Dylan Reid a1f408a247 qcow: bounds check the refcount table offset and size ... If the header puts the refcount table outside the file size or if it specifies a table much larger than needed, fail to open the file. These might not be hard qcow errors, but they are situations that crosvm will never encounter. BUG=986061 TEST=fuzzer with new test cases completes in less than 5 seconds.
