This adds "offset_limit", which will contain the limit specified by --max-pack-size, "written_list", the actual list of objects written to the current pack, and "nr_written", the number of objects in written_list. "prev_pack" is added to struct object_entry to indicate when an object has already been written but to a previous pack. The fields in object_entry are re-arranged & shrunk to save memory.
