Lasse Dalegaard e0db9f3a6e serialhdl: prevent creation of controlling tty ... When `serialhdl` opens a terminal device it must prevent the device from becoming the controlling terminal of `klippy`, as such a terminal will send additional messages to the session leader, e.g. a SIGHUP, which would kill `klippy`. See e.g. #3981. pySerial already does this, but for e.g. `klipper_mcu` we were not doing this ourselves. On Linux a process must set `O_NOCTTY` when opening any file that could potentially be a terminal device, to avoid this. Earlier process daemonization tools prevent this from being an issue by double forking, but under `systemd` a process must take steps to avoid opening a controlling terminal.
