Changed NEWT NativeWindow creation contract - AWT/NEWT Parenting - Misc Fixes

+++++

Changed NEWT NativeWindow creation contract

Original contract:

(1) A native window was created as soon as possible,
    ie when NEWTFactory.createWindow(..) was called - if possible.

(2) A valid native window has to be created at least after setVisible(true)
    has been called.

Problems:
    Not all implementation are able to create the native window that early,
    but at setVisible(true) only (e.g: KD and EGL).

    Due to window parenting especially the new AWT/NEWT parenting,
    the native window can only be created in case the parent native window is valid.

New contract:

(1) A native window is created at setVisible(true),
    if it's a top level window or the native parent window is valid.

(2) A valid native window may not be created after setVisible(true)
    has been called.
    Subsequent setVisible(true) calls shall be made in case
    the creation has not been done yet.
    This is demonstrated in GLWindow.display() for example.

The new contract implements a lazy native window creation.

AWT/NEWT Parenting

- HierarchyListener and ComponentListener ensure that the NEWT child window
  will be setVisible according to the AWT parent window.

- Lazy native window creation relaxes requirements to the parent window's state.

- Attachment of the child window and setVisible() may be called
  after NEWT child window creation.

- GLWindow supports NEWT child window creation directly

The test case TestParenting01AWT.java reflect this new contract
and demonstrates more simplified and more flexible use cases.

NEWT Fixes:

- All NEWT implementation's native code method names end with 0.

- GLWindow: don't issue the actual 'init'/'display' call to GLEventListeners
  in case the window is not visible.

- NEWT setSize/setPosition:
    if native-window
        call native-window action and let the attributes being set by
        the feedback call, which issues more action, ie RESIZE.
    else
        set the attributes directly, no feedback call/action is necessary.

X11 Fixes:

- X11GLContext MakeContextCurrent:
  Use MakeCurrent in case write and read drawable are equal,
  otherwise SEGV happens on ATI with heavy multithreading involved!
  Even XLockDisplay and XSync didn't help here ..

- X11GLXDrawableFactory shared resource:
  Removed the resource holder thread to simplify code,
  hence proper release is no more desired and it could become a cause for deadlock.

- Moved XInitThreads() from NEWT X11Window -> NativeWindow X11Util,
  since NativeWindow is loaded first (essential for XInitThreads())
  and it is the more basic lib.

- Made call to XInitThreads() conditional, ie it's spared if
  AWT could be used - which causes SEGV .. (AWT bug). See X11Util.java

JOGL Fixes:

- GLProfile.isAWTAvailable() -> NativeWindowFactory.isAWTAvailable()
- GLProfile.isAWTJOGLAvailable() -> GLProfile.isAWTAvailable()
