Remove the field privatemodes from struct __aiocb_private and the

related code from aio_read() and aio_write().  This field was
intended, but never used, to allow a mythical user-level library to
make an aio_read() or aio_write() behave like an ordinary read() or
write(), i.e., a blocking I/O operation.
