Sync the minizip code from upstream

[cen1]

Pull in the latest minizip code

Observation: quite a few changes from the code that is currently in the repo.

1. Diff against the old clean version to strictly document local changed and additions. Already pretty good in some places.
2. Apply the changes to the new code
3. Think of a way to avoid this work for future sync
