When a new frontend connection is instantiated, actconn global counter is incremented. If global maxconn value is reached, the connection is cancelled. This ensures that system limit are under control. Prior to this patch, the atomic check/increment operations were done directly into listener_accept(). Move them in a dedicated function increment_actconn() in frontend module. This will be useful when QUIC connections will be counted in actconn counter.
