Today, the Seq.Ref class has two purposes. For Java references,
Ref contains the refnum, a reference to the Java object and a
reference count. For Go references, Ref contains the refnum and
its finalizer makes sure to decrement the reference count on the Go
side.
The next CL will replace the use of finalizers with an explicit
ReferenceQueue of Go references, and the Ref class will no longer
be used for Go refences. To prepare for that, this CL pulls up the
construction of Go referencing Ref instances into the Seq.trackGoRef
function.
