(prepare_input_buffer): Renamed from prepare_record_buffer.
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.

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.

(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

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.
(decode_options): Use print_copyright, not copyright_symbol.
(OVERWRITE_DIR_OPTION): New constant.
(long_options, usage, decode_options): Add --overwrite-dir.
recent_long_link_blocks): New vars.
(read_and): Pass 0 to read_header.
(read_header): New arg RAW_EXTENDED_HEADERS. Store away extended headers
into new vars. Null-terminate incoming symbolic links.
(delay_set_stat): Initialize it to 0.
(set_mode): New arg current_stat_info. Use it (if nonnull) to avoid
taking an extra stat ourselves. All callers changed.
(set_stat): Likewise.
(apply_nonancestor_delayed_set_stat): New arg 'after_symlinks'.
If false, stop when encountering a struct whose 'after_symlinks' member is
true. Otherwise, go through all structures but check them more carefully.
All callers changed.
(extract_archive): When extracting a deferred symlink, if its parent
directory's status needs fixing, then mark the directory as needing
to be fixed after symlinks.
(extract_finish): Fix status of ordinary directories, then apply delayed
symlinks, then fix the status of directories that are ancestors
of delayed symlinks.
struct hack; this avoids wasted space in some cases.
(name_gather): Use strcpy, not memcpy.
for consistency with other code that does similar things.
(read_name_from_file, name_next, name_gather, add_hierarchy_to_namelist):
Avoid quadratic behavior when reallocating buffers.
Check for buffer size overflow.
(addname): Avoid unnecessary clearing of memory.
This fixes a bug reported by Jose Pedro Oliveira.
(dump_file): Use offsetof when computing sizes for
struct hack; this avoids wasted space in some cases.
name size allocation that caused core dumps.
From Jan.Djarv@mbox200.swipnet.se.
(extract_archive): Use strcpy, not memcpy,
for consistency with other code that does similar things.
NO_IGNORE_CASE_OPTION, NO_WILDCARDS_OPTION, NO_WILDCARDS_MATCH_SLASH_OPTION,
WILDCARDS_OPTION, WILDCARDS_MATCH_SLASH_OPTION): New enum values.
(long_options, usage, decode_options): Add support for --anchored,
--ignore-case, --no-anchored, --no-ignore-case, --no-wildcards,
--no-wildcards-match-slash, --recursion, --wildcards,
--wildcards-match-slash.
(decode_options): Implement the new way of interpreting exclude patterns.
(usage): --newer-mtime takes a DATE operand. DATE may be a file name.
(OPTION_STRING, decode_options): Add -I, -y. Currently these options
just print error messages suggesting alternatives.
(add_filtered_exclude): Remove.
However, check for error even for '-' or '+' case.
(print_header): Try parsing uids and gids as unsigned integers first,
and as a uid_t or gid_t only if that fails. This adds support for
listing positive uids and gids that are greater than UID_MAX and
GID_MAX.
Support hard links to symbolic links.
(struct delayed_symlink): Remove 'names' member, replacing it with
'sources' and 'target' member. All uses changed.
(struct string_list): New type.
(delayed_set_stat, extract_archive): Use offsetof when computing sizes
for struct hack; this avoids wasted space in some cases.
(extract_archive): Fix test for absolute pathnames and/or "..".
Use link_error to report errors for links.
Remove redundant trailing '/' at "really_dir", for all uses, not
just before invoking mkdir.
If overwriting old files, do not worry so much about existing directories.
Fix mode computation in the case where the directory exists.
(apply_delayed_symlinks): If we can't make a hard link to a symbolic
link, make a copy of the symbolic link.
(usage): Remove -I as an alias for -T>
(OPTION_STRING): Remove -I.
(decode_options): Dates that look like an absolute path name,
or that start with '.', are presumed to be file names whose
dates are taken.
Remove 'I' as an aliase for 'T'.
Update copyright.
> (relativize): New function, with much of old start_header's guts.
Handle filesystem prefixes.
(start_header): Use this new function.
(init_sparsearray): Don't bother to zero out the new array; it's not needed.
(deal_with_sparse): Fix array allocation bug.
(create_archive): Don't assume '/' is the only separator.
(dump_file): Likewise.
Don't worry about leading / in symlink targets.
(time): Remove decl; likewise.
(child_open_for_uncompress): Use new full_write semantics.
(flush_write): Use ISSLASH instead of testing for '/'.
(flush_read): Likewise.
