Subject: [PATCH 09/18] Lib/Octave: in Octave >= 4.4, assign reference to base
 class in subclass

- See Examples/octave/callback/runme.m: a.run() calls Octave callback,
  but due to changes in behaviour to subsref() a.Callback.run() can no
  longer be used to call C callback unless a.Callback actually exists;
  subsrefs() just gets the "Callback" call whereas prior to Octave 4.4
  it would get both the "Callback" and "run" calls. So now a.Callback is
  set to the original base class (with own=0) so that it can be accessed
