(hash_string_hasher): Renamed from hash_avoided_name.
(hash_string_compare): Renamed from compare_avoided_anames.
(hash_string_insert, hash_string_lookup): New functions.
(add_avoided_name, is_avoided_name): Use them.
(safer_name_suffix): New function.
(contains_dot_dot): Moved here from misc.c. Now returns bool, not int.
(read_header): Strip trailing slashes, setting current_trailing_slash.
(tartime): Avoid int overflow when printing year (!).
(print_header): New arg specifing block ordinal. All uses changed.
Print link as 'h' type. Give labels for long links and names.
(check_time): Warn about implausibly old time stamps.
(set_stat): Use utimbuf, not stat_info.
(preprare_to_extract): New arg DIRECTORY.
(fill_in_sparse_array): Moved here from compare.c.
(extract_sparse_file): Now returns off_t, giving size left.
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.
(dump_file): Keep link table as a hash.
Do not count "file changed as we read it" as a failure.
(child_open_for_compress): Do not increase size to BLOCKSIZE.
(open_archive): Open index file name.
Strip trailng slahes from file names.
(flush_write): Set size to 0 if not saving names.
(flush_write, flush_read): Use safer_name_suffix rather than
inline code.
indefinitely; keep it only for the next file. This fixes a bug
introduced in 1.13.24, and remove the need for some static variables.
Set recent_long_name and recent_long_link to zero if there were no
long links; this avoids a violation of ANSI C rules for pointers in
delete.c.
EILSEQ, because BSD/OS 4.1 defines EILSEQ in <wchar.h>, which requires
<time.h>. Define a replacement EILSEQ to be ENOENT, not EINVAL, since
callers may want to distinguish EINVAL and EILSEQ.
