All unicode functions uses PyObject* except PyUnicode_AsWideChar(). Fix the
prototype for the new function PyUnicode_AsWideCharString().

 * Convert unicode to wide character string before creating the PyCapsule
   object
 * Catch integer overflow
 * Avoid useless memset()
 * Prepare the support of surrogates

Issue 8781: On systems a signed 4-byte wchar_t and a 4-byte Py_UNICODE, use memcpy to convert between the two (as already done when wchar_t is unsigned)

  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.
