Merge branch '4.7' of scm.dev.nokia.troll.no:qt/qt-s60-public into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/qt-s60-public:
  Build fix for transition effect support on S60 5.0.
  Make EGL surface transparency working on Symbian.
  Splitview flag should also be updated to inputcontext
  QGraphicsView with vertical scrollbar flickers when splitview opens
  Splitview: opening a context menu should not re-position of focusItem
  Trigger fullscreen transition effects properly on app exit.
  Do not use SetSurfaceTransparency() on raster.
