Modifies a pointer to point to a new mini-object. The modification
is done atomically. This version is similar to gst.mini_object.MiniObject.replace
except that it does not increase the refcount of newdata and thus
takes ownership of newdata.
Either newdata and the value pointed to by olddata may be null.
