Bochs/bochs/gui/textconfig.cc
Volker Ruppert e5c68dd4ac Rewrite of the optional plugin control feature. 
- Now that we know about all available plugins at startup, the bx_list_c object
  "plugin_ctrl" contains a fixed number of bx_param_bool_c objects representing
  the requested status (1 = load). It is verified at simulation startup.
- The config interface creates two text lists (textconfig) or list boxes (win32,
  wx) from it to show the remaining available and the loaded plugins. Loading
  and unloading is performed immediately and plugins may install / uninstall
  options in other menus / dialogs.
- Modified the "non-plugin" code to make the optional plugin control work very
  similar in this mode.
