Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  Fixed regression in QPixmap::size() for null pixmaps.
  Make test less sensitive to platform specifics
  Doc: Further QML improvements.
  Doc: Minor improvements to QML-related documentation.
  The test livelock of QTimer is now expected to work
  Make sure mapSelectionFromSource does not return a selection with invalid ranges.
  QEventDispatcherUnix: do not process too many timer if other events need to be processed first
  Doc: Continued work on the QML documentation.
  Doc: More work on the QML documentation.
  Doc: More work on the declarative API documentation.
  Doc: Some editing and tidying up.
  Doc: Added a missing file.
  Doc: Fixed text in license headers.
