eliminate static wrapper functions in gh_manager class This is a large but straightforward change to eliminate the remains of the singleton pattern that was used for the gh_manager class. All static functions in the gh_manager class that previously used the "instance" function to access the gh_manager object stored in the global interpreter object and then called the corresponding "do_" functions have been eliminated. The "do_" prefix has been removed from the normal member functions and all uses of the static functions (calls of the form gh_manager::X) have been replaced with a call to the member function. The gh_manager object is accessed through the interpreter object and there is a new __get_gh_manager__ convenience function defined in the intepreter-private.cc file. Additionally, instead of using the gh_manager::auto_lock class, we access the mutex variable associated with the gh_manager object and pass it to the octave::autolock constructor to manage scoped locks for the gh_manager class. The following interpreter functions are now "methods" and require the interpreter as the first argument: F__calc_dimensions__, F__fltk_check__, F__get__, F__get_frame__, F__go_axes__, F__go_delete__, F__go_execute_callback__, F__go_figure__, F__go_figure_handles__, F__go_handles__, F__go_hggroup__, F__go_image__, F__go_light__, F__go_line__, F__go_patch__, F__go_post_callback__, F__go_surface__, F__go_text__, F__go_uibuttongroup__, F__go_uicontextmenu__, F__go_uicontrol__, F__go_uimenu__, F__go_uipanel__, F__go_uipushtool__, F__go_uitable__, F__go_uitoggletool__, F__go_uitoolbar__, F__image_pixel_size__, F__show_figure__, F__shutdown_qt__, F__update_normals__, F__zoom__, Faddlistener, Faddproperty, Fdellistener, Fdrawnow, Fget, Fishghandle, Fkbhit, Fpause, Freset, Fset, and Fwaitfor.
