    Fortran: Add user defined error messages for UDTIO.

    The defines IOMSG_LEN and MSGLEN were redundant so these are combined
    into IOMSG_LEN as defined in io.h.

    The remainder of the patch adds checks for when a user defined
    derived type IO procedure sets the IOSTAT or IOMSG variables
    independent of the librrary defined I/O messages.

            * io/io.h (IOMSG_LEN): Moved to here.
