Summary: minidom setNamedItem unlinks replaced attributes

Initial Comment:
Older minidoms used to prematurely unlink attributes that 
were being replaced in setAttributeNode[NS] calls, 
resulting in Attr objects whose ownerDocument was 
None.

This was fixed by having removeAttributeNode writing to 
ownerDocument after unlinking, but the same problem 
remains in NamedNodeMap.setNamedItem[NS].

Suggest fix to add after line 589 of minidom.py:

  old.ownerDocument = self.ownerDocument

(Again, setNamedItem and setNamedItemNS ought to be 
different calls, as they may replace different nodes.)
