Description Eike Stepper CLA 2013-02-10 00:17:13 EST 
CDOObjectImpl used to store the view, state, id and revision in 4 different instance fields. Observations:

1) All objects of a view share a small number of CDOState literals. 
2) if a revision is set, the object's ID is equal to the revision's ID.

The is to pack the resulting combinations into these 2 fields and adjust the getters and setters accordingly:

  private ViewAndState viewAndState = ViewAndState.TRANSIENT;
  private Object idOrRevision;
