[classlib][pack200] Another opportunity for buffering

                 Key: HARMONY-5913
                 URL: https://issues.apache.org/jira/browse/HARMONY-5913
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
    Affects Versions: 5.0M6
         Environment: Pack200 HEAD
            Reporter: Andrew Cornwall
         Attachments: main.patch

I found one more opportunity for buffering to improve the speed of the pack200 Archive API
by about 8% when unpacking  from one file to another.

This won't affect the performance of the Pack200.Unpacker API, but will serve as a useful
example of why it's important to pass a buffered JarOutputStream in rather than a simple JarOutputStream
on a FileOutputStream.
