perf tools: Introduce trigger class
Use 'trigger' to model operations which need to be executed when an
event (a signal, for example) is observed.
States and transits:
OFF--(on)--> READY --(hit)--> HIT
^ |
| (ready)
| |
\_____________/
is_hit and is_ready are two key functions to query the state of a
trigger. is_hit means the event already happen; is_ready means the
trigger is waiting for the event.
