Native free callback of an object. It is used in `jerry_object_native_info_t` and for external Array buffers.

## jerry_object_native_free_callback_t
**Summary**
Native free callback of an object. The callback receives both the memory pointer and the type
information passed to [jerry_set_object_native_pointer](#jerry_set_object_native_pointer).
*Note*:
- Referred values by this method must have at least 1 reference. (Correct API usage satisfies this condition)
**Prototype**
```c
typedef void (*jerry_object_native_free_callback_t) (void *native_p, struct jerry_object_native_info_t *info_p);
```
- `native_p` - native pointer passed to [jerry_set_object_native_pointer](#jerry_set_object_native_pointer).
- `info_p` - native type info passed to [jerry_set_object_native_pointer](#jerry_set_object_native_pointer).
*New in version 2.0*: Renamed from `jerry_object_free_callback_t`.
*Changed in version 2.2*: API calls are once again allowed. (See note)
*Changed in version [[NEXT_RELEASE]]*: `info_p` argument is added
