Complete LOCK_SURFACE_CHANGED ; Introduce NativeVisualID (Daisy chaining *GraphicsConfiguration) ; ...

NativeVisualID: New interface for Capabilities implementations,
  allowing retrieval of the native 'visual id'.
  Impl. by WGL, X11 and EGL.

JAWTWindow.lockSurface()
  - Detect surfaceHandle change an return LOCK_SURFACE_CHANGED (see: LOCK_SURFACE_CHANGED)

EGLDrawable:
  - Impl. updateHandle() (see: LOCK_SURFACE_CHANGED)

  - use NativeVisualID for EGLGraphicsConfiguration selection to respect a native 'visual id'

EGLContext.createContextImpl: Use NIO for attributes

EGLDisplayUtil: Enhance eglGetDisplay w/ DEBUG code and NativeSurface / EGL_DEFAULT_DISPLAY variation

EGL, XGL, WGL GraphicsConfiguration:
   - Don't set ALPHA_SIZE and STENCIL_SIZE if not requested in attribute list
     for context creation.
   - toString() shows proper identification, eg.: egl, x11, win32 ..

EGLGraphicsConfigurationFactory:
  Daisy chain GraphicsConfigurationFactory for native device type (currently only X11).
  This allows choosing the EGLGraphicsConfiguration and hence native visual id based on EGL
  when invoked via the factory model (generic).
  In case EGLGraphicsConfigurationFactory is not suitable or doesn't produce a native visual id,
  it falls back the the original one.

X11AWTGraphicsConfigurationFactory and X11Window:
  Use generic NativeVisualID which allows EGLGraphicsConfiguration implicit.

*GraphicsConfiguration's DEBUG flag is pushed up to DefaultGraphicsConfiguration

LOCK_SURFACE_CHANGED:
    - commit 006e9fe402a0a47b45fd2c4af51296aef895e8b5
    - commit a0177c8a1048683e5d43f4712f8f9e37091d4e85

Impact:
  - Fixes EGL/GLES (wrapper/native) usage on X11, proper Xvisual selection w/ EGL
  - Fixes EGL/GLES (wrapper/native) usage on Windows, ANGLE works w/ NEWT and forced ES2
