[Patches] Change to reference-dump procedure at shutdown

This patch only affects debug builds with Py_TRACE_REFS defined.  This =
is the default for debug builds on Windows.

At shutdown, Python offers to dump the remaining references.  This =
upsets a few programs, such as debug COM servers, or any program that =
uses 'sys.executable' to launch a child-process.  The process never =
terminates, as it is waiting to find out if you want the references =

Further, simply starting and closing the Python interpreter on Windows =
results in over 2000 references - its unlikely people want to print them =
that often :-)

The patch below only offers to dump the references if the environment =
variable PYTHONDUMPREFS is set.  Otherwise, it still prints the number =
of references, but immediately terminates.

If this patch is acceptable and it is felt this variable should be =
documented, let me know, and I will try and hunt down all the relevant =
places - but IMO, anyone who really needs these references dumped is =
likely to see this code :-)
