 We merged very recently `0c19ce7bdece5906e035e71d3fb682632c8bb9cb` which
 introduced a problem that made all the control events to not work.

 In a nutshell, the macro `ANY_EVENT_IS_INTERESTING()` is doing it wrong.
 The event passed to the macro should be masked before tested using
 `EVENT_MASK_`. And we shouldn't use `EVENT_IS_INTERESTING()` which only
 apply to a single event.

 Fortunately, tor wasn't released so we can just fix it.
