This almost entirely replaces how pydoc pumps out class docs, but only
in text mode (like help(whatever) from a Python shell), not in GUI mode.

A class C's attrs are now grouped by the class in which they're defined,
attrs defined by C first, then inherited attrs grouped by alphabetic order
of the defining classes' names.

Within each of those groups, the attrs are subgrouped according to whether
they're plain methods, class methods, static methods, properties, or data.
Note that pydoc never dumped class data attrs before.  If a class data
attr is implemented via a data descriptor, the data docstring (if any)
is also displayed (e.g., file.softspace).

Within a subgroup, the attrs are listed alphabetically.

This is a friggin' mess, and there are bound to be glitches.  Please
beat on it and complain!  Here are three glitches:

1. __new__ gets classifed as 'data', for some reason.  This will
   have to get fixed in inspect.py, but since the latter is already
   looking for any clue that something is a method, pydoc will
   almost certainly not know what to do with it when its classification
   changes.

2. properties are special-cased to death.  Unlike any other kind of
   function or method, they don't have a __name__ attr, so none of
   pydoc's usual code can deal with them.  Worse, the getter and
   setter and del'er methods associated with a property don't appear
   to be discoverable from Python, so there's really nothing I can
   think of to do here beyond just listing their names.

   Note that a property can't be given a docstring, either (or at least
   I've been unable to sneak one in) -- perhaps the property()
   constructor could take an optional doc argument?

3. In a nested-scopes world, pydoc still doesn't know anything about
   nesting, so e.g. classes nested in functions are effectively invisible.

mimelib and email, but most of the implementations are shared (except
where cool Py2.2 stuff like generators are used).

Added signatures for some new PyType_*() functions.

point out, pydoc doesn't tell you where class attributes were defined,
gets several new 2.2 features wrong, and isn't aware of some new features
checked in on Thursday <wink>.  pydoc is hampered in part because
inspect.py has the same limitations.  Alas, I can't think of a way to
fix this within the current architecture of inspect/pydoc:  it's simply
not possible in 2.2 to figure out everything needed just from examining
the object you get back from class.attr.  You also need the class
context, and the method resolution order, and tests against various things
that simply didn't exist before.  OTOH, knowledge of how to do that is
getting quite complex, so doesn't belong in pydoc.

classify_class_attrs takes a different approach, analyzing all
the class attrs "at once", and returning the most interesting stuff for
each, all in one gulp.  pydoc needs to be reworked to use this for
classes (instead of the current "filter dir(class) umpteen times against
assorted predicates" approach).

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.

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

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.
