util: added global sliding memory manager

pack: now using the global sliding memory manager. The current implementation uses assumes that packs are small enough to fit into memory right away, where the window size will be about 1 GB, as it never calls use_window() to assure the required offset actually exists. It will need to change to set the window appropriately.
