gfs_pio_seek - reposition a stream

       The gfs_pio_seek() function sets the file position indicator for the file gf. The new position, measured
       in bytes, is obtained by adding offset bytes to the position specified by whence. If whence is set to
       GFARM_SEEK_SET, GFARM_SEEK_CUR, or GFARM_SEEK_END, the offset is relative to the start of the file, the
       current position indicator, or end-of-file, respectively. When result is not NULL, the new position
       returns to the address pointed by result.
