We don't have lossy currentcolor in the style system anymore, except for a
single property -moz-font-smoothing-background-color.
I could've converted it into a proper StyleColor and thread down all the
necessary information to the font metrics code.
But it doesn't really seem worth it given it's not exposed to the web, so I just
did the simplest thing, which is making currentcolor compute to transparent to
that specific property.
This patch also removes the stores_complex_colors_lossily code and related,
since now we always can cache computed colors.

To be more similar between Rust and C++. This introduces GenericFontFamily and
exposes that plus FontFamilyNameSyntax to C++, using that where appropriate
instead of plain uint8_t as we were doing.
As a follow-up, as discussed on IRC with Jonathan, we can remove the -moz-fixed
family, and turn it just into an alias of Monospace.
The only non-trivial change is the MatchType changes, but they're ok I think.
The code already assumed at most one CSS generic, and the struct still takes 8
bits. I've verified that the relevant tests are passing (though try is closed).

UA style sheets only ever specify a single generic font family in font-family
properties, so we pre-create a unique, static SharedFontList for each generic
and change the representation of FontFamilyList to be able to refer to them
by their generic ID. This avoids having to share refcounted SharedFontList
objects across processes.

They're only used in forms.css, and only for some anonymous content, which are
not content-accessible in the first place.
The only place where this could be exposed is calling
getComputedStyle(input, "::placeholder"), so I think this should be pretty safe,
but I've added a pref just in case.
While at it, also derive the Parse implementation. Less code is better.

We are always able to produce an x height, but depending on whether the
glyph exists, we sometimes can't produce a zero glyph width.

It's not very easy to understand on its current state, and it causes subtle bugs
like bug 1533654.
It could be simpler if we centralized where the interactions between properties
are handled. This patch does this.
This patch also changes how MathML script sizes are tracked when scriptlevel
changes and they have relative fonts in between.
With this patch, any explicitly specified font-size is treated the same (being a
scriptlevel boundary), regardless of whether it's either an absolute size, a
relative size, or a wide keyword.
Relative lengths always resolve relative to the constrained size, which allows
us to avoid the double font-size computation, and not give up on sanity with
keyword font-sizes.
I think given no other browser supports scriptlevel it seems like the right
trade-off.

I feel a bit weird for using LenghtPercentageOrAuto to implement LengthOrAuto,
but I don't think much other code will use it so it seemed a bit better to me.

We really only have two sets of prefs, one for chrome-like documents
(stuff in chrome docshells + chrome-origin images), and one for the rest.

This may or may not be part of the plan to get rid of nsCSSValue ;)
Option is not usable via FFI, and they should not be needed (we should be
following the shortest serialization principle instead). These patches also do
that, which matches the other transform properties. I think that slight change
is fine, if we can make it work, and consistent with other properties.
Alternative is adding more TransformOperation variants or such, which I rather
not do.

Instead of storing them as LengthPercentage | Number, always store as
LengthPercentage, and use the unitless length quirk to parse numbers instead.
Further cleanups to use the rust representation can happen as a followup, which
will also get rid of the boolean argument (since we can poke at the rust length
itself). That's why I didn't bother to convert it to an enum class yet.

The euclid size is not really used for anything. Also rename it to Size2D to
avoid cbindgen conflicts with values::length::Size.

I want to do this so that I can get rid of Either<>. The reasons for getting rid
of either are multiple:
* It doesn't generate as nice C++ code using cbindgen.
* It isn't that nice to use either from Rust.
* cbindgen has bugs with zero-sized types.
I started using this for ColorOrAuto and a few others, for now.

-moz-tab-size, border-image-outset and border-image-slice.
This is not a particularly interesting patch, just removes some code. We can
remove way more code when a few related properties are also ported.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

This patch:
* Makes LengthPercentageOrAuto generic, and removes a bunch of code fo
LengthPercentageOrNone, which was used only for servo and now can use the
normal MaxLength (with a cfg() guard for the ExtremumLength variant).
* Shrinks MaxLength / MozLength's repr(C) reperesentation by reducing enum
nesting. The shrinking is in preparation for using them from C++ too, though
that'd be a different bug.
* Moves NonNegative usage to the proper places so that stuff for them can be
derived.
I did this on top of bug 1523071 to prove both that it could be possible and
that stuff wasn't too messy. It got a bit messy, but just because of a bug I
had fixed in bindgen long time ago already, so this updates bindgen's patch
version to grab a fix instead of ugly workarounds :)
