* 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.

* 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.
forthcoming. This commit also has a number of style(9) fixes and
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().

particular, acl support is no longer enabled on FreeBSD 4, acl support
should be correctly enabled on Linux, dirent.d_namlen should be
correctly detected on platforms that support it.
Thanks to: Greg Lewis, Juergen Lock, and Jaakko Heinonen
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.
switches to support selecting files by time of modification.
Special thanks to: Steven M. Bellovin, Rich $alz, and Jim Berets,
authors of the public-domain getdate.y date-parsing code.
In particular:
-W excl=text
fails because "excl" is a prefix of both "exclude" and "exclude-from". But,
-W exclude=text
is okay because it matches "exclude" exactly.

synonym for --format. Update the man page to reflect this. While
I'm here, change the man page to document "tar" rather than "bsdtar,"
update some comments about -l compatibility and fix a few grammar nits.
For -l, upset everyone by breaking it. Specifically, -l now produces
a lengthy error message that suggests --check-links (POSIX -l) or
--one-file-system (GNU -l) instead. However, if POSIXLY_CORRECT is set,
use the POSIX interpretation.
For -o, please everyone by making it work both ways:
* -xo uses POSIX behavior
* -co uses "almost GNU" behavior (as close as we can get until
libarchive implements a true V7 tar format)
of course, but I make an effort to accomodate GNU tar scripts that
use -o with -c (with a meaning that totally contradicts SUSv2) by
only issuing a benign warning message in that case.
* Don't change the umask; the library now ignores the umask if
you set EXTRACT_PERM
* Set the EXTRACT_ACL and EXTRACT_FFLAGS bits (used to be
controlled by EXTRACT_PERM).
* 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.
This requires some non-trivial surgery to the options parsing.
While here, let people who only have getopt() access long options
through the -W longopt=value convention.
