Changes

Fix macosx compilation

Fix macosx NEWT warnings

Minor cleanup: strings, unused vars, ..

DEBUG strings w/ thread name

nativewindow.TraceLock -> nativewindow.debug.ToolkitLock.TraceLock

Sync Xmisc (DummyWindow) with NEWT's creation

test scripts: awt and non-awt usage

NativeWindow: Provide 'setX11ErrorHandler(boolean onoff)'

JOGL DrawableFactory/AWT: Only use AWT factory if AWT is enabled

.. and a little cleanup in the X11 SharedResourceRunner

JOGL GLContextImpl: Trigger ProcAddressTable mapping via 'setGLFunctionAvailability' call while scanning all available context.

.. also reorder context scanning from low -> high

JOGL/X11: Fix context scanning, misc simplifications ..

Fix context scanning
---------------------
Ie on 3.0 NVidia systems, trying to create a 4.1 context leads
to a BadAlloc X11 error.
A prev patch disabled the X11 error handler, to reduce sideeffects.
In case AWT is not being used, the BadAlloc isn't catched and the JVM freezes
within the native function call.

Decorating context scanning with NativeWindow's 'setX11ErrorHandler' solves this issue.

Simplifications
-----------------
X11: always try a direct context. If this is not possible due to the display connection,
an indirect is being used anyways. Hence 'createContext(boolean direct)' -> 'createImpl()'.

X11/WGL: Simplify the context creation logic a bit.

NEWT: ScreenModeUtil fix, misc changes

ScreenModeUtil fix:
- return 'null' for an empty list, check if list is null or empty.
- remove 'validate'

Window: TIMEOUT_NATIVEWINDOW 500 -> 1000 ms

NEWT Window Lifecycle / ScreenMode:

Lifecycle.reparentActionPre()/reparentActionPost() -> pauseRenderingAction()/resumeRenderingAction()
for a more generic use, ie reparenting and screen mode change.

ScreenMode change: No more visibility/fullscreen changes, no more locking,
                   just pause/resume animation.

X11 ScreenMode set: move from thread/wait to simple polling over time (timeout)
