restores the 2.1 ability of Tools/scripts/ndiff.py to start producing
output before the entire comparison is complete.

easy for 2.2 new-style classes, but trickier for classic classes, and
different approaches are needed "depending".  The function will allow
later code to treat all flavors of classes uniformly.

somewhere inside a line, use ndiff so that intraline difference marking
can point out what changed within a line.  I don't remember diff-style
abbreviations either (haven't used it since '94, except to produce
patches), so say the rest in English too.

Lib/test/output/test_StringIO is no longer necessary.

Also, added a test of the iterator protocol that's just been added to
StringIO's and cStringIO's.

expected output, this fixes that.

the first difference, let the test run till completion, then gather
all the output and compare it to the expected output using difflib.

XXX Still to do: produce diff output that only shows the sections that
differ; currently it produces ndiff-style output because that's the
easiest to produce with difflib, but this becomes a liability when the
output is voluminous and there are only a few differences.

classes to __getattribute__, to make it crystal-clear that it doesn't
have the same semantics as overriding __getattr__ on classic classes.

This is a halfway checkin -- I'll proceed to add a __getattr__ hook
that works the way it works in classic classes.

please let me know and we'll figure out how to fix the test.)

docstrings (using file.closed and file.name as examples).

no backwards compatibility to worry about, so I just pushed the
'closure' struct member to the back -- it's never used in the current
code base (I may eliminate it, but that's more work because the getter
and setter signatures would have to change.)

As examples, I added actual docstrings to the getset attributes of a
few types: file.closed, xxsubtype.spamdict.state.

allows using the tests with unittest.py as a script.  The tests will
still run when run as a script themselves.

compatibility, this required all places where an array of "struct
memberlist" structures was declared that is referenced from a type's
tp_members slot to change the type of the structure to PyMemberDef;
"struct memberlist" is now only used by old code that still calls
PyMember_Get/Set.  The code in PyObject_GenericGetAttr/SetAttr now
calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef
argument.

As examples, I added actual docstrings to the attributes of a few
types: file, complex, instance method, super, and xxsubtype.spamlist.

Also converted the symtable to new style getattr.
