NEWT: Focus Fix + Cleanup

Issueing 'requestFocus' via the native EDT dispatch loop may cause a deadlock,
due to a possible implicite AWT requestFocus call (NewtCanvasAWT).

Approach:
    RequestFocus issued directly,
    by Window.requestFocus() and the native EDT dispatch loop,
    is queued for later execution by EDT.
    This shall decouple a possible native windowing TK resource collision.

- X11Windows.c: Add missing 'reparented' param for requestFocus
  to force requestFocus after reparenting.

- AWTWindow.java: Add requestFocusImpl()
