This ensures that the pointer is always either null or a valid nsIContent after
the call to Rollup returns, and avoids potentially leaving it as garbage. An
alternative approach would be to make the call sites responsible for ensuring it
is set to nullptr if the function returns false, but this seems safer.

The relevant frame classes are:
SubDocumentFrame
ListControlFrame (only when used for (non-e10s?) comboboxes)
PluginFrame
ViewportFrame
MenuPopupFrame
The view is now created in the frame's Init() method, except for
ViewportFrame which has its view assigned by the frame constructor
via a SetView() call.

Views are used for PluginFrame which inherits nsFrame, not nsContainerFrame,
so it's more appropriate that these methods should live in nsIFrame/nsFrame.

This just decouples nsAutoRollup from the widget class, which it isn't really
bound to anyway because the internal data is static. We'll need to be able to
use nsAutoRollup independently in the next patch.

This patch is written by the following script with some manual adjustment to
the comment in nsRubyTextContainerFrame.cpp and nsRubyFrame.cpp, and
nsColumnSetFrame's constructor.
function rename() {
find layout\
-type f\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -r "s/$1/$2/g" "{}" \;
}
rename "nsReflowStatus *([a-zA-Z0-9]*) = NS_FRAME_COMPLETE" "nsReflowStatus \1"
rename "([a-zA-Z0-9.*]*) *= NS_FRAME_COMPLETE;" "\1.Reset();"
rename "([a-zA-Z0-9.*]*) == NS_FRAME_COMPLETE" "\1.IsEmpty()"

Weak frames are stored in a linked list, so are not fast. Hence they are not meant to be used when there can be a lot of them active at the same time. When constructing large selects with lots of options we create one for every option.
There's no need to use a weak frame for a reflow callback as we can just cancel the reflow callback in the Destroy function.
This is the bulk of the changes.
- DisplayItemScrollClip is removed. Instead, we will have 1) ActiveScrolledRoot
and 2) DisplayItemClipChain.
- ActiveScrolledRoot points to a scroll frame and allows traversing up the
scroll frame chain.
- DisplayItemClipChain is a linked list of clips, each clip being associated
with the ActiveScrolledRoot that moves this clip.
- Each display item has an ActiveScrolledRoot and a clip chain.
- nsDisplayItem::GetClip returns the item of the clip chain that scrolls with
the item's ASR. The separation between "regular clip" and "scroll clips"
mostly goes away.
- Tracking clips in the display list builder's clip state happens very
similarly to how regular clips used to be tracked - there's a clip chain for
content descendants and a clip chain for containing block descendants. These
clip chains are intersected to create the combined clip chain.
- There are strict rules for the ASR of a container item: A container item's
ASR should be the innermost ASR which the item has finite clipped bounds with
respect to.
- At some point in the future, ASRs and AGRs should be reunified, but I haven't
done that yet, because I needed to limit the scope of the change.

During the refactoring of nsSliderFrame::SetCurrentPositionInternal in Bug 957445, one
of the two calls to nsSliderFrame::UpdateAttribute was missed. This resulted in the position,
identified with nsGkAtoms::curpos, not being updated immediately after the call to
nsSliderFrame::SetCurrentThumbPosition

Delete the "or 0 for no movement in that direction" from the CanAdjustEdges
document in nsMenuPopupFrame.h because the only caller in nsResizerFrame.cpp
never passes 0 to it.
