Peter Maydell e54c24339f include/qom/object.h: New OBJECT_DEFINE_SIMPLE_TYPE{, _WITH_INTERFACES} macros ... We have an OBJECT_DEFINE_TYPE_EXTENDED macro, plus several variations on it, which emits the boilerplate for the TypeInfo and ensures it is registered with the type system. However, all the existing macros insist that the type being defined has its own FooClass struct, so they aren't useful for the common case of a simple leaf class which doesn't have any new methods or any other need for its own class struct (that is, for the kind of type that OBJECT_DECLARE_SIMPLE_TYPE declares). Pull the actual implementation of OBJECT_DEFINE_TYPE_EXTENDED out into a new DO_OBJECT_DEFINE_TYPE_EXTENDED which parameterizes the value we use for the class_size field. This lets us add a new OBJECT_DEFINE_SIMPLE_TYPE which does the same job as the various existing OBJECT_DEFINE_*_TYPE_* family macros for this kind of simple type, and the variant OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES for when the type will implement some interfaces.
