mmaped and add new reserved field. * locale/programs/locarchive.c (RESERVE_MMAP_SIZE): Define. (create_archive): Reserve address space and then map file into it. (open_archive): Likewise. (file_data_available_p): New function. (compare_from_file): New function. (close_archive): Adjust to member name changes. (add_locale): Before comparing locale data, check it is mapped. Otherwise fall back to reading from the file.
