master: Added reuse_port setting to inet_listeners, which enables SO_REUSEPORT if available. After forking a new service process, a new listener socket is created for each such inet_listener. Linux v3.9+ added SO_REUSEPORT feature, which should distribute clients more uniformly to the processes. I'm not sure if this makes any difference in BSDs. At least in Linux v3.9 there was still a bug that if the number of listening processes changed, some TCP handshakes might not finish. I don't see if this has already been fixed, so this is probably safe to use only for services whose process count doesn't change (e.g. process_min_avail is set high enough).

Initial commit for v2.0 master rewrite. Several features are still missing. --HG-- branch : HEAD
