Lennart Poettering 0c28d51ac8 units: further lock down our long-running services
Let's make this an excercise in dogfooding: let's turn on more security
features for all our long-running services.

Specifically:

- Turn on RestrictRealtime=yes for all of them

- Turn on ProtectKernelTunables=yes and ProtectControlGroups=yes for most of
  them

- Turn on RestrictAddressFamilies= for all of them, but different sets of
  address families for each

Also, always order settings in the unit files, that the various sandboxing
features are close together.

Add a couple of missing, older settings for a numbre of unit files.

Note that this change turns off AF_INET/AF_INET6 from udevd, thus effectively
turning of networking from udev rule commands. Since this might break stuff
(that is already broken I'd argue) this is documented in NEWS.
