bugs #126161 and 123634).
The solution doesn't use the unicode-escape encoding; that has other
problems (it seems not 100% reversible). Rather, it transforms the
input Unicode object slightly before encoding it using
raw-unicode-escape, so that the decoding will reconstruct the original
string: backslash and newline characters are translated into their
\uXXXX counterparts.
This is backwards incompatible for strings containing backslashes, but
for some of those strings, the pickling was already broken.
Note that SF bug #123634 complains specifically that cPickle fails to
unpickle the pickle for u'' (the empty Unicode string) correctly.
This was an off-by-one error in load_unicode().
XXX Ugliness: in order to do the modified raw-unicode-escape, I've
cut-and-pasted a copy of PyUnicode_EncodeRawUnicodeEscape() into this
file that also encodes '\\' and '\n'. It might be nice to migrate
this into the Unicode implementation and give this encoding a new name
('half-raw-unicode-escape'? 'pickle-unicode-escape'?); that would help
pickle.py too. But right now I can't be bothered with the necessary
infrastructural changes.

obsolete!).
Fix a bug in ftpwrapper.retrfile() where somehow ftplib.error_perm was
assumed to be a string. (The fix applies str().)
Also break some long lines and change the output from test() slightly.
Make Node inherit from xml.dom.Node to pick up the NodeType values
defined by the W3C recommendation.
When raising AttributeError, be sure to provide the name of the attribute
that does not exist.
Node.normalize(): Make sure we do not allow an empty text node to survive
as the first child; update the sibling links properly.
_getElementsByTagNameNSHelper(): Make recursive calls using the right
number of parameters.
Attr.__setattr__(): Be sure to update name and nodeName at the same time
since they are synonyms for this node type.
AttributeList: Renamed to NamedNodeMap (AttributeList maintained as an
alias). Compute the length attribute dynamically to allow
the underlying structures to mutate.
AttributeList.item(): Call .keys() on the dictionary rather than using
self.keys() for performance.
AttributeList.setNamedItem(), .setNamedItemNS():
Added methods.
Text.splitText():
Added method.
DocumentType:
Added implementation class.
DOMImplementation:
Added implementation class.
Document.appendChild(): Do not allow a second document element to be added.
Document.documentElement: Find this dynamically, so that one can be
removed and another added.
Document.unlink(): Clear the doctype attribute.
_get_StringIO(): Only use the StringIO module; cStringIO does not support
Unicode.
objects; uses minidom if one is not provided to the constructor.
parse(): Pick up the default_bufsize default value dynamically so that
the value in the module may be (meaningfully) changed at runtime.
This (partially) closes patch #102477.
