This changes behavior some, by moving the code involved from "before we remove
the attribute" to AfterSetAttr. But I think it should be OK, and SVG elements
can't sanely implement BeforeSetAttr right now...

On MacOSX, more precisely if full keyboard access is not enabled on MacOSX,
we skip focusing link elements in SVG with tab key, so if there is no more
elements to be focused in the SVG, the focus will be moved outside the SVG.
To prevent this situation, there needs more focusable elements in the SVG.

It's a sub-class of nsAtom, useful for cases where you know you are dealing
exclusively with static atoms. The nice thing about it is that you can use
raw nsStaticAtom pointers instead of RefPtr<>. (In fact, the AddRef/Release

In order to tailor certain security checks to the caller that is attempting to
load a particular piece of content, we need to be able to attach an
appropriate triggering principal to the corresponding requests. Since most
HTML content is loaded based on attribute values, that means capturing the
subject principal of the caller who sets those attributes, which means making
it available to AfterSetAttr hooks.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

When nsSVGUtils::getBBox is called on <use> element:
1. Call from SVGGraphicsElement::getBBox(WebAPI):
According to the spec, getBBox should return the bbox as the union box of
children in user space.
2. Call from mask/ clip-path or filter painting:
Since we want to paint those elements in the coordinate space formed by
<use>(bug 537623), getBBox should return the bbox as the union box of
children in coordinate system of <use>.
Depend on the use case, we return the bbox of an <use> element on different
coordinate system. In this patch, I bring in a new
flag(eInUserSpaceOfUseElement) so that nsSVGUtils::getBBox can return bbox on

There are two overloads of nsSVGLength2::GetAnimValue:
1. float nsSVGLength2::GetAnimValue(nsSVGElement*) const;
2. float nsSVGLength2::GetAnimValue(SVGSVGElement*) const;
In Bug 265894, I created SVGViewportElement as a base class of SVGSVGElement.
SVGSVGElement::GetViewBoxTransform was moved to SVGViewportElement in that
refactoring. The local variable 'ctx' in that function was changed from
SVGSVGElement to SVGViewportElement, which when passed to
nsSVGLength2::GetAnimValue caused us to switch from calling the overload that
takes a SVGSVGElement to the overload that takes a nsSVGElement, which is not
what we want.
This patch changes the argument type of the nsSVGLength2::GetAnimValue overload
that takes an SVGSVGElement to take an SVGViewportElement instead, which causes
the GetAnimValue(ctx) calls in SVGViewportElement::GetViewBoxTransform to call
the correct GetAnimValue overload again.

These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is only used in ways that nsCStrings can also be used
(i.e. no null checks or implicit conversions to |char*|).
In every case the patch trivially replaces the nsXPIDLCString with an
nsCString. (Also, there are a couple of unused nsXPIDLCString variables that
the patch simply removes.)
This patch moves measurement of ComputedValues objects from Rust to C++.
Measurement now happens (a) via DOM elements and (b) remaining elements via

objects.

The 'servo-style-structs' and 'computed-values' sub-trees are new. (Prior to
this patch, ComputedValues under DOM elements were tallied under the the
'dom/element-nodes' sub-tree, and ComputedValues not under DOM element were
ignored.) 'servo-style-structs/sundries' aggregates all the style structs that
are smaller than 8 KiB.
Other notable things done by the patch are as follows.
- It significantly changes the signatures of the methods measuring nsINode and
its subclasses, in order to handle the tallying of style structs separately
from element-nodes. Likewise for nsIFrame.
- It renames the 'layout/style-structs' sub-tree as
'layout/gecko-style-structs', to clearly distinguish it from the new
'layout/servo-style-structs' sub-tree.
- It adds some FFI functions to access various Rust-side data structures from
C++ code.
- There is a nasty hack used twice to measure Arcs, by stepping backwards from
an interior pointer to a base pointer. It works, but I want to replace it
with something better eventually. The "XXX WARNING" comments have details.
- It makes DMD print a line to the console if it sees a pointer it doesn't
recognise. This is useful for detecting when we are measuring an interior
pointer instead of a base pointer, which is bad but easy to do when Arcs are
involved.
- It removes the Rust code for measuring CVs, because it's now all done on the
C++ side.

