 // Reads tabular data from CSV (Comma Separated Values) format as defined in RFC
 // 4180, with the following limitations/relaxations:
 //   * The input should be UTF-8 encoded. No code points should be escaped.
 //   * The first line must be a header that contains the column names.
 //   * Records may be separated by either LF or CRLF sequences. Each CRLF will
 //     be converted to LF characters inside quotes.
 //   * Inconsistent number of fields within records is handled gracefully. Extra
 //     fields are ignored. Missing fields will have no corresponding key-value
 //     pair in the record's ColumnNameToValueMap.
 //   * Repeated columns of the same name are not supported (the last value will
 //     be preserved).
 //
 // The CSV representation of the data will be read from |csv|. The first line of
 // the file should be a header to extract |column_names| from. From each
 // subsequent line, the extracted values are put into a map mapping column names
 // to the value of the corresponding field, and inserted into |records|. Both
 // |column_names| and |records| will be overwritten. Returns false if parsing
 // failed due to a syntax error.
