       Decrement the reference count of a managed object. The m17n_object_unref() function decrements the
       reference count of the managed object pointed to by object. When the reference count becomes zero, the
       object is freed by its freer function.

           This function never fails.

           This function returns the resulting reference count if it fits in a 16-bit unsigned integer (i.e.
           less than 0x10000). Otherwise, it returns -1. Thus, the return value zero means that object is freed.
