Bochs/bochs/bochs.h
Bryce Denney 26385f2866 - I've added lots of comments in siminterface.h, and tried to clean up 
the terminology a bit.  In particular, the term "gui" has started
  to mean different things in different contexts, so I've defined
  some more specific names for the parts of the user interface, and
  updated comments and some variable names to reflect it.  See
  siminterface.h for a more complete description of all of these.

    VGAW: VGA display window and toolbar buttons, the traditional Bochs
      display which is ported to X, win32, MacOS X, etc.  Implemented
      in gui/gui.* and platform dependent gui/*.cc files.
    CI: configuration interface that lets the user change settings such
      as floppy disk image, ne2k settings, log options.  The CI consists
      of two parts: configuration user interface (CUI) which does the
      actual rendering to the screen and handles key/mouse/menu events,
      and the siminterface object.
    CUI: configuration user interface.  This handles the user interactions
      that allow the user to configure Bochs.  To actually change any
      values it talks to the siminterface object.  One implementation of
      the CUI is the text-mode menus in gui/control.cc.  Another
      implementation is (will be) the wxWindows menus and dialogs in
      gui/wxmain.cc.
    siminterface: the glue between the CUI and the simulation code,
      accessible throughout the code by the global variable
        bx_simulator_interface_c *SIM;
      Among other things, siminterface methods allow the simulator to ask the
      CUI to display things or ask for user input, and allows the CUI
      to query and modify variables in the simulation code.


    GUI: Literally, "graphical user interface".  Until the configuration menus
      and wxWindows came along, everyone understood that "gui" referred to the
      VGA display window and the toolbar buttons because that's all there
      was.  Now that we have the wxWindows code, which implements both the VGAW
      and the CUI, while all other platforms implement only the VGAW, it's not
      so clear.  So, I'm trying to use VGAW, CI, and CUI consistently since
      they are more specific.
    control panel: This has been used as another name for the configuration
      interface.  "control panel" is also somewhat unspecific and it sounds
      like it would be graphical with buttons and sliders, but our text-mode
      thing is not graphical at all.  I've replaced "control panel" with
      "configuration interface" wherever I could find it.  In configure script,
      the --disable-control-panel option is still supported, but it politely
      suggests that you use --disable-config-interface instead.
- clean up comments in siminterface,wx* code
- add comments and examples for bx_param_* and BxEvents
- remove some obsolete stuff: notify_*_args,
  bx_simulator_interface_c::[sg]et_enabled() methods
- in siminterface.cc, move a few bx_real_sim_c methods to where they belong,
  with the rest of the methods.  No changes to the actual methods.
- remove some DOS ^M's which crept in and confused my editor.
