This patch invalidates the style for `::selection`, which will restore the
behavior before the regression.
However, it's still not quite correct, because repaint is not triggered. Given
that `::selection` requires some major change to implement
https://github.com/w3c/csswg-drafts/issues/2474, we can address this problem
later.

This patch produces the following serialization:
```
input | computed value
------------------------------
1. "auto" "auto"
2. "auto auto" "auto"
3. "15px auto" "15px"
4. "15px" "15px"
```
i.e. If the second value is 'auto', then it's omitted from our serialization,
because it's implied.
Besides, we update the wpt to address this spec issue:

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).
Differential Revision: https://phabricator.services.mozilla.com/D35119
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.

Should not serialize default shape-outside circle() function radius.
The ToCss impl of Circle and Ellipse turn out to be identical in specified and computed value, thus move them to generics.

I want to enable in Nightly to evaluate (in the medium term) shipping it without
the part forwarding, once the cascade order and importance issues are fixed, and
that we pass all the tests that don't involve forwarding.
That is, I want to monitor whether having ::part() causes compat issues or not.
Differential Revision: https://phabricator.services.mozilla.com/D32649
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.
Differential Revision: https://phabricator.services.mozilla.com/D32648
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
fine with you. I moved the sorting of the rules to rule_collector, since it
seemed to me it was better that way that duplicating the code, and those
SelectorMap functions only have a single caller anyway.
Differential Revision: https://phabricator.services.mozilla.com/D32647
Unlike for :host() or ::slotted(), or regular rules, we don't need a whole
SelectorMap<>, so gotta make the code a bit more generic.
Differential Revision: https://phabricator.services.mozilla.com/D32646
This grows the selector struct, but only in 32-bit, since in 64-bit we take
space from the alignment padding that we're paying due to having the size of the
slice as a word.
Differential Revision: https://phabricator.services.mozilla.com/D32645
Still does nothing, since we still do not collect part rules, but this is all
the plumbing that should allow us to invalidate parts when attributes or state
change on their ancestors.
Differential Revision: https://phabricator.services.mozilla.com/D32642
It looks like bug 1547939 will stick, given how fast the other regressions came
in for bug 1337655.
We haven't seen any regression from this, and it seems unlikely that we'd want
this code back.
This blocks further improvements to the style system. Simplifying this code
allows me to remove all the conversion code for gradients.
Let me know if you think it's premature and I'm happy to wait, but I really want
to see this code gone :)

From this point on, the webkit-prefixed CSS features that were previously
protected by this pref will now be unconditionally enabled.
Differential Revision: https://phabricator.services.mozilla.com/D33807
They're not used internally either, so remove all ability to address them.
I haven't removed the implementation yet, as some of them are quite complex, and
I don't have a mac / windows build. We should do that when this hits release
though.
