Subject: Analysis of glXMakeCurrent freeze on ATI fglrx 8.78.6; Misc ..

Analysis of glXMakeCurrent freeze on ATI fglrx 8.78.6
    - Workaround in TestGLWindows01NEWT: same create/destroy order
    - Prove bug with simple native test app: jogl/test/native/displayMultiple02.c

Misc:
    - Reverted d52181032830acdd5e4069a41ccd0daff5922d8a, ie reenable x11IOErrorHandler (nativewindow)
    - GLDrawableHelper: methods -> final
    - X11Util.NamedDisplay: remove unused RecursiveLock, Cloneable
