* The clone visitor is for direct use only by the QAPI_CLONE() macro;
* it requires that the root visit occur on an object, list, or
* alternate, and is not usable directly on built-in QAPI types.
typedef struct QapiCloneVisitor QapiCloneVisitor;
void *qapi_clone(const void *src, void (*visit_type)(Visitor *, const char *,

* Deep-clone QAPI object @src of the given @type, and return the result.
* Not usable on QAPI scalars (integers, strings, enums), nor on a
* QAPI object that references the 'any' type. Safe when @src is NULL.
