If USE_LOCAL_ALLOCATORS, allocate some Lisp objects on stack.

* lisp.h (local_cons, local_list1, local_list2, local_list3)
[USE_LOCAL_ALLOCATORS]: New macros.
[!USE_LOCAL_ALLOCATORS]: Fall back to regular functions.
(build_local_string): Avoid argument name expansion clash with
make_local_string.
* alloc.c (toplevel)
[USE_LOCAL_ALLOCATORS && GC_MARK_STACK != GC_MAKE_GCPROS_NOOPS]:
Preprocessor guard to avoid impossible configuration.
* charset.c (Ffind_charset_region, Ffind_charset_string):
Use make_local_vector.
* lread.c (read1, substitute_object_recurse): Use scoped_cons.
* textprop.c (Fput_text_property, Fadd_face_text_property):
Use scoped_list2.
(copy_text_properties): Use local_cons and local_list3.
* chartab.c (uniprop_table):
* data.c (wrong_choice, wrong_range):
* doc.c (get_doc_string):
* editfns.c (format2):
* fileio.c (Fexpand_file_name, auto_save_error):
* fns.c (Fyes_or_no_p):
* font.c (font_parse_xlfd, font_parse_family_registry, font_add_log):
* fontset.c (Fset_fontset_font):
* keyboard.c (echo_add_key, echo_dash, parse_menu_item)
(read_char_minibuf_menu_prompt):
* keymap.c (silly_event_symbol_error, describe_vector):
* menu.c (single_menu_item):
* minibuf.c (Fread_buffer):
* process.c (status_message, Fformat_network_address)
(server_accept_connection): Use make_local_string and
build_local_string.  Prefer compound literals where appropriate.
