    [SPARK-15473][SQL] CSV data source fails to write and read back empty data

    ## What changes were proposed in this pull request?
    
    This PR adds the support for writing and reading back empty data in CSV data source.
    
     Also, this PR lets the CSV data source write schema in the header when `header` option
is `true` even if given data is empty. Currently, this is not writing header in this case.
    
    Currently, Parquet and JSON can write and read back empty dataset but CSV does not support.
    
    ## How was this patch tested?
    
    Unit tests in `CSVSuite.scala`.
