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.

This matches the spec, https://drafts.csswg.org/css-values/#angles, which says:
> All <angle> units are compatible, and deg is their canonical unit.
And https://drafts.csswg.org/css-values/#compat, which says:
>When serializing computed values [...], compatible units [...] are converted into a single canonical unit.
And also other implementations (Blink always serializes angles as degrees in
computed style for example).
Also allows us to get rid of quite a bit of code, and makes computed angle value
representation just a number, which is nice.

This was consistently faster in the benchmark (even when counters were disabled,
which was slightly suspicious, but...).
Anyway, it's not really much code, most of it is FFI copy-pasta.

Extract the common parts of `animated::Color` and `computed::Color` out
into `generics::color::Color<T>` that is generic over the type of
RGBA color.

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" ... />

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

It's just a struct aggregating stylesheets + CascadeData, with a quirks_mode
parameter because XBL sucks so bad.

Bindgen doesn't know how to derive debug for a Gecko font family list. Hopefully
it doesn't need to.
