Store builtins in cell variables to speed-up the common path,
reducing the chance of a lock needing to block at all.

Call _wfopen() on Windows, or fopen() otherwise. Return the new file object on
success, or NULL if the file cannot be open or (if PyErr_Occurred()) on unicode
error.

  Try to turn some buildbots green by allowing test_multiprocessing to
  pass even if it hits the sys.exc_clear code in the threading module, and
  improve the test coverage by making the ctypes dependencies a bit more
  granular (two of the cited ctypes objects don't exist on my system)

Use stat() or _wstat() depending on the OS.

It's a ParseTuple converter: decode bytes objects to unicode using
PyUnicode_DecodeFSDefaultAndSize(); str objects are output as-is.

 * Don't specify surrogateescape error handler in the comments nor the
   documentation, but PyUnicode_DecodeFSDefaultAndSize() and
   PyUnicode_EncodeFSDefault() because these functions use strict error handler
   for the mbcs encoding (on Windows).
 * Remove PyUnicode_FSConverter() comment in unicodeobject.c to avoid
   inconsistency with unicodeobject.h.

 * Use _Py_wchar2char() in _wstat() and _Py_wfopen()
 * Document _Py_char2wchar()
