Fix classpaths to work with Java 7's javah

Java 7's javah requires all referenced classes to be classpath,
even if they're just method parameters and never instantiated.
Java 6's version of javah didn't require this.

Proper classpath for all javah commands, using 'rootrel.build'

JAWTWindow.getLocationOnScreen(): Add proper JAWT lockSurface() ; X11Util: use System.err ; TestParenting02AWT: use GearsES2

JAWTWindow.getLocationOnScreen()
  - Add proper JAWT lockSurface()
  - Turns out that the parent location query of a NEWT child
    to an [J]AWT window didn't lock the window

ShaderState Usage/Test: Add setShaderState(GL) for pre-use attachment to the GL context ; GLArrayDataClient-GLSL: Check if ShaderState is attached.

ShaderState Usage/Test: Add setShaderState(GL) for pre-use attachment to the GL context
  - test cases utilize ShaderState before useProgram() was invoked,
    hence we need an API entry to attach the ShaderState explictly

GLArrayDataClient-GLSL: Check if ShaderState is attached.
  - catch error case of non bound ShaderState to GL context

Tests: Comment GLProfile.initSingleton(false), which is redundant / implicit.

NEWT Window/WindowImpl: Add generics - addChild()/removeChild() return boolean, see Collection::add/remove

Complete commit cb4e73183103c13d8bcf7c7667e1b9ea181e1f5f (sorry)

Fix NEWT regression due to fix of bug 502, commit 9ed513e9a9616f6028084df4c650c8caf31ea49d

In case of exessive destroy/create (the NEWT reparenting test cases),
some dpyEDT events are slipping through the event dispatcher.

This fix uses issues more XSync on both Display connection in case of 'requestFocus'
and 'closeWindow'.

'requestFocus' also uses the dpyEDT to issue the XSetInputFocus(..), since it's EDT related.

SWT/AWT Test: Run AWT destruction on AWT-EDT, issue shell.close() before shell.dispose()

This fixes the _XSend X11 error on GLX commands using AMD driver .. proper cause unknown,
but probably a race or condition or threading issue (Display usage by diff threads).

Use GlueGen's setenv-build-jogl scripts from commit 4a75b64107e157ff1db3991cf89bf8d856ddc0e6

TestAWTTextRendererUseVertexArrayBug464: Run AWT destruction on AWT-EDT

This fixes the _XSend X11 error on GLX commands using AMD driver .. proper cause unknown,
but probably a race or condition or threading issue (Display usage by diff threads).

TestGLDebug*: Remove Thread.dumpStack() ..
