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: Keyboard navigation regression in QTreeView Implement the general blending of ARGB32_pm with SSSE3 QtDeclarative debugging: Add an option not to stream the properties of an object.
