This removes the broken wine version of atexit and onexit. It keeps only dllonexit, which is implemented properly. The previous __call_atexit is moved to where the mingw onexit/atexit code is and adjusts it to work with the existing code. A call to __call_atexit is added in __tmainCRTStartup after the main function was called.
