[Bug #1414697] Change docstring of set/frozenset types to specify that the contents are unique.  Raymond, please feel free to edit or revert.

test_compiler now passes again.

docstrings correctly as it did in Python 2.4.

Regenerated Modules/_ctypes/libffi/configure with autoconf 2.59.

with PEP 302.  This was fixed by adding an ``imp.NullImporter`` type that is
used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
excessive filesystem operations during imports.

Cosmetic changes to the code so that the #ifdef _UNICODE block
doesn't mess emacs code formatting.

The reduces the test_uuid failures, but there's still another method failing.

concept, and that different ways of trying to find "the
hardware address" may return different results.  Certainly
true on both of my Windows boxes, and in different ways
(see whining on python-dev).

  methods now allow their database parameter to be None as the
  sleepycat API allows.

Also adds an appropriate test case for DBEnv.dbrename and dbremove.

We didn't notice these before because test_defaultdict didn't
actually do anything before Georg fixed that earlier today.
Neal's next refleak run then showed test_defaultdict leaking
9 references on each run.  That's repaired by this checkin.

Note that this has only been tested for VS 2003 since that's all I have.

lost that tests are sorted by name before being run.  ``DocTestFinder``
has been changed to sort the list of tests it returns.

inspect.py, and pydoc.py.  Specifically, this allows for querying the type of
an object against these built-in C types and more importantly, for getting
their docstrings printed in the interactive interpreter's help() function.

This patch includes a new built-in module called _types which provides
definitions of getset and member descriptors for use by the types.py module.
These types are exposed as types.GetSetDescriptorType and
types.MemberDescriptorType.  Query functions are provided as
inspect.isgetsetdescriptor() and inspect.ismemberdescriptor().  The
implementations of these are robust enough to work with Python implementations
other than CPython, which may not have these fundamental types.

The patch also includes documentation and test suite updates.

I commit these changes now under these guiding principles:

1. Silence is assent.  The release manager has not said "no", and of the few
   people that cared enough to respond to the thread, the worst vote was "0".

2. It's easier to ask for forgiveness than permission.

3. It's so dang easy to revert stuff in svn, that you could view this as a
   forcing function. :)

Windows build patches will follow.
