I'm not completely convinced that it's only ever set to a failcode with the BADONION bit set, especially after the previous patches in this series. Now that channeld can handle arbitrary failcodes passed this way, simply rename it. We add marshalling assertions that only one of failcode and failreason is set, and we unmarshal an empty 'fail' to NULL (just the the generated unmarshalling code does).
