Move archive_compressor_gzip_free and archive_compressor_gzip_options
after archive_write_add_filter_gzip. This is preparation to use an
external program gzip if zlib is not available.
Parse a command line instead of using
archive_write_add_filter_programl,
archive_write_add_filter_programv,
archive_read_support_filter_programl,
archive_read_support_filter_programv,
archive_read_support_filter_programl_signature and
archive_read_support_filter_programv_signature.
And so remove those functions, which I recently added.
archive_read_support_filter_lrzip and archive_write_add_filter_lrzip
should return ARCHIVE_WARN instead of ARCHIVE_OK since those filters
always use an external program, lrzip(1) and other filters do so
if they use an external program instead of implemented code with
the library. It is clear that returning ARCHIVE_WARN means the filter
uses an external program.
Apply __attribute__((deprecated)) to archive_read_open_file,
archive_write_open_file, archive_position_compressed,
archive_position_uncompressed, archive_compression_name and
archive_compression.
Revert part of d1be20168 because gunzip is still used in
test_read_filter_program and test_read_filter_program_signature,
which cannot give arguments to the program.
Fix a cause of segmentation fault in case of creating a child
process failed. It occured when archive_write_close() was called
after an opening filter process failed.
Remove unnecessary build condition for a use of
__archive_create_child(). It has worked well on both POSIX
system and non-POSIX system since libarchive 2.7.0.
Fix test_option_older_than failure on linux.
- Use pax format in test_option_older_than and test_option_newer_than
to make sure the nano second of a file time is recorded.
Add --older,--older-than,--older-mtime and --older-mtime-than to bsdtar to
enable only including files and directories older than specified date or file.
Fix a bug that Clang Static Analyzer claimed it is potential insecure
implementation-specific behavior in call 'vfork' and recommended the
use of posix_spawn instead of vfork.
Apply *_CLOEXEC flags to system calls which can be used with
to avoid file descriptor leaks to the child process.
- Pass O_CLOEXEC to open(2) system call if it is defined.
- Use fcntl(2) and F_DUPFD_CLOEXEC instead of dup(2)
if F_DUPFD_CLOEXEC is defined.
- Set FD_CLOEXEC with fcntl(2) if a file descriptor does not have.

Fix signed integer overflow in safe_fprintf()
The following "overflow" check in safe_fprintf() invokes undefined
behavior (signed integer overflow), which is incorrect. Clang will
optimize it away.
int old_length = fmtbuff_length;
fmtbuff_length += fmtbuff_length / 4;
if (old_length > fmtbuff_length) { ... }
The check is in the form:
x > x + x / 4.
As per the C standard, the check is equivalent to:
0 > x / 4,
since x + x / 4 is assumed to not overflow (otherwise undefined).
An earlier check ensures x >= 8192, so this check is always false,
and Clang doesn't emit code for it.
This patch uses unsigned integers to avoid undefined behavior.

Implement function used to seek within data blocks.
This only implements seeking fully for uncompressed RAR files. Seeking is not
implemented for compressed RAR files and for the other formats (ZIP, TAR, etc.).

Refactored common code into a single function
The tar_atol8() and tar_atol10() functions were essentially
identical. The code has been refactored to a common function
with tar_atol8() and tar_atol10() calling the commont function
with the radix instead duplicating the code.
The logic was also changed slightly to prevent a pointer
dereference when a zero length character array is passed to
the conversion routine.

Add tighter checks to avoid reading past end of buffer
The string to base 8/10 conversion routines could read past the
counted end of the buffer if the string is correctly formated.
The number of characters is now checked and decremented for every
character that is consumed for processing.
Minor improvement in the mtree bidder.
- During checking NetBSD mtree -D format, if the first character of
the last filed in an entry line is '/', fail the test bidding mtree
format.
