This patch replaces the gzstream zlib wrapper with the iostream3 wrapper provided as part of zlib contributions. The main reason for the switch is to avoid including LGPL in the default gem5 build. iostream3 is provided under a more permissive license: The code is provided "as is", with the permission to use, copy, modify, distribute and sell it for any purpose without fee.
