Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-1 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-1:
  add static QChar::is(High|Low)Surrogate methods
  Increase tooltip margin for cleanlooks+gtk
  Fixes a crash in QGestureManager when unregistering recognizers.
  Propagate LocaleChange event from application to widgets.
  Support updating system locale data on Symbian
  QMap: make sure we never access forward and backward through typed Node structs
  Don't quote $COMPILER because it may contain flags
  Unix configure: fix sed pattern extracting C and C++ flags from mkspec
  qdoc: Added more API topics. Are these important?
  Prevent accelerators from firing on X11 and QWS during a drag
