* src/extract.c (ARCHIVED_PERMSTATS): Add a comment saying that
S_IRWXG | S_IRWXO might be masked out.
(set_mode): Set the mode if some bits were masked out originally.
(set_stat): Don't chmod before chown, as that might temporarily
grant permissions that we don't want to grant. The chmod was
there only to work around broken hosts, so add a comment advising
users not to use those broken hosts instead.
(repair_delayed_set_stat, extract_dir):
Remember to mask out current umask before inverting permissions.
(extract_dir): If the owner might change, or if the mode has
special bits, create the directory 700 at first, but restore it later.

(extract_file, extract_node, extract_fifo): If the owner might
change, omit group and other bits at first, but restore them after
changing the owner.

(stat_to_env): Report full resolution in time stamps.
* configure.ac: Remove checks for struct stat.st_spare1, struct
stat.st_atim.tv_nsec, struct stat.st_atimespec.tv_nsec, struct

for minor device number.
(write_header_name, dump_hard_link, dump_file0):
Simplify test for old GNU format.

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.

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.
Fix error recovery: decrease `size' by `written', not
by `count', otherwise tar misses the next header
Do not diagnose write errror if to_command_option
is set, since the command may have exited prematurely.
It would be better to check for sigpipe, though.
(prepare_to_extract): Handle to_command_option
