Paolo Bonzini 7bd8e3ef63 rust: qom: split ObjectType from ObjectImpl trait ... Define a separate trait for fields that also applies to classes that are defined by C code. This makes it possible to add metadata to core classes, which has multiple uses: - it makes it possible to access the parent struct's TYPE_* for types that are defined in Rust code, and to avoid repeating it in every subclass - implementors of ObjectType will be allowed to implement the IsA<> trait and therefore to perform typesafe casts from one class to another. - in the future, an ObjectType could be created with Foo::new() in a type-safe manner, without having to pass a TYPE_* constant.
