expunge the xmlcore changes:

  41667, 41668 - initial switch to xmlcore
  47044        - mention of xmlcore in What's New
  50687        - mention of xmlcore in the library reference

re-apply xmlcore changes to xml:
  41674        - line ending changes (re-applied manually), directory props
  41677        - add cElementTree wrapper
  41678        - PSF licensing for etree
  41812        - whitespace normalization
  42724        - fix svn:eol-style settings
  43681, 43682 - remove Python version-compatibility cruft from minidom
  46773        - fix encoding of \r\n\t in attr values in saxutils
  47269        - added XMLParser alias for cElementTree compatibility

additional tests were added in Lib/test/test_sax.py that failed with
the xmlcore changes; these relate to SF bugs #1511497, #1513611

+# by a simple module that indirected imports to the "xmlcore" package.

-parsers -- Python wrappers for XML parsers (currently only supports Expat).
-
-sax -- The Simple API for XML, developed by XML-Dev, led by David
-       Megginson and ported to Python by Lars Marius Garshol.  This
-       supports the SAX 2 API.
