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.

When a node number disagrees, keep track of all sources & the
node numbers they reported, and stick all that in the error message.

Changed all callers to supply a non-empty "source" argument; made
the "source" argument non-optional.

On my box, test_uuid still fails, but with the less confusing output:

AssertionError: different sources disagree on node:
    from source 'getnode1', node was 00038a000015
    from source 'getnode2', node was 00038a000015
    from source 'ipconfig', node was 001111b2b7bf

Only the last one appears to be correct; e.g.,

C:\Code\python\PCbuild>getmac

Physical Address    Transport Name

I can't find anything on my box with MAC 00-03-8a-00-00-15, and am
not clear on where that comes from.

Fix the DllGetClassObject and DllCanUnloadNow so that they forward the
call to the comtypes.server.inprocserver module.

The latter was never documented, never used by published code, and
didn't work anyway, so I think it does not deserve a NEWS entry (but I
might be wrong).

by regrtest.py.

We really need a simpler testing framework.

No functional change.  Add comment and assert to describe why there cannot be overflow which was reported by Klocwork.  Discussed on python-dev

Reported by Klocwork # 74.

to kill a cygwin instance.  build\\python.exe was matching a normal windows
instance.  Prefix that with a \\ to ensure build is a directory and not
PCbuild.  As discussed on python-dev.

In general, C doesn't define anything about what happens when
an operation on a signed integral type overflows, and PyOS_strtol()
did several formally undefined things of that nature on signed
longs.  Some version of gcc apparently tries to exploit that now,
and PyOS_strtol() could fail to detect overflow then.

Tried to repair all that, although it seems at least as likely to me
that we'll get screwed by bad platform definitions for LONG_MIN
and/or LONG_MAX now.  For that reason, I don't recommend backporting
this.

Note that I have no box on which this makes a lick of difference --
can't really test it, except to note that it didn't break anything
on my boxes.

Silent change:  PyOS_strtol() used to return the hard-coded 0x7fffffff
in case of overflow.  Now it returns LONG_MAX.  They're the same only on
32-bit boxes (although C doesn't guarantee that either ...).

just ImportError.  This allows documentation tools to better skip unimportable
packages.

[Bug #1471938] Fix build problem on Solaris 8 by conditionalizing the use of mvwgetnstr(); it was conditionalized a few lines below.  Fix from Paul Eggert.  I also tried out the STRICT_SYSV_CURSES case and am therefore removing the 'untested' comment.
