Using off_t, at least, in DiskAdaptor layer is problematic because torrent can contain under 2GiB files but total sum of those files may exceed 2GiB limit, which makes off_t overflow in 32 bit system without large file support. So we use int64_t in API. We'll check the file length before download so that it does not exceed max off_t.
