Before opening new IPv4/IPv6 server sockets, chronyd will check for matching reusable sockets passed from the service manager (for example, passed via systemd socket activation: https://www.freedesktop.org/software/systemd/man/latest/sd_listen_fds.html) and use those instead. Aside from IPV6_V6ONLY (which cannot be set on already-bound sockets), the daemon sets the same socket options on reusable sockets as it would on sockets it opens itself. Unit tests test the correct parsing of the LISTEN_FDS environment variable. Add 011-systemd system test to test socket activation for DGRAM and STREAM sockets (both IPv4 and IPv6). The tests use the systemd-socket-activate test tool, which has some limitations requiring workarounds discussed in inline comments.
