7-Zip / Bzip2

[Freddie Cash]

Compression algorithms are something that should be handled via an
extendle library.  And the front-end apps (gzip, bzip2, 7z, etc)
should just use that library to do the heavy lifting.

Instead of pulling in another app, consider pulling in libarchive and
friends from FreeBSD 6+, and then adding 7z support to that.

Then you can remove compress, gzip, gunzip, bzip2, bunzip2, 7z, etc,
and just put in stub programs that call the library functions.
