    Reviews EDTUtil API and usage:
      - less confusing / more determined EDTUtil API
      - EDTUtil's thread shall only be reset and started when required (-> lazy)
      - EDTUtil's instance in Display shall be handled thread safe w/o extra blocking
      - EDTUtil's implementations (Default, SWT and AWT) shall be aligned / similar as much as possible
    
    Further note: SWT's EDTUtil (NewtCanvasSWT) shall not use a reused Display instance due to it's
                  custom SWTEDTUtil. We may need to disable the ref. cache if custom EDTUtil (setEDTUtil)
                  is intended (used).
