CFRunLoopAddSource() and CFRunLoopRemoveSource() respectively. They
no longer call CFSocketEnableCallbacks or CFSocketDisableCallbacks.
* In _GSocket_Get_Mac_Socket() no longer disable callbacks and also do not
add the runloop source which combined with the above change has the
same effect as before.
* In _GSocket_GUI_Destroy_Socket() do not remove the runloop source because
_GSocket_Disable_Events() should have and even if it didn't Mac OS X
will clean it up in CFSocketInvalidate()
