qtmultimedia/tests/auto/qmediaplaylistnavigator/tst_qmediaplaylistnavigator.cpp
Michael Goddard a6128410da API unit tests from Maemo API test team. 
A large number of tweaks and changes to original tests, and refactor
a lot of the mock backends to reduce duplication.

Changed viewfinder test case to use mock service and provider so
that it matches the image capture test case.
