To clarify:

 - usr.bin/unzip was hooked up to the build in head in December 2009,
   long before 9 was branched, so 9.0 shipped with it.

 - stable/8 has the same libarchive as stable/9.

 - I MFCed all outstanding changes yesterday, so stable/8 has the same
   unzip as stable/9.  The only functional changes were a missing error
   check and support for reading the zipfile from stdin.

 - I also MFCed the Makefile change yesterday, so stable/8 now installs
   usr.bin/unzip.
