Modifies a pointer to point to a new mini-object. The modification
is done atomically. This version is similar to gst_mini_object_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.
