local functions in classdef files (bug #41723) * symtab.h, symtab.cc (symbol_table::fcn_info::fcn_info_rep::xfind): Also handle file-local functions (symbol_table::fcn_info::fcn_info_rep::x_builtin_find): Likewise. (symbol_table::fcn_info::fcn_info_rep::dump): Display info about local functions. (symbol_table::fcn_info::fcn_info_rep::local_functions): New map. (symbol_table::fcn_info::fcn_info_rep::fcn_info_rep): Initialize it. (symbol_table::fcn_info::fcn_info_rep::install_local_funciton): New function. (symbol_table::fcn_info::fcn_info_rep::clear): Clear local_functions map. (symbol_table::fcn_info::install_local_function): New function. (symbol_table::install_local_function): New function. * parse.h, oct-parse.in.yy (fcn_list, fcn_list1, opt_fcn_list): New non-terminals. Set parsing_local_functions after classdef is recognized. (file): Accept opt_fcn_list list after classdef object. (base_parser::parsing_local_functions): New data member. (base_parser::base_parser): Initialize it. (base_parser::finish_function): Handle local functions.
