Oh dear, where to start. There's so much wrong, and in pretty obvious
ways. This code should never have passed review. I'm refraining from
saying more; see the commit messages instead.
Issues remaining after this series include:
* Terrible error messages
* Some error message cascades remain
* There is no written contract for QEMUFileHooks, and the
responsibility for reporting errors is unclear
* There seem to be no tests whatsoever
