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

File:

• uspace/srv/hid/output/proto/vt100.c (moved) (moved from uspace/srv/hid/fb/proto/vt100.c ) (8 diffs)
