Implement LoopKeepAlive for EventBase

Summary: LoopKeepAlive can be useful to tell EventBase, that loop() shouldn't return even if there are no events registered, because some tasks will later be added via runInEventBaseThread. While at least one LoopKeepAlive is alive - EventBase::loop() behaves like EventBase::loopForever().
