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.
