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

* '4.7' of scm.dev.nokia.troll.no:qt/qt-qml:
  QDeclarativeDebugClient: Fix gcc warning
  QmlDebugService: Check that there is a receiver before sending messages
  If a type is registered under several names, share the attached property object
  QmlViewer: Fix typo in comment
  QmlViewer: Fix assert on exit (Windows)
  QDeclarativeDebugService: Add bc autotest
  Make QmlDebug protocol more robust
  Minimize parameter changes on glyph cache textures
  Only set maskTexture sampler uniform once
  Only repopulate the glyph cache when we know something could have changed
  Remove unnecessary attribute changes
  Invalidate QStaticText coord cache when texture size changes
