Switch back to the native Pack200 implementation for the moment

This isn't ideal as it's deprecated. However, while Apache Harmony's
unpack200 implementation seems fine, its pack200 implementation doesn't
work with the client and produces invalid output.

I've fixed some of the easy to fix bugs, but tracking down any remaining
bugs will be difficult - it'll involve tracing through the native
unpack200 code.

When Pack200 is removed from the JDK, hopefully someone will take up the
mantle of maintaining it outside of the JDK. If that doesn't happen,
we'll have to consider writing our own Pack200 implementation,
extracting OpenJDK's implementation out of the tree or fixing the bugs
in Apache Harmony.
