Currently, NAC always inherits from the closest non-NAC ancestor element,
regardless of whether it is for an element-backed pseudo or not.
This patch changes the inheritance so that for element-backed pseudos, we
inherit from the closest native anonymous root's parent, and for other NAC we
inherit from the parent.
This prevents the following two issues and allows us to remove the
NODE_IS_NATIVE_ANONYMOUS flag:
* Avoiding inheriting from the non-NAC ancestor in XBL bindings bound to NAC.
- This is no longer a problem since we apply the rule only if we're a
pseudo-element, and all pseudo-elements are in native anonymous subtrees.
- This also allows to remove the hack that propagates the
NODE_IS_NATIVE_ANONYMOUS flag from the ::cue pseudo-element from
BindToTree.
* Inheriting from the wrong thing if we're a nested NAC subtree.
- We no longer look past our NAC subtree, with the exception of
::-moz-number-text's pseudo-elements, for which we do want to propagate
::placeholder to.
A few rules from forms.css have been modified because they're useless or needed
to propagate stuff to the anonymous form control in input[type="number"] which
previously inherited from the input itself.

Now that rustfmt is getting close to stable, and work on the style system has died down a bit, it seemed like an opportune time to auto-format the style crates.
The first commit disables import reordering, since tidy and rustfmt don't currently agree on the correct ordering. The second commit does a bunch of manual fixups such that the output of rustfmt passes tidy. The third commit runs rustfmt on the three aforementioned crate.
There are a few dozen warnings in the style crate about lines longer than 100 characters. It would be good to fix these, but I don't have time for that now.

style: Cleanup StyleBuilder.
This is in preparation of a cascade optimization for custom properties.
This fixes various fishiness around our StyleBuilder stuff. In particular,
StyleBuilder::for_derived_style (renamed to for_animation) is only used to
compute specified values, and thus doesn't need to know about rules, visited
style, or other things like that.
The flag propagation that was done in StyleAdjuster is now done in StyleBuilder,
since we know beforehand which ones are always inherited, and it simplified the
callers and the StyleAdjuster code. It also fixed some fishiness wrt which flags
were propagated to anon boxes and text.

This makes an element available in StyleAdjuster, and uses it to replace some of our CascadeFlags (the ones that don't represent restrictions on what's actually cascaded, actually).
That fixes handwaviness in the handling of those flags from style reparenting,
and code duplication to handle tricky stuff like :visited.
There are a number of other changes that are worth noticing:
* skip_root_and_item_based_display_fixup is renamed to skip_item_display_fixup:
TElement::is_root() already implies being the document element, which by
definition is not native anonymous and not a pseudo-element.
Thus, you never get fixed-up if your NAC or a pseudo, which is what the code
tried to avoid, so the only fixup with a point is the item one, which is
necessary.
* The pseudo-element probing code was refactored to return early a
Option::<CascadeInputs>::None, which is nicer than what it was doing.
* The visited_links_enabled check has moved to selector-matching time. The rest
of the checks aren't based on whether the element is a link, or are properly
guarded by parent_style.visited_style().is_some() or visited_rules.is_some().
Thus you can transitively infer that no element will end up with a :visited
style, not even from style reparenting.
Anyway, the underlying reason why I want the element in StyleAdjuster is because
we're going to implement an adjustment in there depending on the tag of the
element (converting display: contents to display: none depending on the tag), so
computing that information eagerly, including a hash lookup, wouldn't be nice.
See each commit for details.

This avoids grabbing the body when values that inherit from the body,
whatever that means, aren't under the body.
In that case we'll get a semi-random value, but that's also mishandled by Gecko
anyways (and probably Blink, though haven't tested), and doesn't really make
much sense.

These are the inter-dependent patches of bug 1392161. We want to handle
extreme small lengths carefully for some properties, such as transform, so we
shouldn't use |Au| as the computed value of specified::Length. Now, we introduce
a new type, CSSPixelLength, which is a wrapper of CSSFloat, and it is the
computed value of specified::Length, so we can keep the fractional part
of computed::Length.

In the case where values in CSS rules changed directly by CSSOM, the old
value in the CSS rule block is immediately replaced by the new one. So if
the element, which is applied to the CSS rule, has running animations, the
new value is used during cascading process in animation-only restyle. Thus
in a subsequent normal restyle, we can't tell whether the value in the CSS
rule has changed or not. As a result, transitions may not be triggered
(bug 1393323) and CSS animations may not be cancelled if the updated
animation-name is 'none' (bug 1392851).
For the latter case of CSS animations where animation-name has been updated to
'none', this patch introduces a workaround whereby we trigger an update of
running animations whenever the traversal is triggered by changes to CSS rules
and we have existing CSS animations.

The only reason why we had the `existing_style_for_style_damage` bit is to apply
some optimizations that we don't have anymore.
I still want to reintroduce a few of them, at least for the non-eager
pseudo-element case... But I think I won't need this at all.
This allows us to remove a fair amount of Gecko code too.

Some properties only accept non-negative values, or values greater than or equal to one. It is possible to produce an negative interpolated values while using negative timing functions, so we have to apply a restriction to these values to avoid getting invalid values.
For example, line-height must be non-negative, but the output progress of some timing functions (e,g. cubic-bezier(0.25, -2, 0.75, 1)) may be a negative value, so the interpolated result of line-height is also negative.

We skipped updating the rule nodes for visited rules during animation-only restyle.
However, this causes isseus that visited style overrides animation styles on visited element.
