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().
use -b 2048 (1MiB block size). Setting the limit to 8192 should
allow some room for growth while still helping people who mistakenly
put in byte counts here instead of block counts.
* Add xz and lzma compression options
* Rename --format-options to simply --options
* Add --same-owner for GNU tar compat
* Add -lmd and -lcrypto to fix link
* Documentation
Translate getdate.y into C for portability. Make the get_date()
function easier to test as well:
* Have it accept a time_t "now" to use as a reference so that test
code can verify relative time specifications against known starting
points.
* Set up default date after parsing the string so that we
can use the specified timezone (if any) instead of the local
default. Otherwise, local DST makes it almost impossible to
reliably test time specifications such as "sunday UTC"
This replaces the getopt()/getopt_long() wrapper, the old-style
argument rewriter and the associated configuration glue with a more
straightforward custom command parser. In particular, this ensures
that bsdtar will have consistent option parsing on every platform,
regardless of whether the platform supports getopt_long().

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.
running 'tar ""' would print 'No memory' instead of the correct error

files if the existing file is newer than the archive entry).
Currently if any files are ignored, bsdtar will exit with a non-zero
exit status; this is likely to change in the future, but requires some
API changes in libarchive.

* --format can be used with -r or -u
* -o is a synonym for --format=ustar when used with -c, -r, or -u
Also, fix the erroneous sanity check that suppressed --format with -r or -u.
GNU tar changed -l to match SUSv2 a couple of years ago,
so bsdtar no longer needs to pander to this particular GNUism.

MFC after: 7 days
* prototypes for optarg/optind on platforms that don't already have them
* Disambiguate version number macros
* Remove unnecessary PACKAGE_NAME macro
* Hook for forthcoming bsdtar test suite
* Sync version number up with the portable distribution
* 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.
MFC after: 15 days
* 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
attribute support and implemented both the machine-independent portion
and the Linux-specific portion.
(I'm not using GPL, but I still think there are good
ideas in the GNU projects. ;-) Among other things,
this should make it easier for clients of bsdtar to
recognize it automatically:
bsdtar --version | grep bsdtar
set up before it is called, so move the progname initialization before
the first possible call to bsdtar_warnc().
