  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
  stay (updated from _ctypes/libffi/...).  Other files are used in the
  cross-platform _ctypes/libffi directory.

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

Patch by George Sakkis

#7643: Unicode codepoints VT (0x0B) and FF (0x0C) are linebreaks according to Unicode Standard Annex #14.

Addition of delta keyword argument to unittest.TestCase.assertAlmostEquals and assertNotAlmostEquals

This allows the comparison of objects by specifying a maximum difference; this includes the comparing of non-numeric objects that don't support rounding.

Rename the unittest test_suite function to not clash with a test module name (unittest.test.test_suite is now unambiguous).

A fix for running unittest tests on platforms without the audioop module (e.g. jython and IronPython)

reads and writes are always retried by OpenSSL itself.

(this is a followup to issue #3890)
