step(_, jump-*) timing functions.
2. We still keep JumpEnd and End tags, even though there is no difference

First, we generate StyleComputedTimingFunction by cbindgen from Rust, and use
it in nsTimingFunction, so we could copy it directly without handling

Second, the rust-bindgen seems cannot generate the correct generic members

This reverts the relevant bits from #21746 so that style and dependencies can

This is important because:
* `selectors` is a published crate.
* Gecko compiles with stable (more or less).
I reviewed that PR under the assumption that the union feature was stable, since
untagged unions are stable since 1.19, but turns out that smallvec uses non-Copy
types in unions, which are still unstable.
This leaves the union feature used on Servo, so that it gets testing, taking
advantage of features being additive.
This cherry-picks servo/servo#21788.
We had a mix of 0.6.2 and 0.6.5 (which is the current release),

Summary:
The behavior the WG proposed is way more subtle than what that bug implements,
including:
* Implementing two logical overflow longhands.
* Expanding the overflow shorthand to different longhands depending on the

Meanwhile, Blink hasn't done the swap and will ship the same behavior that we
shipped in Firefox 61 (bug 1453148), that is, overflow-x, then overflow-y.
So I think lacking a clear way forward we should revert this change and preserve

- And the `atom!` macro for each atom indexes into nsGkAtoms::sAtoms[] using

- Moves hash() from the top level into create_and_insert_some_stuff().

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.

1. We will add more shape-like types in the future, so it's better to
use union to reduce the memory usage.
2. Those shape-like types are mutual exclusive, so we could use union to
wrap them.

It used to be this way because of lifetime issues (plus the shadow
datas were in RwLocks at some point IIRC). Now we guarantee that as long as the
element is away the cascade data is as well, so we don't need to thread it
around.

We only have this so that ::-moz-placeholder keeps serializing as
::-moz-placeholder, but I don't think anybody really cares.
Edge aliases ::-webkit-input-placeholder to ::-ms-input-placeholder at parse
time as well, as can be seen in:
```
let s = document.createElement('style');
s.innerHTML = `input::-webkit-input-placeholder { color: red };`;
document.body.appendChild(s);
document.body.innerHTML = s.sheet.cssRules[0].cssText;
```
And I think this is more consistent with what we do for CSS properties that are
aliases.

The '-moz-menulist-button' value currently behavies identically to the
'menulist-button' value. This is not implemented as an alias because later
patches in this patch series will change the behavior of our pre-existing
'menulist-button' value to more closely match what Chrome does.

Always assume allowed-for-all-content. There are a couple callers which weren't
doing that:
* A unit test -> removed.
* ComputeAnimationDistance: Used for testing (in transitions_per_property), and
for the animation inspector. The animation inspector shouldn't show
non-enabled properties. The transitions_per_property test already relies on
getComputedStyle stuff which only uses eForAllContent.
* GetCSSImageURLs: I added this API for the context menu page and such. It
doesn't rely on non-enabled-everywhere properties, it was only using
eInChrome because it was a ChromeOnly API, but it doesn't really need this.

And general Element logging. We now print all the attributes for comparison.
If this turns out to be too verbose we can change it to diff them or something.

:root can't change without getting unbound from the tree so no fancy stuff other
than that needed.
This removes a lot of revalidation and attribute invalidation matching from the
Chrome, and looks like it should be a good idea in general.

We have a different order in nsCSSPropertyId for no good reason. The only
invariant there is that longhands come before shorthands, and shorthands before
aliases.
Luckily that's also an invariant that NonCustomPropertyId has, so we can reuse
them.

The patch at bug 1478391 comment 6 changed the way the math in Scrollbarbutton*
worked, which pretty surely caused this.
Restore the original order and math to be the same as before bug 1478391.

This builds on bug 1428676 and introduces StyleAppearance, which replaces the
NS_THEME_* constants.
Really sorry for the size of the patch.
There's a non-trivial change in the gtk theme, which I submitted separately as
bug 1478385.

We use the same setup WR uses, which is checking-in the files.
But I think it's much better than keeping the two things in sync manually :)
When you add a new value, you need to add it to the rust source, then run the
command, but since it doesn't need to build the style crate (it uses the Rust
AST, doesn't build) there's no problem.

The values in the boolean context depend on its feature. For examples, in the
case of prefers-reduced-motion 'no-preference' means false and 'reduced' mean
true in the boolean context, whereas in the case of prefers-contrast
'no-preference' means false and other two values, 'high' and 'low' means true
in the boolean context. To support it we introduce a child struct of
nsCSSKTableEntry that has an additional field representing the value in the
boolean context and use it when we have no specified value in the media feature
(i.e. in the boolean context).

Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need
to match document rules, see the linked SVGWG issues.
But blocks_ancestor_combinators goes away, which is nice since it's on a very
hot path.
Test Plan: WPT for style invalidation, covered by existing tests otherwise.
