It's a bit useless to keep a set of invalid properties if we're going
to use them just to reject lookups into another key. This makes it more
consistent with the cascade / no-references code, and should not change
behavior.

There are better ways, plus the existing code didn't handle aliases at
all (not that it needed to, but it's better if it does).

Most of the change is moving sets around to be static functions on
LonghandIdSet. I think I like that pattern, but I can also make the new set a
global static and add mako code to be `pub` or something.
Though I think the LonghandIdSet::foo().contains(..) pattern is nice to read :)

When you're in a ShadowRoot and can share style with a sibling, the sharing code
is smart enough to skip document author rules.
But then it could get confused if you also include document rules, since
revalidation selectors are matched against these.
This is not a correctness issue, because we're matching more than what we need,
and avoid sharing if we failed.
Also fix the detection for user rules in any_applicable_rule_data.

It doesn't make much sense to return const UniquePtr<Foo>& for something that
can't be null, it's just confusing.
Also make more stuff actually const.

For now, we keep supporting the prefixed version, since there are examples/instructions
on the Web that don't include an unprefixed value.

Before this patch we were only optimizing the case of a single selector, which
is fine, but not enough to catch ones like .foo .bar or so.
This patch allows us to optimize classes and tags in the rightmost compound,
while keeping the current optimization for #id selectors.
Need to profile this, but code-wise should be ready for review.

Also remove specified-value-only keywords, since those are handled
only in Rust code and C++ doesn't need to know about them.

1. Add a new preference, layout.css.step-position-jump.enabled, for
step(_, jump-*) timing functions.
2. We still keep JumpEnd and End tags, even though there is no difference
between them. Therefore, we could disable the preference if needed.
3. Update the calculation of StepTiming to match the algorithm in the spec.
4. For servo, we implement the correct step function algorithm except
for the handling of before_flag. This could be fixed later.

First, we generate StyleComputedTimingFunction by cbindgen from Rust, and use
it in nsTimingFunction, so we could copy it directly without handling
the different memory layout. However, we have to rewrite the
nsTimingFunction and mozilla::ComputedTimingFunction for this.
Second, the rust-bindgen seems cannot generate the correct generic members
from complex C++ templates, especially for the nested template struct,
(https://github.com/rust-lang-nursery/rust-bindgen/issues/1429)
So we have to hide StyleTimingFunction to avoid the compilation errors.

We make sure the step number is always positive, so using
computed::Integer is safe and can derive ToComputedValue.

TimingFunction is defined in a separate spec (i.e. css-easing), instead
of transform, so we move it into a different file.

frames() timing function was removed from the spec, so we drop it.
Besides, some devtool tests are removed because they use frame(). I will
add them back by using new step function later.

See the extended commit message for the following spec change:
6b36d41ebc
Basically, by failing to take the absolute value, for certain content we can end
up doing division by zero which will mean that the test included in this patch
will cause an assertion to fail in debug builds and return
"matrix(NaN, NaN....)" in release builds.

This change removes directives NS_STYLE_ANIMATION_PLAY_STATE_* and replaces the

Revert "style: Make the transitions code make sense again."
This reverts commit d6092fae27.
This change actually makes transitions start, and our code for stopping
transitions is just bogus, so we just keep re-starting them over and over, which
is not good.
