        PR fortran/25829 28655
        * gfortran.map: Add new symbol, _gfortran_st_wait.
        * libgfortran.h (st_paramter_common): Add new I/O parameters.
        * open.c (st_option decimal_opt[], st_option encoding_opt[],
        st_option round_opt[], st_option sign_opt[], st_option async_opt[]):
New
        parameter option arrays. (edit_modes): Add checks for new parameters.
        (new_unit): Likewise. (st_open): Likewise.
        * list_read.c (CASE_SEPERATORS): Add ';' as a valid separator.
        (eat_separator): Handle deimal comma. (read_logical): Fix whitespace.
        (parse_real): Handle decimal comma. (read_real): Handle decimal comma.
        * read.c (read_a): Use decimal status flag to allow comma in place of a
        decimal point. (read_f): Allow comma as acceptable character in float.
        According to decimal flag, substitute a period for a comma.
        (read_x): If decimal status flag is comma, disable the read_comma flag,
        not allowing comma as a delimiter, an extension otherwise.
        * io.h: (unit_decimal, unit_encoding, unit_round, unit_sign,
        unit_async): New enumerators. Add all new I/O parameters.
        * unix.c (unix_stream, int_stream): Add io_mode asychronous I/O
control.
        (move_pos_offset, fd_alloc_w_at): Fix some whitespace.
        (fd_sfree): Use new enumerator. (fd_read): Likewise.
        (fd_write): Likewise. (fd_close): Fix whitespace.
        (fd_open): Use new enumertors. (tempfile, regular_file,
        open_external): Fix whitespace. (output_stream, error_stream): Set
        method. (stream_offset): Fix whitespace.
        * transfer.c: (st_option decimal_opt[], sign_opt[], blank_opt[]): New
        option arrays.  (formatted_transfer_scalar): Set sf_read_comma flag
        based on new decimal_status flag. (data_transfer_init): Initialize new
        parameters. Add checks for decimal, sign, and blank. (st_wait): New
stub.
        * format.c: (format_lex): Add format specifiers DP, DC, and D.
        (parse_format_list): Parse the new specifiers.
        * write.c (write_decimal): Use new sign enumerators to set the sign.
        (write_complex): Handle decimal comma and semi-colon separator.
        (nml_write_obj): Likewise.
        * write_float.def: Revise sign enumerators. (calculate_sign): Use new
        sign enumerators. (output_float): Likewise. Use new decimal_status flag
        to set the decimal character to a point or a comma.
