Replaced Nokia copyrights with correct Digia copyrights.
Text in front of copyright is now retained:
** File is part of Foo, Copyright Nokia... ->
** File is part of Foo, Copyright Digia...
Replaced Nokia contact details with Digia's.
Removing "All Rights Reserved" no longer leaves an empty line.

Used the following command:

find . -path '*/3rdparty/*' -prune -o -exec grep -ilI -E
'.*Copyright.*Nokia.*|.*Contact.*Nokia.*' {} \; |
tee >(xargs sed -i -r

Too much house-keeping is needed to run tests from resources,
so start the process of removing support to discourage the
creation of poor test harnesses.
