Bug 984226 - Add parameter to OverflowChangedTracker::AddFrame to distingush between frames that need nsIFrame::UpdateOverflow called and frames that only have a transform that has changed. r=dbaron

- OverflowChangedTracker::AddFrame now accepts an enumerated type parameter to
  indicate if the overflow areas of children have changed (CHILDREN_CHANGED),
  the overflow areas of the children have changed and the parent have changed
  (CHILDREN_AND_PARENT_CHANGED), or if only the transform has changed
  (TRANSFORM_CHANGED).
- OverflowChangedTracker::Flush no longer falls back to calling
  nsIFrame::UpdateOverflow when a frame lacks a PreTransformOverflowAreas
  property.
- Added an additional change hint, nsChangeHint_ChildrenOnlyTransform, which
  results in TRANSFORM_CHANGED being passed in to
  OverflowChangedTracker::AddFrame.
- In nsIFrame::FinishAndStoreOverflow, the passed in overflow is now stored as
  the InitialTransformProperty for elements that are IsTransformed().
- Partially corrected Bug 926155, by only calling
  OverflowChangedTracker::AddFrame on parents of the sticky element during
  StickyScrollContainer::UpdatePositions, using CHILDREN_CHANGED.
