NEWT Fixes:

- Common native in NewtCommon.c/.h

- Add simple NEWTEventFiFo, providing a pattern
  to spool events by an EventListener and to process them
  where it impacts (GLEventListener ..)

- Window [X11|Windows]: setSize/setPosition:
    - always store the values,
    - only act if valid and !fullscreen

- Window [X11]:
    - Add requestFocus
    - Add setTitle
    - Fix parent/child window creation
    - Fix parent/child window fullscreen (reparenting)

- JUnit Test: ParentTest:
    - Shows parent and client window animation

    - Client window shall be able to go into fullscreen,
      ie disconnect/reconnect from its parent.
      Test: Focus-client + type-'f'

    - Both windows receive/dispatch events properly
