This was an oversight in bug 1520154. We kept the -moz- version in the specified
value but not the computed value.
That's a very peculiar way of making aliases work. This makes them work
consistently as many other aliases instead.
Also, add an assert that would've caught this much much earlier.

The comment about the white-space property was wrong, we don't enforce it with

This needs https://github.com/eqrion/cbindgen/pull/362, but I expect it to be
uncontroversial. I'll add a patch to this bug when it's merged to update it.
cbindgen historically didn't include these, but it turns out to be pretty useful
to generate constants for the style crate (since the binding crate is
`servo/ports/geckolib`).
An alternative is to get a completely different cbindgen-generated header for
these, but that seems a bit wasteful. This generates the constants with the
Style prefix (so we'll get `StyleMAX_GRID_LINE` for example), which is very
ugly. But we probably want to eventually stop using the Style prefix and use a
namespace instead, plus it's trivial to do `auto kMaxLine = StyleMAX_GRID_LINE`,
for example, so it's probably not a huge deal.
Another alternative would be to use associated consts, which _are_ generated by
cbindgen. Something like:
```
struct GridConstants([u8; 0]);
impl GridConstants {
const MAX_GRID_LINE: i32 = 10000;
}
```
Which would yield something like:
```
static const int32 StyleGridConstants_MAX_GRID_LINE = 10000;
```
I'm not sure if you find it preferrable, but I'm also happy to change it in a
follow-up to use this.
We need to fix a few manual C++ function signature definitions to match the C++
declaration.

The style system already atomizes all CustomIdent values, which means that we're
just wasting memory and CPU by doing string copies all over the place.
This patch fixes it. This also simplifies further changes to use as much of the
rust data structures as possible.
I had to switch from nsTHashtable to mozilla::HashTable because the former
doesn't handle well non-default-constructible structs (like NamedLine, which
now has a StyleAtom, which is not default-constructible).

Right now we do a lot of useless string copying. In order to avoid transcoding
to utf-16 during layout, make sure to use nsCString at a few related places.
I may revisit this since we're storing other line names as atoms in some places.
So it may be better to just use atoms everywhere.
But that'd be a different patch either way.

I want to enable in Nightly to evaluate (in the medium term) shipping it without

This should make all the pieces come together.
Note that we don't need to look at the snapshot for ::part() for now (other than
when selector-matching normally) because I decided to just restyle the element
for now when the part attribute changes.
::part() can't affect descendants anyway (as long as we don't do the forwarding
stuff), and eager pseudo-elements are handled during the normal element restyle,
so it seems to me that adding all the complexity that we have for classes to
part may not be worth it at least yet.

I still haven't implemented each_part(), so this will do nothing yet.
The cascade order stuff is fishy, I know, and I'll fix in a followup if it's

These are owned by the element and not referenced from the stylesheets.
They're referenced from the rule tree, but the rule nodes don't measure their
style source (since they're non-owning).
So unconditionally reporting them even though it's a refcounted object is ok.
While at it, remove some other fields from the old style system that are no

We were getting away with it for the pre-existing usage of the style crate,

complain. But servo_arc is definitely used in tests.
