systemctl,loginctl,machinectl: add --signal=list
This lists numerical signal values:
$ systemctl --signal list
SIGNAL NAME
1 SIGHUP
2 SIGINT
3 SIGQUIT
...
62 SIGRTMIN+28
63 SIGRTMIN+29
64 SIGRTMIN+30
This is useful when trying to kill e.g. systemd with a specific signal number
using kill. kill doesn't accept our fancy signal names like RTMIN+4, so one
would have to calculate that value somehow. Doing
systemctl --signal list | grep -F RTMIN+4
is a nice way of doing that.
