[issue10841] binary stdio

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

New patch setting O_BINARY mode using _setmode() (on Windows) to stdin, stdout, stderr, but also to all FileIO() objects.

The patch on Py_Main() is still needed because Python may use sys.stderr when it is still a stdprinter object, before the final TextIOWrapper object is created (before the io module is loaded).

I don't know the effect of _setmode(stderr, O_BINARY) on calls to fputs(stderr, ...) in Py_FatalError().

I would appreciate a review of parser_translate_newline.patch.
