From: ZheNing Hu <adlternative@xxxxxxxxx> When we use ref_array_item which is not dynamically allocated and want to free the space of its member "value" after the end of use, free_array_item() does not meet our needs, because it tries to free ref_array_item itself and its member "symref". Introduce free_ref_array_item_value() for freeing ref_array_item value. It will be called internally by free_array_item(), and it will help `cat-file --batch` free ref_array_item's value memory later.
