* src/sparse.c: Include <inttostr.h>.
(struct tar_sparse_file): offset and dumped_size are off_t, not
size_t. optab is now const *.
(dump_zeros): Return bool success flag, not off_t.
All callers changed.
Use a constant-zero buffer rather than clearing a buffer each time.
Don't mess up if write fails.
(dump_zeros, check_sparse_region):
Don't assume off_t is no wider than size_t.
(tar_sparse_init): Don't bother clearing a field that is already clear.
(zero_block_p): First arg is const *, not *.
(clear_block, SPARSES_INIT_COUNT): Remove.
(sparse_add_map): First arg is now struct start_stat_info *, not
struct tar_sparse_file *. All callers changed.
Use x2nrealloc to check for size_t overflow.
(parse_scan_file): Cache commonly-used parts of file.
Use an auto buffer, not a static one.
Don't bother clearing the buffer; not needed.
Don't bother clearing items that are already clear.
(oldgnu_optab, star_optab, pax_optab): Now const.

reading into it; just clear the parts that aren't read into.

(diff_buffer): Remove; now a local var.
(check_sparse_region): Don't bother clearing buffer before
reading into it. Don't assume off_t is promoted to long.

Use an auto status, not static.
* src/tar.h (struct tar_stat_info): had_trailing_slash is
now bool, not int.
* src/xheader.c (sparse_offset_coder, sparse_numbytes_coder):
Rewrite to avoid cast.
(sparse_offset_decoder, sparse_numbytes_decoder):
Diagnose excess entries rather than crashing.
Invalid header fields go undiagnosed.
Some valid time strings are ignored.
* NEWS: Better support for full-resolution time stamps.
The -v option now prints time stamps only to 1-minute resolution.
* gnulib.modules: Add utimens.
* lib/.cvsignore: Add imaxtostr.c, inttostr.c, inttostr.h,
offtostr.c, umaxtostr.c, utimens.c, utimens.h. Remove paxconvert.c.

* lib/paxconvert.c: Remove; superseded by umaxtostr.c.
* po/POTFILES.in: Remove lib/paxconvert.c. Add lib/xalloc-die.c,
lib/obstack.c.
* src/buffer.c (set_start_time, compute_duration, start_time):
Use gettime rather than rolling our own code.

(newer_ctime_option): Remove.
(timespec_lt): New function.
(OLDER_STAT_TIME): Use it.

(tartime): Time arg is now struct timespec. New bool arg.
All callers changed.
(code_ns_fraction): New decl.
(sys_stat_nanoseconds): Remove decl.
(get_stat_atime, get_stat_ctime, get_stat_mtime): New functions.
(set_stat_atime, set_stat_ctime, set_stat_mtime): New functions.
* src/compare.c: Include utimens.h rather than rolling our own.
(diff_dir, diff_file, diff_link, diff_symlink, diff_special):
Prototype.
(diff_dumpdir, diff_multivol): Prototype.
(diff_file): Support higher-resolution time stamps.
* src/create.c: Include utimens.h rather than rolling our own.
(MAX_OCTAL_VAL): New macro.
(tar_copy_str, string_to_chars): Don't bother to zero-fill;
the destination is already zeroed.
(string_to_chars): First arg is char const *.
(start_private_header): Use MINOR_TO_CHARS, not MAJOR_TO_CHARS,
for minor device number.
(write_header_name, dump_hard_link, dump_file0):
Simplify test for old GNU format.
(start_header): Put in placeholders for uid, etc., even when
using extended headers, for benefit of older "tar" implementations.
Don't assume uintmax_t is wider than 32 bits.
Output extended header for mtime if needed.
(dump_regular_finish, dump_file0):
Support extended time stamp resolution.
* src/extract.c: Include utimens.h rather than rolling our own.
(check_time): Support extended time stamp resolution.
* src/list.c: Include <inttostr.h>.
(tartime): Use umaxtostr rather than stringify_uintmax_t_backwards.
* src/xheader.c: Include <inttostr.h>.
Do not include <xstrtol.h>.
(strtoimax) [!HAVE_DECL_STRTOIMAX && !defined strtoimax]: New decl.
(strtoumax) [!HAVE_DECL_STRTOUMAX && !defined strtoumax]: New decl.
(BILLION, LOG10_BILLION): New constants.
(to_decimal): Remove; superseded by inttostr. All callers changed
to use umaxtostr.
(xheader_format_name): Don't assume pids and uintmax_t values
fit in 63 bytes (!) when printed.
(decode_record): Don't bother to check for ERANGE; an out of range
value must be treater than len_max anyway.
If the length is out of range, output it in the diagnostic.
(format_uintmax): Remove; all callers changed to use umaxtostr.
(xheader_print): Don't assume sizes can be printed in 99 bytes (!).
(out_of_range_header): New function.
(decode_time): Use it.
(code_time): Accept struct timespec, not time_t and unsigned long.
All callers changed. Size sbuf properly, and remove unnecessary check.
Don't assume time stamps can fit in 199 bytes.
Handle negative time stamps. Handle fractional time stamps
more consistently. Don't output unnecessary trailing zeros.
(decode_time): Yield struct timespec, not time_t and unsigned long.
All callers changed.
Handle negative time stamps. Truncate towards minus infinity
consistently. Improve overflow checks, and output a better
diagnostic on overflow.
(code_num): Don't assume uintmax_t can be printed in 99 bytes (!).
(decode_num): New function, for better diagnostics.
(atime_coder, atime_decoder, gid_decoder, ctime_coder):
(ctime_decoder, mtime_coder, mtime_decoder, size_decoder):
(uid_decoder, sparse_size_decoder, sparse_numblocks_decoder):
(sparse_offset_decoder, sparse_numbytes_decoder):
Use decode_num, etc., instead of xstrtoumax, etc.
* src/xheader.c (sparse_numblocks_decoder): Remove unchecked use
of `calloc'. Use xcalloc instead.
(decode_time, gid_decoder, size_decoder, uid_decoder):
(sparse_size_decoder, sparse_offset_decoder, sparse_numblocks_decoder):
Ensure that the result of calling xstrtoumax is no larger than
the maximum value for the target type. Upon any failure, exit with
a diagnostic.
(sparse_numblocks_decoder): Avoid buffer overrun/heap corruption:
use x2nrealloc, rather than `n *= 2' and xrealloc(p, n,....
(decode_time): Rewrite to accept time strings like
1119018481.000000000. Before, such strings were always ignored.
