* 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.

option is undocumented because it does nothing. It does nothing
because bsdtar never needs it. It is accepted because gnutar does
sometimes need it and many scripts use it.

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)
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.
--exclude='pattern'.
I should have added this a long time ago, since it's so useful for testing.
In particular, it allows me to select a few entries from a troublesome
archive so that I can easily focus my debugging efforts:
bsdtar -czf new.tgz --include='*foo*' @old.tgz
While I'm here, add a couple of extra sanity-checks to
the argument parsing (reject -j -z, for instance) and
update the docs a bit.
Requested by: most everyone ;-)
