Right now we do a lot of useless string copying. In order to avoid transcoding
to utf-16 during layout, make sure to use nsCString at a few related places.
I may revisit this since we're storing other line names as atoms in some places.
So it may be better to just use atoms everywhere.
But that'd be a different patch either way.

This doesn't clean up as much as a whole, but it's a step in the right
direction. In particular, it allows us to start using simple bindings for:
* Filters
* Shapes and images, almost. Need to:
* Get rid of the complex -moz- gradient parsing (let
layout.css.simple-moz-gradient.enabled get to release).
* Counters, almost. Need to:
* Share the Attr representation with Gecko, by not using Option<>.
* Just another variant should be enough (ContentItem::{Attr,Prefixedattr},
maybe).
Which in turn allows us to remove a whole lot of bindings in followups to this.
The setup changes a bit. This also removes the double pointer I complained about
while reviewing the shared UA sheet patches. The old setup is:
```
SpecifiedUrl
* CssUrl
* Arc<CssUrlData>
* String
* UrlExtraData
* UrlValueSource
* Arc<CssUrlData>
* load id
* resolved uri
* CORS mode.
* ...
```
The new one removes the double reference to the url data via URLValue, and looks
like:
```
SpecifiedUrl
* CssUrl
* Arc<CssUrlData>
* String
* UrlExtraData
* CorsMode
* LoadData
* load id
* resolved URI
```
The LoadData is the only mutable bit that C++ can change, and is not used from
Rust. Ideally, in the future, we could just use rust-url to resolve the URL
after parsing or something, and make it all immutable. Maybe.
I've verified that this approach still works with the UA sheet patches (via the
LoadDataSource::Lazy).
The reordering of mWillChange is to avoid nsStyleDisplay from going over the
size limit. We want to split it up anyway in bug 1552587, but mBinding gains a
tag member, which means that we were having a bit of extra padding.
One thing I want to explore is to see if we can abuse rustc's non-zero
optimizations to predict the layout from C++, but that's something to explore at
some other point in time and with a lot of care and help from Michael (who sits
next to me and works on rustc ;)).

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.
ExtremumLength is the keyword type for css sizing properties, so we
could use cbindgen.
In Gecko, we use nsStyleCoord to store the sizing properties, and use
integer values to check the enum values, so I keep the macros in nsStyleConsts.
Even though we need to convert the enum type into integer, we still have
benefits to reduce the complexity of converting Rust into C++, and leave
the simplified mappings in C++ for better readability.

I put Balance as the first item in StyleColumnFill because it is the default
value.

Most of it is automated by:

%s/nsStyleContentType/StyleContentType/g
But I removed some parentheses by hand.

Refactored StyleComplexColor to support "complex" blending between
background (numeric) color and foreground color (currentColor).
Made explicit the distinction between numeric, currentColor and a
complex blend in Gecko and Stylo.
This is to support SMIL animation, for example, of the form:
<animate from="rgb(10,20,30)" by="currentColor" ... />

And use the C++ ErrorReporter only to actually output errors.
ErrorReporter was so complicated because well, it was always enabled and had to
do a bunch of caching to not be (more) slow.
But since bug 1452143 it's disabled by default, so we can simplify this setup a
lot.
Also while at it make the error reporting pref a static pref so that we don't
mutate globals from CSS parsing unless we're actually reporting errors.

Pretty much the same setup we have for document.
We have the awkwardness of having to check containing shadow manually for
ShadowRoot because it's not available in TNode (and making it available added a
bit more complexity that wasn't worth it IMO).

This is needed to serialize computed URLs correctly from getComputedStyle.

Note that we also drop the dead optional aReusableSheets argument from
the async parsing path, since it was always null.

This patch basically does:
* Add descriptor setters and generation count to CounterStyleRule in
Servo. (This code is mostly based on the old code inside
nsCSSCounterStyleRule for handling mutation.)
* Use RawServoCounterStyleRule in CounterStyleManager.
* Add ServoCounterStyleRule and remove nsCSSCounterStyleRule.
Test change:
* "fixed" was parsed as and thus serialized to "fixed 1", but Servo
doesn't do so. It preserves whether the number presents. Either way
is probably fine.

This patch does the following things:
* Create a new class ServoFontFaceRule for CSSOM of @font-face rule
which mostly follows how nsCSSFontFaceRule was implemented.
* Remove the old nsCSSFontFaceRule and binding code to create it.
* Have FontFace backed by Servo data via making mRule and mDescriptors
of the class hold RawServoFontFaceRule like ServoFontFaceRule.
To keep this patch small, it effectively just delays the conversion
from Servo data to nsCSSValue from parsing to using. This may cause
worse performance if the font set is flushed repeatedly. Supposing we
don't flush font set very frequently, it may not be a big deal.
We may still want to remove the intermediate nsCSSValue conversion at
some point, and have everything converted to their final form directly
when used, but that can happen in followups.
There are some unfortunate bits from this change:
* We lose style sheet for logging in FontFaceSet. This is probably not
all that worse, because we wouldn't have that before either if the
page doesn't use CSSOM to visit it. But we should figure out some
approach to fix it anyway.
* InspectorFontFace no longer shares the same rule object as CSSOM.
This isn't really a problem if the @font-face rule isn't very mutable.
Unless we want to make the rule returned from InspectorFontFace to be
mutable (i.e. via inspector), not using the same object probably isn't
too bad.
This patch switches the code we use to serialize stuff in FontFace and
CSSFontFaceRule, which leads to some failures in tests. Specifically,
the expected changes including:
* Value of font-family now can be serialized to identifier sequence like
font-family property. The old code always serializes it to string,
but it doesn't seem to have different requirement than the property.
Blink can serialize to identifier as well.
* Family name inside local() is also changed to use the same way as
family names elsewhere (i.e. can be identifier sequence). Blink has
the same behavior as the old code, but I don't think it's a big deal.
* The order of descriptors serialized gets changed. I don't think it
matters at all.
* Empty string as font-family via using string syntax is no longer
considered invalid for FontFace. I don't find it is mentioned anywhere
that it should be specifically treated invalid.

The new StaticPrefs machinery means that StylePrefs can be removed.
Note that this approach mirrors all static prefs into Rust, but I have only
updated structs.rs for the prefs that Stylo uses.
On a CLOSED TREE, since a sheriff closed the tree while I was about to land this
via autoland.
