GLContext adds FBO availability to profile mapping; Fix GL[Auto]Drawable/GLContext re-association (switch) incl. unit test.

- GLContext adds FBO availability to profile mapping

- GLContext added 'GLDrawable setGLDrawable(GLDrawable readWrite, boolean setWriteOnly)'
  allowing to set the write GLDrawable. This method enables switching context/drawable.

Fix GL[Auto]Drawable/GLContext re-association (switch) incl. unit test
  Commit eed8508ae1132e5f45f788e9cb3f3d5a1050ac70 impl. of GLAutoDrawable's setContext(..)
  enabled proper setting of the GLAutoDrawable context incl. updating the context's drawables.
  Test covers:
  - remove/set (GLContext, GLEventListener) of GL[Auto]Drawable
  - switch (GLContext, GLEventListener) of 2 GLAutoDrawables
