When the underlying image request (imgIRequest) changes for an image, we
need to ensure that we invalidate the cached WebRenderImageData such that
the image container stored therein is updated to be for the correct
image. This gets a little tricky because some display items store both
the current and previous images, and choose to display the latter if the
former is not yet ready. We also don't know what image the image
container belongs to. As such, we now compare the producer ID of the
current frame in the image container, to the expected producer ID of the
current image request. If they don't match, we must regenerate the
display list.

Originally we would invalidate image containers synchronously when
SVGRootRenderingObserver::OnRenderingChange was called. However at this
point in time, the layout tree is in the middle of updating its own
state, and triggering a paint will be problematic. Animated vector
images did not suffer from this problem because they would defer to the
next refresh tick, but non-animated do not receive refresh tick events.
As such, we should just defer the invalidation to immediately after the
layout tree has finished updating itself.

If a vector image has an image container, it is unlikely the caller will
call VectorImage::Draw (and thus Show indirectly) to display the image.
As such, WebRender was missing subsequent invalidations and not
regenerating the rasterized surface as expected. Thus we now resume
honoring the invalidations if we updated the image container.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This needs to add a few of includes in other places which were relying on the
massive (now gone) list in nsDocument.h.
I also needed to move an AnimationTimeline destructor out of line because it
relied on dom::Animation being defined, yet Animation.h includes
AnimationTimeline.h, so include hell.

This patch makes ImageContainer create a SharedSurfacesAnimation object
when it detects that we are using shared surfaces and are producing full
frames.

The lack of clarity over which functions initiate observing and which don't
is a headache since it makes it hard to reason about what's going on. This
rename makes it explicit in the function names.

If FLAG_HIGH_QUALITY_SCALING is used, we should use
SurfaceCache::LookupBestMatch just like how it is done in RasterImage.
This may provide an alternative size at which we should rasterize the
SVG instead of the requested size. Since SurfaceCache imposes a maximum
size for which it will permit rasterized SVGs, we should also bypass the
cache entirely if we are well above that and simply draw directly to the
draw target in such cases.
With WebRender, it is somewhat more complicated. We will now return
NOT_SUPPORTED if the size is too big, and this should trigger fallback
to blob images. This should only produce drawing commands for the
relevant region and save us the high cost of rasterized a very large
surface on the main thread, which at the same time, looking as crisp as
a user would expect.

In addition to the image container, the draw result can also be useful
for callers to know whether or not the surface(s) in the container are
fully decoded or not. This is used in subsequent parts to avoid
flickering in some cases.
This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

Move the initialization of SharedSurfacesParent from the compositor
thread creation to mirror the other WebRender-specific components, such
as the render thread creation. Now it will only be created if WebRender
is in use. Also prevent shared surfaces from being used by the image
frame allocator, even if image.mem.shared is set -- there is no purpose
in allowing this at present. It was causing startup crashes for users
who requested image.mem.shared and/or WebRender via gfx.webrender.all
but did not actually get WebRender at all. Surfaces would get allocated
in the shared memory, try to register themselves with the WR render
thread, and then crash since that thread was never created.
