This patch constifies add_info and updates all the info commands. The bulk of this patch was written using a script; and then I did a manual pass to fix up the remaining compilation errors. I could not compile every changed file; in particular nto-procfs.c, gnu-nat.c, and darwin-nat-info.c; but I at least tried to check the correctness by inspection. gdb/ChangeLog 2017-11-07 Tom Tromey <tom@tromey.com> * frame.h (info_locals_command, info_args_command): Constify. * auto-load.h (auto_load_info_scripts): Constify. * inferior.h (registers_info): Constify. * copying.c: Rebuild. * copying.awk: Constify generated commands. * auto-load.c (auto_load_info_scripts) (info_auto_load_gdb_scripts): Constify. * cli/cli-decode.c (struct cmd_list_element): Take a cmd_const_cfunc_ftype. * command.h (add_info): Take a cmd_const_cfunc_ftype. * tui/tui-win.c (tui_all_windows_info): Constify. * python/py-auto-load.c (info_auto_load_python_scripts): Constify. * cli/cli-cmds.c (show_command): Remove non-const overload. * tracepoint.c (info_tvariables_command, info_scope_command): Constify.
