umka/umka_os.c
Ivan Baravy f7942d2eb3 New tool lfbviewx, new shell commands, fix bug in process_info(-1).
* lfbviewx: LFB viewer for X. Reads framebuffer of umka_os and displays
  the picture in X window.
* New shell commands: dump_appdata, dump_taskdata, mouse_move.
* Bug with process_info is because SLOT_BASE in umka_os is not aligned
  on 0x10000. Mitigated with a macro.
