PR libgfortran/25828
* libgfortran.h: Rename GFC_LARGE_IO_INT to GFC_IO_INT.
* io/file_pos.c (st_backspace): Ignore if access=STREAM.
(st_rewind): Handle case of access=STREAM.
* io/open.c (access_opt): Add STREAM_ACCESS.
(edit_modes): Set current_record to zero only if not STREAM.
(new_unit): Initialize maxrec, recl, and last_record for STREAM.
* io/read.c (read_x): Advance file position for STREAM.
* io/io.h (enum unit_access): Align IOPARM flags with frontend.
Add ACCESS_STREAM. Add prototype for is_stream_io () function.
Use GFC_IO_INT.
* io/inquire.c (inquire_via_unit): Add text for access = "STREAM".
* io/unit.c (is_stream_io): New function to return true if access =
STREAM.
* io/transfer.c (file_mode): Add modes for unformatted stream and
formatted stream. (current_mode): Return appropriate file mode based
on access flags.
(read_block): Handle formatted stream reads.
(read_block_direct): Handle unformatted stream reads.
(write_block): Handle formatted stream writes.
(write_buf): Handle unformatted stream writes.
(unformatted_read): Fix up, use temporary for size.
(pre_position): Position file for STREAM access.
(data_transfer_init): Initialize for stream access, skip irrelevent
error checks.
(next_record_r),(next_record_w), and (next_record): Do nothing for
stream I/O.
(finalize_transfer): Flush when all done if stream I/O.
