Integrated bdist_wininst into PCBuild9 directory

The detection now works on Unix with Makefile, Makefile with VPATH and on Windows.

Fixed get_config_h_filename for Windows. Without the patch it can't find the pyconfig.h file inside a build tree.
Added several small unit tests for sysconfig.

The new msvc9compiler module supports VS 2005 and VS 2008. I've also fixed build_ext to support PCbuild8 and PCbuild9 and backported my fix for xxmodule.c from py3k. The old code msvccompiler is still in place in case somebody likes to build an extension with VS 2003 or earlier.
I've also updated the cygwin compiler module for VS 2005 and VS 2008. It works with VS 2005 but I'm unable to test it with VS 2008. We have to wait for a new version of cygwin.

and smtpd.py scripts that are installed by setup.py. That way, they
work when only "make altinstall" is used.

As discussed on distutils-sig: Allows the generated installer name on
64bit Windows platforms to be different than the name generated for
32bit Windows platforms.

Move an import in mworkscompiler so that this module can be imported on
any platform.  Hopefully this works on all platforms.

even if package_dir is empty.

This needs to be backported.  I'm too tired tonight.  It would be great
if someone backports this if the buildbots are ok with it.  Otherwise,
I will try to get to it tomorrow.

(as opposed to the command line) will now write file names ending in
".cpp" too.

If MSVCCompiler.initialize() was called multiple times, the path
would get duplicated.  On Windows, this is a problem because the
path is limited to 4k.  There's no benefit in adding a path multiple
times, so prevent that from occuring.  We also normalize the path
before checking for duplicates so things like /a and /a/ won't both
be stored.

installed to build extensions. This patch makes distutils emit a warning when
the compiler should use an SDK but that SDK is not installed, hopefully reducing
some confusion.

universal build of python on OSX 10.3 to ensure that those flags can be used
to compile code (the universal build uses compiler flags that aren't supported
on 10.3). This patches gives the same treatment to CFLAGS, PY_CFLAGS and
BLDSHARED.
