This is mostly just a convenience shorthand to avoid running the same
boilerplate/error-checking code in the implementation of the 'width' and
'height' attributes, for the benefit of callers that need both sizes. But,
beyond that convenience: this also lets us elegantly express the case where an
image simply lacks an intrinsic width and/or height (not due to any error, but
simply because it's e.g. an SVG that has no preferred size in either or both of
its axes). This is a state we'll need to be able to detect and give special
treatment to in a forthcoming patch for bug 1935269.

This patch doesn't change behavior; it's just a rename.
Without this, it's easy to get confused and assume that img.intrinsicSize would
just be a shorthand for img.width and img.height -- but it's not. (It has
different units from the 'width' and 'height' attributes, and in some cases --
e.g. the VectorImage implementation -- it queries for its answer in a different
way from how 'width' and 'height' do.
(I'm doing this partly because I'll soon be adding a new attribute that *does*
just represent img.width and img.height, and that new attribute will also be
named something like "intrinsicSize"; and I want to minimize confusion between
that new attribute and this existing one.)

AspectRatio already has a way of representing a null / invalid ratio,
and there are some cases (broken sizes or invalid SVGOuterSVGFrame
ratio) where we might get Some(AspectRatio()).
It's not a meaningfully different state, and IMO we shouldn't treat it
differently.

All its members are optional, so we can just use it as a plain struct
rather than Maybe<> all around, which simplifies the code and prevents
silly bugs like bug 1779592.
Mostly automatic via:
rg -l 'SVGImageContext' . | xargs sed -i 's/Maybe<SVGImageContext>/SVGImageContext/g'
With trivial build fixes.
Not intended to change behavior.

We'll probably want to do something more accurate in the future with a
custom clang static analysis pass which validates that XPIDL interfaces
have the expected vtable and struct layout, however doing so would be
more involved than the string matching done in this patch.
In addition to checking for extra virtual methods, we'll likely also
want to check for data members on interfaces, and reject them unless the
class is marked as `[builtinclass]` in addition to some other attribute
which we'll need to add to prevent them from being implemented in Rust
(as c++ data members will not be reflected by the rust macro).
There were 2 instances of a comment which contained the word 'virtual'
within a CDATA block. These comments were moved out of the CDATA block
to avoid triggering the error.

This changes the way we deal with page use counters so that we can
handle out of process iframes.
Currently, when a parent document is being destroyed, we poke into all
of the sub-documents to merge their use counters into the parent's page
use counters, which we then report via Telemetry. With Fission enabled,
the sub-documents may be out of process. We can't simply turn these
into async IPC calls, since the parent document will be destroyed
shortly, as might the content processes holding the sub-documents.
So instead, each document during its initialization identifies which
ancestor document it will contribute its page use counters to, and
stores its WindowContext id to identify that ancestor. A message is
sent to the parent process to notify it that page use counter data will
be sent at some later point. That later point is when the document
loses its window. It doesn't matter if the ancestor document has
already been destroyed at this point, since all we need is its
WindowContext id to uniquely identify it. Once the parent process has
received all of the use counters it expects to accumulate to a given
WindowContext Id, it reports them via Telemetry.
Reporting of document use counters remains unchanged and is done by each
document in their content process.
While we're here, we also:
* Limit use counters to be reported for a pre-defined set of document
URL schemes, rather than be based on the document principal.
* Add proper MOZ_LOG logging for use counters instead of printfs.

Since we don't support downscaling animated images we'll need something like this even we were to try to request a smaller sized decode.

This makes EXIF orientation metadata honored by default.
Introduce OrientedPixel and UnorientedPixel typed rects and sizes and
use them throughout RasterImage so that we don't confuse which we want.
The reason for doing this rather than having the imgLoader wrap every
RasterImage it creates with an OrientedImage is that returning the
wrapper messes with various notifications, as OrientedImage is not an
ImageResource.
(It would be even better if the JPEG decoder could decode to imgFrames
handling the EXIF orientation itself, but that's a more complicated
change.)

With WebRender, we had observed that the print preview for animated
images was not displaying correctly. It should display the first frame
but it was showing nothing the first time the preview was opened. Once
the decoded image was available in the cache, it would display
correctly if the preview was reloaded.
The StartDecoding and RequestDecode variants always requested
FRAME_CURRENT for animated images. They should use FRAME_FIRST for
static requests / FrozenImage. Correcting this fixes the print preview.

The img decode API allows a web author to request that an image be
decoded at its intrinsic size and be notified when it has been
completed. This is useful to ensure an image is ready to display before
adding it to the DOM tree -- this will help reduce flickering.

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.

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.
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.
