NEWT/AWT Focus traversal enhancement/fix (incl. OS X fixes)

- MacWindow/OffscreeSurface
  - Exclude native NEWT window calls in case it's an offscreen surface

- MacWindow/DriverClearFocus
  - Introduce driver detail DriverClearFocus interface
  - OS X needs to clear the focus, before another TK (eg. AWT) can claim it's (native parent window focus)

- MacWindow/KeyCode:
  - Move OS X keyCode utils to MacKeyUtil
  - MacKeyUtil now uses OS X virtual key codes first, before matching keyChar -> keyCode

- NewtCanvasAWT
  - Issue all AWT 'requestFocus()' on current thread,
    Newt-EDT -> AWT-EDT may freeze Window's native peer requestFocus() impl.

  - FocusAction directly issue action on Newt-EDT,
    also request AWT focus if not having it (proper AWT traversal)

  - Add an FocusPropertyChangeListener, detecting focus lost
    to issue DriverClearFocus's clearFocus() if available.

  - merge configureNewtChildInputEventHandler() code into configureNewtChild()
    to simplify call tree.

- WindowImplAccess: Use getDelegatedWindow()
