    ikev2: estimate time spent by helpers and state transitions
    
    Time is always tracked, but for the moment, only logged when --debug
    "base", "all", or "cpu-usage" (more details) is enabled.
    
    Because states can magically appear and disappear, it needs to use
    so_serial_t and hash table lookup.  Mumble something about the
    observer effect.
    
    Because code switches states midway through a state transition, things
    may be billed to the wrong state, or not at all.  Mumble something about
    switching current thread midway through a transition being a
    bad idea.
