The generic function stream-check-eof-no-hang
determines if the data source of the stream is at end of file, without hanging.
stream should be an instance of a subclass of buffered-stream.
result is :eof

otherwise.
There is a built-in method specialized on buffered-stream which returns :eof
in all cases.
