JOGL refactoring:

    Refactored JOGL into 3 independent components.

    1 NWI - Native windowing interface
        Abstracts the the general NativeWindow interface and it's factory,
        incl the basic JAWT and Xlib toolkit.
        The latter was motivated to clean up the JOGL workspace,
        and to allow other to reuse this part.
        The generic core is nwi.core.jar, the AWT add-on is nwi.awt.jar.

    2 JOGL - The OpenGL mapping
        Further cleanup of the SPEC.
        All non OpenGL toolkits are relocated to NWI and NEWT.
        There is still openmax and the windows audio layer ..
        Another cleanup of the fixed function pipeline emulation.
        Moved utilities and implementations where they belong ..
        Removed GLUnsupportedException.
        Misc .. changes

    3 NEWT - The new windowing toolkit
        The generic NEWT, newt.core.jar.
        The JOGL and AWT modules are seperate, newt.ogl.jar newt.awt.jar.
        Their build can be switched off.

    The modules source and builds resides in their own directory.
    Because of their nature, they share the stub_includes, etc.
    Each module has it's own ant build script
        - build-nwi.xml
        - build-jogl.xml
        - build-newt.xml
    They can be build at once using build.xml as ususal,
    which just invokes the seperate build tasks.

    if rootrel.build=build, then the build location is
        jogl/build-nwi
        jogl/build-jogl
        jogl/build-newt
    and the sources are under
        jogl/src/nwi
        jogl/src/jogl
        jogl/src/newt

    Tested: jogl-demos, d4; Linux, MacOsX; Nvidia
