- Fix: X11 locking The current thread default display or the given display is being used, hence it is no more required to use a ToolkitLock for X11 without AWT.

Removed X11 ToolkitLock in case of X11 without AWT,
    which is being detected with the absence of the classes
        java.awt.Component _AND_ javax.media.nativewindow.awt.AWTGraphicsDevice
    or with the system property
        java.awt.headless=true

    Only in the Java2D/Swing case, one 'leaking' Display
    is created within canCreateGLPbuffer().

- Workaround for Hotsport bugs #4395095, #6852404
    4395095 JNI access to java.nio DirectBuffer constructor/accessor
    6852404 Race condition in JNI Direct Buffer access and creation routines

- Added build.xml
    -Dbuild.noarchives=true property to skip the time consuming
    creation of zip archives.
