  3. Fix main loop (#456)

    * Fix main main loop
    
    * When event reordering is disabled, skip poll() call if there were remaining
      events in the ring buffers but processing timeout was reached. This fixes
      lost events in alloc_live_heap mode:
      * producer does not notify profiler since consumer has not processed all available events
      * poll call waits until timeout is reached
    * When event reordering is enabled:
      * reduce timeout for poll() call to 10ms because profiler cannot consumer
        all available events because of reordering algorithm that allows for some
        latency between events.
      * Reduce max sample latency to 50us
    
    * Report more info
    
    * Enable reordering of events by default
