Most of it is automated by:

But I removed some parentheses by hand.

This changes the order of properties returned from gCS. The old order
doesn't make much sense, and other browsers don't agree on an identical
order either, so it should be trivial to change it. Also the spec isn't
super clear / useful in this case.
Several -moz-prefixed properties are excluded from the list due to their
being internal. I suspect they are never accessible anyway, so probably
nothing gets changed by this.

The EffectSet count does not exactly represent the count what we really need
for AnimationValueMap, but in most cases it matches. For example;
1) The element has two different keyframes animations
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { transform: rotate(360deg); }
}
In this case the number matches.
2) The element has two animations but both keyframes have the same CSS property
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { opacity: 0.1; }
}
In this case the number doesn't match, moreover it results more memory than we
ever needed, but this case is presumably less common.
3) The element has an animation having keyframes for two different CSS
properties.
@keyframes anim {
from { opacity: 0; transform: rotate(360deg); }
}
In this kind of cases, the number doesn't match. But even so, this patch
reduces the opportunities that the AnimationValueMap tries to allocate a new
memory (i.e. less opportunities on expanding the map).
Note that when the hash map is expanded, we do allocate a new RawTable with the
new size then replace the old one with the new one [1], so I believe this
change will reduce the crash rate to some extent.

After bug 1470163 we have some nasty selectors from mathml.css in every page.
We only want to match them against MathML elements.
This patch brings the global revalidation selectors from 14 to 2 in about:blank.
Also halves the ones from XUL documents.

This reduces memory usage because we only need one allocation instead of two
for the dynamic atom and its chars, and because we don't need to store a
refcount and a size. It precludes sharing of chars between dynamic atoms, but
we weren't benefiting much from that anyway.
This reduces per-process memory usage by up to several hundred KiB on my
Linux64 box.
One consequence of this change is that we need to allocate + copy in
DOMString::SetKnownLiveAtom(), which could make some things slower.
Summary:
This should make it easier to report errors, and also reduce codesize.
The reason this was so generic is that error reporting was unconditionally
enabled and was super-hot, but now that's no longer the case after bug 1452143,
so we can afford the virtual call in the "error reporting enabled" case.
This opens the possibility of simplifying a lot the error setup as well, though
this patch doesn't do it.
Test Plan: No behavior change, so no new tests.

We were spuriously reframing the <shadow> because it initially shared style with
the <br>, which ended up being display: none, while the <shadow> should've been
display: contents from the beginning.
lookup_by_rules seems pretty prone to obscure bugs, and also it's pretty
complex... Probably we should try to get rid of it, I'm unconvinced that it's
worth it.
Even with that, in a normal restyle the <details> wouldn't have ended up with a
style. It of course never had it before the reframe because the <shadow> was
display: none, but that doesn't mean it shouldn't have gotten one, since we
detected we needed to go through kids in:
https://searchfox.org/mozilla-central/rev/6eea08365e7386a2b81c044e7cc8a3daa51d8754/servo/components/style/matching.rs#500
That code did happen, but since it's an animation-only restyle, we don't look at
unstyled stuff.
That looks somewhat fishy, but I guess for now it's fine as long as display
isn't animatable.

Do it so that we always try to evaluate the media expression and the modern
syntax last, so that the most specific error message comes up.
