systemctl: automatically turn paths and unescaped unit names into proper unit names

Browse Source 
This makes sure that

  systemctl status /home

is implicitly translated to:

  systemctl status /home.mount

Similar, /dev/foobar becomes dev-foobar.device.

Also, all characters that cannot be part of a unit name are implicitly
escaped.
