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.

Backport of r67106 from the py3k branch
* crashes on memory allocation failure found with failmalloc
* memory leaks found with valgrind
* compiler warnings in opt mode which would lead to invalid memory reads
* problem using wrong name in decimal module reported by pychecker
Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

done
At least some of these fixes should probably be backported to 2.5.
First chapter of the Python 3.0 io framework back port: _fileio
The next step depends on a working bytearray type which itself depends on a backport of the nwe buffer API.
