conntrackd: add systemd support
This patch adds basic systemd support. The feature can be enabled/disabled at configure time: ./configure --disable-systemd Also, at runtime in conntrackd.conf General { Systemd on|off } (by default it's enabled both at runtime and at configure time) * tell systemd about conntrackd readiness: When conntrackd starts, it will send systemd the data "READY=1". At the point the data is sent, conntrackd is fully ready to work (configuration was OK, sockets OK, et all), so other actions depending on conntrackd can be safely chained in the machine boot process. * tell systemd about conntrackd shutting down: If the admin kills conntrackd with `conntrackd -k', the data "STOPPING=1" will be send to systemd so it learns about the daemon shutting down. Same for manual signals. * watchdog support: The admin can configure systemd to watch the conntrackd daemon and perform some actions if conntrackd dies: restart it, reboot the machine, etc...
