Fix a bug in file size limitation code.
This fixes a bug in stapio, which checks written data size and switches new file when it exceeds a limit. The problem is that written-data-size counter ignores the first written-data size when switching files. So, actual file size always exceeds the limit. This changes stapio to initialize written-data-size counter with the size of the data which will be written in new file.
