the collected string: it can contain embedded nulls

functions.

functions. Handle GNU.sparse.map and GNU.dumpdir variables.

variable has been explicitely deleted, use GNU.sparse.offset/
GNU.sparse.numbytes variables.

this allows to correctly detect renamed files.
(read_directory_file,write_directory_file)

This affects behavior only on older hosts or file systems
that have lower-resolution time stamps.

that we don't need, to save space. All uses changed.

(create_placeholder_file, extract_link, apply_delayed_links):
Use full time stamp resolution.
(check_time): Use code_timespec rather than rolling our own code.
(set_stat, delay_set_stat): Arg now points to tar_stat_info to
avoid losing time information. All callers changed.

separately, for benefit of hosts with lower resolution.
* src/update.c (update_archive): Use full time stamp resolution.
* src/xheader.c (code_time): Use new code_timespec function
to simplify code.
(atime_coder, atime_decoder, ctime_coder, ctime_decoder):
(mtime_coder, mtime_decoder): Use full time stamp resolution.
Report time stamps to full resolution in environment.
Report memory allocation failures rather than ignoring them.

(oct_to_env, str_to_env, chr_to_env): Report memory allocation failures.
(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
stat.st_atimensec, as gnulib now does this for us.
Similarly for LIB_CLOCK_GETTIME.
