Proposed patch for python 2.[56] to enable elementtree

[Brian de Alwis <briandealwis%gmail.com@localhost>]

Attached is a patch to simply install the _elementtree module Pythons  
2.5 and 2.6 and deprecate the textproc/py-elementtree package.

The ElementTree package, and its C-optimized module called  
cElementTree, provides support for processing XML files.  We have a  
corresponding textproc/py-elementtree package, which curiously doesn't  
install the optimized cElementTree module.

Python 2.5 and 2.6 now include ElementTree and cElementTree.   
Unfortunately the in-tree variants have had some renaming from the  
external distributions: the classes have been moved from elementtree.*  
to xml.etree.*, and the cElementTree module has been renamed to  
_elementtree.

Unfortunately because of the renaming, simply installing the py- 
elementtree is not sufficient to enable the functionality.  Since the  
py-elementtree package must support lang/python2[34], we can't just  
change py-elementtree to follow the EXTRACT_ELEMENTS approach used in  
py-expat.  We could add a py-celementtree with a CONFLICTS on py- 
elementtree.

But since _elementtree doesn't have any other dependencies, I propose  
we simply change the lang/python2[56] packages to install the in-tree  
_elementtree module, and mark the py-elementtree package as being for  
Python 2.4 and 2.3.  The patch also adds _sqlite3 to the disabled  
modules in python26; this seems to have been missed.

Brian.
