* In _GSocket_Get_Mac_Socket(), do not call CFSocketSetSocketFlags to turn
  off kCFSocketCloseOnInvalidate.  Furthermore,
  kCFSocketAutomaticallyReenableWriteCallback wasn't part of default flags
  but had been erroneously included here.
* Call CFSocketInvalidate() from _GSocket_Diable_Events instead of from
  _GSocket_GUI_Destroy_Socket.  GSocket calls this from GSocket_close
  and so in combination with the above change and the most recent change
  to gsocket.c the CFSocket should now be invalidated and closed for all
  cases and not just planned shutdown.
