It's possible that both this_weight and other_weght have calculation errors
which are approximately equal to f64::EPSILON.

The idea is to turn the simple properties into a blacklist instead really soon,
and fix the offending ones soon after, so that only shorthands and properties
with layout dependence (and maybe the scrollbar properties, because the poke at
LookAndFeel) are not serialized by Servo.

GCC doesn't like StyleComplexColor with constructor in an anonymous
struct in an anonymous union. Replace the use of a union to access
`mBorder[..]Color` fields as an array with an accessor methods.

It's only used for the error path in property parsing, so most of the time is
not useful.
Use the just-introduced NonCustomPropertyId::name to preserve the alias name,
which we were doing by passing the name around.

The six milliseconds spent in Olli's profile make me thing this is not getting
optimized and we expected.
Also move it to NonCustomPropertyId, so it works for aliases properly too.

And make transition-property more correct by serializing --0 unescaped instead

This would cause properties to change the value semantics between, e.g.,
@keyframes and non-@keyframes, which would be observable.
It happens not to be observable since the animation-* and transition-*
properties are not allowed in @keyframes, nor have bits in `contain`, and none
of the two properties are allowed in @page. But I think it's the right thing to
do.
This still causes a quirk like a property value in chrome / user origins being
potentially different if the value is specified via CSS var functions. But I
think that is fine.

We were working around the lack of alias support during parsing in
TransitionProperty by doing a Gecko lookup. That's a hack and is now gone.

Though I think it may be slightly fishy if used in, e.g., a @keyframes block.
For our purposes right now it doesn't make a difference, I think.

Per bug 1322189 we really should. I've copied the setup we have already for
translate / scale, but we should really clean this up a bit more I'd think.
In any case, probably skew should be matched as well...

This patch:
* Makes StyleStructID an enum class, and moves it to the mozilla namespaces.
* Introduces StyleStructConstants with some constants scattered through the
codebase.
* Makes the computed style bits an enum class, and splits mPseudoType and mBits
into their own members, since we were using a uint64_t when we have only a
couple flags and CSSPseudoElementType is a byte. We statically assert that
the number of style structs is less or equal to 32.
* Makes mPseudoTag, mPseudoType and mBits const, since we don't want them to be
mutated from C++, and we still need a few more refactorings (mostly getting
rid of FinishStyle) to avoid mutating ComputedStyle instead.

Also call them "resolve" since it's the general term for computing something
more specific than what you have.
Though I don't feel strongly about that, feel free to push back.
