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.

* PyCObject_AsVoidPtr() can now open capsules.  This addresses
  most of the remaining backwards-compatibility concerns about
  the conversion of Python 2.7 from CObjects to capsules.
* CObjects were marked Pending Deprecation.
* Documentation about this pending deprecation was added to
  cobject.h.
* The capsule source files were added to the legacy PC build
  processes.

  Work in progress.  2 tests fail on x86/win32 because the stack
  checking code in ffi_call_win32 is not yet implemented.

  Remove most files from _ctypes/libffi_msvc, only two include files

  On Windows, ctypes does no longer check the stack before and after
  calling a foreign function.
  This allows to use the unmodified libffi library.
