In some versions of python, the XML parser was unable to cope with
the XML identifier coming after the comment that contained the license
header.

The previous docs format, CC 1.0, is not recommended by GENIVI, and
the preferred one is CC-BY-SA 4.0.

Other license changes are:
* Add Creative Commons copyright headers to documentation.
* Add copyright headers to test code.
* Add copyright headers to dbus XML that belongs to the NSC.
* Update copyright headers to GENIVI's standard.

Notable exceptions are:
* dbus XML that is used to communicate with other services
  (e.g. common/nsm-consumer-dbus.xml) has not had copyright statements
  added, because the Node Startup Controller does not own that interface.

Remove the use of BusName from service file since this is only valid
for Type=dbus and generates a warning on each boot.

Make sure we use the same spelling of focussed in all places to
avoid confusion.

This missing break previously caused the method
node_startup_controller_application_get_property() to return the
Legacy App Handler when asked to get the Node Startup Controller.

If we don't do this, the callback provided by the application will
not always be called and thus, sd_notify() will only be called if
reading the LUC is attempted. That breaks starting the NSC service
through systemd.

The type of the systemd service is now "notify", because systemd ignores
the "READY=1" notification for all other service types.

Expands the description to explain what it does when it receives the
"handle-begin-lucregistration", "handle-register-with-luc" and
"handle-finish-lucregistration" signals.
