NativeWindow/Newt X11ErrorHandler enhancement / unification - don't throw exceptions. Handles also XAWT BadMatch X_SetInputFocus.

X11ErrorHandler code now dumps proper information about the opcode and error message and the running Java thread.

Having propery "nativewindow.debug.X11Util.XErrorStackDump" or "nativewindow.debug=all' set,
a stack trace is dumped.

Since the X11ErrorHandler may catch an XAWT error: BadMatch X_SetInputFocus,
we cannot throw an exception and better keep running.
