IGNORE_FAILED_READ_OPTION, INDEX_FILE_OPTION, NO_OVERWRITE_DIR_OPTION,
NUMERIC_OWNER_OPTION, RECURSIVE_UNLINK_OPTION, REMOVE_FILES_OPTION,
SHOW_OMITTED_DIRS_OPTION, TOTALS_OPTION): New constants.

New arg FD. All uses changed.
Do not read more than INT_MAX bytes at once,
since it breaks on some brain damaged Tru64 hosts.
Do not mix int and size_t pointers. Divide size by two
when retrying instead of subtracting 1024; for speed.
(main): Use gettext to translate (C), not print_copyright.
(hash_string_hasher): Renamed from hash_avoided_name.
(hash_string_compare): Renamed from compare_avoided_anames.

Truncate file at end.
(extract_archive): Use safer_name_suffix rather than rolling our own.
Use fill_in_sparse_array rather than rolling our own.
Strip trailing slashes more effectively.
Check for unsafe names.
All callers changed.
(start_header): Clear devmajor and devminor fields, too.
(finish_header): New arg block_ordinal.
(init_sparsearray): Now extern. Set sp_array_size to
SPARSES_IN_OLDGNU_HEADER if it is zero.
