Message:

cherrypick GUI implementation (originally by Petr Koupy), with several major changes

  • for character-oriented devices a new output server and output protocol was created based on the original fb server
  • DDF visualizer drivers are pixel-oriented only
  • console and compositor can coexist in the same build
  • terminal widget is self-sufficient, no strange console nesting is needed
