Count MANY function args more reliably

* alloc.c (Fgc_status, purecopy, unbind_to, garbage_collect_1):
* buffer.c (Fbuffer_list, Fkill_buffer):
* callint.c (read_file_name, Fcall_interactively):
* charset.c (Fset_charset_priority, syms_of_charset):
* chartab.c (uniprop_encode_value_numeric):
* coding.c (syms_of_coding):
* composite.c (syms_of_composite):
* data.c (wrong_range):
* dbusbind.c (syms_of_dbusbind):
* dired.c (file_attributes):
* editfns.c (Fdecode_time, update_buffer_properties, format2):
* eval.c (run_hook_with_args_2, apply1, call1, call2, call3)
(call4, call5, call6, call7):
* fileio.c (Finsert_file_contents, choose_write_coding_system)
(Fcar_less_than_car, build_annotations, auto_save_error):
* filelock.c (get_boot_time):
* fns.c (internal_equal, nconc2, Fyes_or_no_p, Fwidget_apply):
(maybe_resize_hash_table, secure_hash):
* font.c (font_style_to_value, font_open_by_name, Flist_fonts):
* fontset.c (fontset_add, Fset_fontset_font):
* ftfont.c (ftfont_lookup_cache):
* gtkutil.c (xg_get_font):
* insdel.c (signal_before_change, signal_after_change):
* keymap.c (append_key):
* lread.c (load_warn_old_style_backquotes, Fload, init_lread):
* minibuf.c (Fread_buffer):
* print.c (print_preprocess):
* process.c (Fformat_network_address, Fmake_network_process)
(server_accept_connection):
* sound.c (Fplay_sound_internal):
* term.c (Fsuspend_tty, Fresume_tty):
* window.c (window_list):
* xdisp.c (run_redisplay_end_trigger_hook, add_to_log)
(message_with_string):
* xfaces.c (Fx_list_fonts):
* xfont.c (syms_of_xfont):
* xselect.c (x_handle_selection_request)
(x_handle_selection_clear, x_clear_frame_selections)
(x_clipboard_manager_error_1):
Prefer CALLMANY and CALLN to counting args by hand.
* doc.c (reread_doc_file): Remove unused code.
* fns.c (concat2, concat3): Redo to avoid need for local-var vector.
(cmpfn_user_defined, hashfn_user_defined, Fmaphash):
Prefer call1 and call2 to Ffuncall.
* keyboard.c (safe_run_hook_funcall, safe_run_hooks):
Use struct literal rather than a local var, for simplicity.
* keymap.c (where_is_internal): Use NULL rather than a pointer
to unused args.
* lisp.h (CALLMANY, CALLN): New macros.
* sound.c (Fplay_sound_internal): Coalesce duplicate code.
