This is the only -moz-box special-case that isn't related to the
visibility: collapse behavior.
After this is done, we can put the collapse behavior in a chrome-only
property, and remove the -moz-box display values and migrate the
-moz-box properties to modern flexbox automatically.

It's a more natural place for it to live, since it concerns only the
root view.
Clean up a bit while at it, and factor out the window size constraints,
which we're going to use momentarily.

Move it to the mozilla::widget namespace.
Use enum classes for transparency, popup type, popup level, etc.
Mostly automated with sed, but there were a few manual changes required
as well in windows code because they relied on Atomic<TransparencyMode>
working (which now doesn't because TransparencyMode is 1 byte instead of
4 bytes).

SetFrame() is equivalent to `operator=`, so external callers can use `operator=`
instead. For the two callers wanting to set `nsFrameList` to `AbsoluteFrameList`
in `nsCSSFrameConstructor`, removing SetFrame() disallows it. However, we can
easily change the declaration from `nsFrameList` to a `AbsoluteFrameList` to
resolve the problem.

This patch doesn't change behavior, and eliminates copy construction of
nsFrameList via utilizing const-references to store the return value of
`GetChildList()`.
nsFrameList::Clone() is added in case the caller wants a copy of a list.
This is the first step toward making nsFrameList a move-only class.

RemoveFramesAfter and ExtractTail have similar purpose, so we really should keep
one of them to avoid confusion.
They have the following minor differences:
1. RemoveFramesAfter() keeps aFrame in the list, while ExtractTail() returns it.
2. If aFrame is empty, RemoveFramesAfter() returns the entire list, while
ExtractTail returns an empty list.
It's more convenient for the existing callers to use the RemoveFramesAfter(), so
ExtractTail is unneeded.
After this patch, both RemoveFramesAfter() and RemoveFramesBefore() return the
entire list if aFrame is nullptr.
Rename RemoveFramesAfter() to TakeFramesAfter() for symmetry with
TakeFramesBefore().
This change shouldn't change the behavior.

It's unused on mozilla-central, and Thunderbird can just use the canvas
frame as regular (X)HTML documents, so just use a canvas frame instead
of an nsRootBoxFrame for XUL as well.
nsRootBoxFrame was needed because of various XUL-specific things like
tooltips and so on lived there. But with the move away from XUL, that
functionality has been added to nsCanvasFrame already, behind a
principal check instead.
This also allows simplifying our background propagation setup, which was
only half-working for XUL documents (this bug is a consequence of that).
With this, most of the callers of nsCSSRendering::IsCanvasFrame can go.
They're only two of the frames that would return true for that that
actually paint backgrounds (nsCanvasFrame and nsRootBoxFrame), so the
codepaths in display list building and painting can just check
frame->IsCanvasFrame() instead.
The remaining caller to that function is
nsContainerFrame::SyncWindowProperties, and the change is also legit, in
the sense that the only thing SyncWindowProperties() really cares about
is propagating the max/min-width constraints from the root element's
style to the view/widget, and the only frame that would return true from
IsCanvasFrame and have a view is the viewport frame which is the root of
the frame tree.

The goal of this patch is to change the SVG max-content size to match blink and
webkit to fix the webcompat issues in bug 1521882 and bug 1651754.
If a percentage width/height attribute on inline axis is explicitly set, we fall
back to the default replaced element size to avoid regressing bug 1162418.
Otherwise, we use 0 as SVG's max-content size in order to be compatible with
blink and webkit.
When computing replaced elements's max-content inline-size, its preferred
aspect-ratio and block-size can transfer to inline axis. The logic is the same
as if the element has an 'auto' inline-size. Hence the modification in
ComputeSizeWithIntrinsicDimensions().
This patch also removes the SVG's intrinsic size dependency on an arbitrary
container from the previous layout result in `SVGOuterSVGFrame::GetPrefISize()`.
bug 1340715 comment 1 explains why the code is unsound.
