JOGL: Unify library loading (impl and binding), incl. lookup ; GLAutoDrawable: dispose() calls only with created context.

- Using the EGL approach of DynamicLookupHelper,
  now generalized in abstract GLDynamicLookupHelper,
  DesktopGLDynamicLookupHelper and EGLGLDynamicLookupHelper.
  The implementation of these are self contained.

  - Sharing common code.
  - Unifying implementation and binding loading,
    as well as the function lookup within the impl libs.

- Removed DRIHack, since its no more required
  due to the new DesktopGLDynamicLookupHelper.

- Removed compile time link to GL and GLU libs

- Removed redundant library OS functions from X11/WGL
  bindings, GlueGen's common code is being used now.

- GLAutoDrawable: dispose() calls only with created context.
  This cleans up stack traces in case of eventual bugs,
  where context creation is not successful.
