eliminate some uses of bare pointers to octave_function objects * pt-classdef.h, pt-classdef.cc (tree_classdef::make_meta_class): Return octave_value instead of pointer to octave_function object. Change all uses. * cdef-class.h, cdef-class.cc (cdef_class::get_method_function, cdef_class::get_constructor_function): Return octave_value instead of pointer to octave_function object. Change all uses. * cdef-manager.h, cdef-manager.cc (classdef_manager::find_method_symbol, classdef_manager::find_package_symbol): Return octave_value instead of pointer to octave_function object. Change all uses. * parse.h, oct-parse.yy (base_parser::primary_fcn): Rename from primary_fcn_ptr and store octave_value instead of pointer to octave_function object. Change all uses.
