Python no longer fails at startup with a fatal error if a command
line argument contains an invalid Unicode character.

The Py_DecodeLocale() function now escapes byte sequences which would
be decoded as Unicode characters outside the [U+0000; U+10ffff]
range.

Use MAX_UNICODE constant in unicodeobject.c.
