Add unified support for GL_ARB_debug_output and GL_AMD_debug_output.

If GL_ARB_debug_output is not available, but GL_AMD_debug_output exist, fallback to the latter,
offering generic aliased methods translating the delta (AMD category <-> ARB source/type).

Generic aliased methods reside in GLContext*

Enable/Disable via GLContext and GLAutoDrawable.

To enable the GLDebugOutput feature GLContext.enableGLDebugMessage(true)
or GLContext.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG)
shall be called _before_ context creation via GLContext.makeCurrent()!

In case GLAutoDrawable is being used,
GLAutoDrawable.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG)
shall be issued before context creation via GLContext.makeCurrent()!.

After context creation, the GLDebugOutput feature may be enabled or disabled
at any time using this method.

Verify both unit tests for usability.
