        PR libgfortran/20257
        * io/io.h: Add prototypes for get_internal_unit and free_internal_unit.
        * io/unit.c (get_internal_unit): Initialize unit number, not zero.
        (free_internal_unit): New function to consolidate freeing memory.
        (get_unit): Initialize internal_unit_desc to NULL when unit is
        external.
        * io/unix.c (mem_close): Check for not NULL before freeing memory.
        * io/transfer.c (read_block): Reset bytes_left and skip error if unit
        is preconnected and default record length is reached.
        (read_block_direct): Ditto.
        (write_block): Ditto.
        (write_buf): Ditto.
        (data_transfer_init): Only flush if not internal unit.
        (finalize_transfer): Ditto and delete code to free memory used by
        internal units.
        (st_read_done): Use new function - free_internal_unit.
        (st_write_done): Use new function - free_internal unit.
