There are errors with multiple docbook xml file while
make documentation.

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.

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

This commit simplifies the build process by adding an autogen script
to handle the creation of an m4 directory and execution of gtkdocize
and autoreconf.

Documentation on building has been updated accordingly.

In test-legacy-app-handling.xml, the timeout was wrong.

In test-target-startup-monitoring, the phrase "Applied the node state N"
had been changed to "Node state N applied" in everywhere but one place.

Replace the old DLT messages in the TargetStartupMonitor test case
documetnation with the ones we currently use.

Add a dedicated COPYING.docs file for this. The license is also
mentioned again in the reference manual itself.

Removed the requirement to restart the system for each test, instead
just restart the node startup controller for each test. The downside of
this is that the dlt.log file is not reset so may become very large.

Reduced the number of DLT log messages to compare against the output.
Instead, only the most relevant lines are included for each test.

Added separate test that the Node Startup Controller registers itself.

Rewrote the descriptions for each test case to be more readable.

Numbered each test case.

Spelling and grammar fixes.
