Fixed issue #4233.
Changed semantic of _fileio.FileIO's close() method on file objects with closefd=False.
The file descriptor is still kept open but the file object behaves like a closed file.
The FileIO object also got a new readonly attribute closefd.

the bytearray, returned the same bytearray instead of a copy.
