If the NetworkManager daemon has been stopped manually we don't want it
to be autostarted by a client request.
[lkundrak@v3.sk: The auto-activation is probably more surprising than useful.
Services that need NetworkManager API should depend on NetworkManager service
directly.
I have no idea what purpose does the D-Bus service file serve nowadays,
but it looks rather hacky (really, activating /bin/false) and the comment
in it suggests that the autoactivating behavior was not intended anyway.
Debian has been shipping this for quite some time and no complains have been
heard.]

Load the thunderbolt-net module if we see a host-to-host connection
and configure the resulting ethernet connection automatically to be
a link-local only one. The latter is done by setting a new udev
property "NM_AUTO_DEFAULT_LINK_LOCAL_ONLY" which is picked up when
we configure the connection for the device.
