Merge branch '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.6-integration

* '4.6' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  Revert "Add a children private property needed for QML to support QGraphicsObject"
  Revert "struct -> class, it's better."
  Revert "Add NOTIFY to size property so QML bindings are working fine."
  Revert "Better handling for NOTIFY in QGraphicsWidget regarding geometry changes"
  Revert "Add a a layout property in QGraphicsWidget."
  Add a workaround for a bug in Mac filesystem watcher.
  Another "off by 1" problem in OpenVG - in paths this time.
  Doc: Added links and notes to modules, ActiveQt and XMLPatterns docs.
  Compile on MingW
  struct -> class, it's better.
  Add a a layout property in QGraphicsWidget.
  Fix QFileSystemModel to not install useless watchers on the filesystem
