Bug 1033: Guarantee atomicity of high-level GLAutoDrawable operations, avoiding race conditions.

GLAutoDrawable (API CHANGE) allowing atomic operations:
  - Add class API-doc chapter about 'GLAutoDrawable Locking'

  - Add method invoke(..) API-doc description about throwing IllegalStateException in case of a detected deadlock situation ahead
    (Note: Implemented in GLDrawableHelper.invoke(..) for all implementations)

  - Add new methods for proper multithread handling:
    - public RecursiveLock getUpstreamLock();
    - public boolean isThreadGLCapable();

+++

GLEventListenerState/GLDrawableUtil:

  - Perform operation in a atomic fashion,
    i.e. lock GLAutoDrawable during whole operations:
      - GLDrawableUtil.swapGLContext(..)
      - GLDrawableUtil.swapGLContextAndAllGLEventListener(..)
      - GLEventListenerState.moveFrom(..)
      - GLEventListenerState.moveTo(..)

  - ReshapeGLEventListener:
    - Moved from GLEventListenerState.ReshapeGLEventListener -> GLDrawableUtil.ReshapeGLEventListener
    - Takes 'displayAfterReshape' case into account.

javax.media.opengl.Threading Clarifications:
  - Public 'enum Mode', i.e. Threading.Mode

  - Public getMode()

  - Clarified 'isOpenGLThread()':
    - Take 'singleThreaded' into account directly,
      i.e. always return 'true' if singleThreaded == false
