This is needed to avoid hitting the assertion "Why did this not get
handled while processing mRestyleRoots?" in CollectRestyles, because we
have a restyle posted for a frame that has the NEEDS_FRAME bit flag set.
- 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.

This also changes the functionality a little bit to track independent
per-property mutation counts and independent "content active" status.

This patch does the following:
* Move nsIFrame::IntrinsicSize to mozilla::IntrinsicSize so that it can
be forward-declared.
* Move a number of templated inline nsLayoutUtils methods to nsIFrame.
* Use mozilla::layout::FrameChildListID instead of the
nsIFrame::ChildListID typedef in nsLayoutUtils.h.
* Move nsReflowFrameRunnable to its only user, nsProgressMeterFrame.cpp.
* Make a number of functions requiring nsIFrame.h out-of-line.
* Remove the nsIFrame.h #include from nsLayoutUtils.h and add it to the
places which require it implicitly.
This depends on bug 898333 in order to avoid causing:
TEST-UNEXPECTED-FAIL | chrome://mochitests/content/chrome/dom/tests/mochitest/chrome/test_focused_link_scroll.xul | Assertion count 1 is greater than expected range 0-0 assertions.
due to the assertion:
###!!! ASSERTION: Shouldn't be trying to restyle non-elements directly: '!aContent || aContent->IsElement()', file ../../../layout/base/nsStyleChangeList.cpp, line 62
The assertion count change in layout/generic/crashtests/571995.xhtml is
expected because it changes us from having 7 of:
###!!! ASSERTION: Shouldn't be trying to restyle non-elements directly: '!aContent || aContent->IsElement()', file ../../../layout/base/nsStyleChangeList.cpp, line 62
with the stack:
mozilla::ElementRestyler::CaptureChange(nsStyleContext*, nsStyleContext*, nsChangeHint) [layout/base/nsChangeHint.h:191]
mozilla::ElementRestyler::RestyleSelf(nsRestyleHint) [layout/base/RestyleManager.cpp:2304]
to only having one. This is expected since this patch changes
RestyleSelf to only call CaptureChange for the first continuation or
block-in-inline sibling.
(This is part of the patch stack making change hints apply across all
continuations and block-in-inline siblings. In this case, however, the
change hint only needs to apply once, globally.)
