Modifications for Zip64 support

Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )

For more info read MiniZip_info.txt
13
Oct-2009 - Mathias Svensson - Remove old C style function prototypes
14
Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives
15
Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions.
16
Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data
17
It is used when recreting zip archive with RAW when deleting items from a zip.
18
ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed.
19
Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required)
20
Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer
