sd-event: instrument sd_event_run() for profiling delays
Set SD_EVENT_PROFILE_DELAYS to activate accounting and periodic logging of the distribution of delays between sd_event_run() calls. Time spent in dispatching as well as time spent outside of sd_event_run() is measured and accounted for. Every 5 seconds a logarithmic histogram loop iteration delays since 5 seconds previous is logged. This is useful in identifying the frequency and magnitude of latencies affecting the event loop, which should be kept to a minimum.
