Add sparse_file_repsarse, which splits chunks in an existing sparse file such that the maximum size of a chunk, plus a header and footer, is smaller than the given size. This will allow multiple smaller sparse files to result in the same data as a large sparse file. Change-Id: I177abdb958a23d5afd394ff265c5b0c6a3ff22fa