All the SizeOf{In,Ex}cludingThis() functions take a MallocSizeOf function
which measures memory blocks. This patch introduces a new type, SizeOfState,
which includes a MallocSizeOf function *and* a table of already-measured
pointers, called SeenPtrs. This gives us a general mechanism to measure
graph-like data structures, by recording which nodes have already been
measured. (This approach is used in a number of existing reporters, but not in
a uniform fashion.)
The patch also converts the window memory reporting to use SizeOfState in a lot
of places, all the way through to the measurement of Elements. This is a
precursor for bug 1383977 which will measure Stylo elements, which involve
Arcs.
The patch also converts the existing mAlreadyMeasuredOrphanTrees table in the

Because we want to remove nsAdoptingString. We have other variants that don't
use nsAdoptingString, which can be used instead. There are three basic
patterns.
1. The easiest case is when we don't check for success.
> nsAdoptingString s = Preferences::GetString("foo");
> foo(s);
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> foo(s);
2. The next case is when we check if the result is empty.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s.IsEmpty()) { ... }
becomes:
> nsAutoString s;
> Preferences::GetString("foo", s);
> if (s.IsEmpty()) { ... }
3. The final case is when we null check the result.
> nsAdoptingString s = Preferences::GetString("foo");
> if (s) { ... }
becomes:
> nsAutoString s;
> nsresult rv = Preferences::GetString("foo", s);
> if (NS_SUCCEEDED(rv)) { ... }

Most of this patch is updating a few places that use gfxMatrix to use
the equivalent-but-differently-named functions on MatrixDouble:
- Translate/Rotate/Scale get turned into PreTranslate/PreRotate/PreScale
- Transform(Point) gets turned into TransformPoint(Point)
- gfxMatrix::TransformBounds(gfxRect) gets turned into
gfxRect::TransformBoundsBy(gfxMatrix).
- gfxMatrix::Transform(gfxRect) gets turned into
gfxRect::TransformBy(gfxMatrix).
The last two functions are added in this patch as convenience wrappers
to gfxRect instead of Matrix.h because we don't want Matrix.h to "know"
about gfxRect (to avoid adding gecko dependencies on Moz2D). Once we
turn gfxRect into a typedef for RectDouble these will be eliminated
anyway.

Using SVG SMIL it is possible to animate the class attribute of an element using
markup such as the following:
<style>
.red {
fill: red;
}
</style>
<svg>
<circle cx="50" cy="50" r="30" fill="blue">
<set attributeName="class" to="red" begin="1s"/>
</circle>
</svg>
In Gecko, Element::GetClasses handles this case by looking for an animated class
string when the element in question is an SVG element.
This patch causes our Servo bindings to use GetClasses when querying attribute
values for selector matching.
Note that animating the class attribute is *not* expected to affect attribute
selectors such as `circle[class="red"]`. It does in Chrome, but that is due to
a Blink bug where animating attributes using SMIL affects the result of
getAttribute:
https://bugs.chromium.org/p/chromium/issues/detail?id=735820
This patch adjusts the behavior for both the GeckoElement case and the
ServoElementSnapshot case.

In order to facilitate the movement of code with side-effects called by Element::SetAttr to Element::BeforeSetAttr and Element::AfterSetAttr, Element::AfterSetAttr should have access to the old value of the attribute. This includes information about whether there was previously a value set or not.
Accomplishing this involved passing an additional argument through functions that find and change the old attribute value in order to ensure that we can differentiate between an empty old value and an absent old value (attribute was not set).
Note that while I tried to ensure that accurate values (and their absence) are reported to Element::AfterSetAttr, I largely ignored SVG. While the old value reported for SVG values should be however accurate the value already being reported to SetAttrAndNotify was, SVG elements do not currently report unset values properly because they will never pass a null pointer to SetAttrAndNotify.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

This patch removes handling of the 'attributeType' attribute so that we behave
as if attributeType is always 'auto'. This means that for CSS properties we
always animate them as CSS properties (i.e. we animate them as part of the
SMIL override stylesheet) rather than mapped attributes.
The one special case is width/height on an outer SVG. Previously we animated
this as a mapped attribute since Web compatibility requires that the
width/height on an outer SVG, when set explicitly, are mapped to style.
However, we can produce the same behavior by animating these as CSS properties
(as opposed to mapped attributes). There is no observable difference in results
returned by the SVG DOM APIs, only the level at which the result is added to
the cascade: the SMIL override stylesheet instead of the attribute animation
presentation hint level.
As part of this patch, we animate width/height on outer SVG elements as CSS
properties as opposed to mapped attributes both for consistency and also so
we can remove the animated mapped attribute code altogether.

This means that implementations of BeforeSetAttr no longer need to UpdateState.
Those UpdateState calls will be removed in a bit.

This removes the requirement that BeforeSetAttr comes before AttributeWillChange
(which needs the preparsed new value).
