Py_Initialize(): Now that standard exceptions are builtin, we don't need two phase init or fini of the builtin module. Change the call of _PyBuiltin_Init_1() to _PyBuiltin_Init(). Add a call to init_exceptions(). Py_Finalize(): Don't call _PyBuiltin_Fini_1(). Instead call fini_exceptions() but move this to before the thread state is cleared.
