa766b80c090b39c3a5d885d",
  "msatoshi": 100000000,
  "amount_msat": "100000000msat",
  "msatoshi_sent": 100001001,
  "amount_sent_msat": "100001001msat",
  "created_at": 1561390572,
  "status": "complete",
  "payment_preimage": "9540d98095fd7f37687ebb7759e733934234d4f934e34433d4998a37de3733ee"
  }
}
```
`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.

Rusty Russell afab1f7b3c gossipd: handle onion errors internally.
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.
