On Windows, ctypes does no longer check the stack before and after 

calling a foreign function.  This allows to use the unmodified libffi
library.

Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...).  Other files are used in the
cross-platform _ctypes/libffi directory.

The purpose is to hack the libffi sources so that they can be compiled
with MSVC, and to extend them so that they have the features I need
for ctypes.
I retrieved the libffi sources from the gcc cvs repository on
2004-01-27. Then I did 'configure' in a 'build' subdirectory on a x86
linux system, and copied the files I found useful.
