report the compression ratio as 0% instead of displaying
nonsense triggered by numeric overflow. This is common
when dealing with uncompressed files when the I/O blocking
causes there to be small transient differences in the
accounting.

isolate common code used by tar and cpio (and useful to other
libarchive clients). The functions here are prefixed with
"lafe" (libarchive front-end) to indicate their use.
is sufficiently different that it was simpler to just put separate
reporting functions into read.c and write.c rather than try to have
a single all-purpose reporting function.
Switch to a custom function for converting int64_t to a string; in
the portable version, this saves a lot of configuration headaches
trying to decipher the platform printf().
I would like to provide a way to preview the effects of pathname edits,
but pattern selection has to happen against the unedited path, so it
seems that we have to show people the unedited path to help in
designing selection patterns.
In addition to a number of bug fixes and minor changes:
* --numeric-owner (ignore user/group names on create and extract)
* -S (sparsify files on extraction)
* -s (regex filename substitutions)
* Use new libarchive 'linkify' to get correct hardlink handling for
both old and new cpio formats
* Rework 'copy' test to be insensitive to readdir() filename ordering
Most of the credit for this work goes to Joerg Sonnenberger, who
has been duplicating features from NetBSD's 'pax' program.
handling to bsdtar. When writing archives (including copying via the
@archive directive) a line is output to stderr indicating what is being
done (adding or copying), the path, and how far through the file we are;
extracting currently does not report progress within each file, but
this is likely to happen eventually.

(This does a couple of things that the standard library's strmode()
doesn't; it proved useful in bsdcpio as well, so I pushed it down
into libarchive.)
* Implement --use-compress-program using new libarchive feature.
* Minor portability improvement by adjusting casts used to
print out uids, gids, and device numbers.
Thanks to: Joerg Sonnenberger for the --use-compress-program implementation.

occur on the write side of extracting a file to ARCHIVE_WARN errors
when returning them from archive_read_extract.
In bsdtar: Use the return code from archive_read_data_into_fd and
archive_read_extract to determine whether we should continue trying to
extract an archive after one of the entries fails.
This commit makes extracting a truncated tarball complain once about
the archive being truncated, instead of complaining twice (once when
trying to extract an entry, and once when trying to seek to the next
entry).

* New test scripts exercise some basic functionality
* Most header inclusions are now protected (portability)
* read.c now relies on security checks in libarchive instead
of trying to do its own (optimization)
* -p now enabled by default for root, add --no-same-permissions
to disable it
* Comments, minor style fixes.

minor corrections so the code works better with the build system being
used for non-FreeBSD builds.
Many thanks to: Jaakko Heinonen, who proposed a mechanism for extended

extraction and creation. While I'm here, fix a bug reported by Garrett
Wollman: when stripping the leading '/' from the path "/", don't produce
an entry with an empty name; produce "." instead.
* Add --null option (sort #defines here)
* Add process_lines function to util.c that reads newline-terminated
or null-terminated lines (with self-sizing buffers, etc) and iteratively
invokes a provided function. Use this to dramatically simplify:
-T handling for -c, --exclude-from-file, and --include-from-file.
* Add -T handling to -x (via include_from_file)
Hopefully, this will fix the openoffice port and a couple of
others that rely on -T and --null.
an existing symlink (as might happen if you extract an archive twice).
Also, if we remove the offending link, then we've removed the problem
and can safely go forward with the extraction.
Pointed out by: print/adobe-cmaps port (whose distfile has
duplicate entries for the same symlinks)
Thanks to: Kris Kennaway (for using ports as a testbed for bsdtar)
* Move format/compression reporting to end of output, since
we don't always know the input format until then.
* Set bsdtar exit value to 1 if any file could not be restored.
* Generate gtar-style warning when stripping leading '/' characters.
* Warn when removing symlinks.
directory, then a file with that symlink as a prefix can drop a file
outside of the current directory, which can be a security hole.
Plug this hole by refusing to extract files if a prefix of the
pathname is a symlink. The -P option disables this check.
