b07ebbae6b Replace all uses of the style::stylearc alias with servo_arc. 
The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).

style: Undo the optimization for grabbing animation rules from the style data. 
This is unfortunate, but for now it complicates things, I would like not needing
a ElementData to get the style of an Element in order to fix all the
getDefaultComputedStyle bugs.

654661df36 Hook into the Gecko leak checking machinery. 
Since we're going to stop asserting that all RuleNodes have been
destroyed by the time the RuleTree is destroyed, we want reliable leak
checking.

2b5c56e6a8 Move match and cascade temporaries to CurrentElementInfo 
Before this change, the `ComputedStyle` struct that is part of permanent style
data per element holds 2 `StrongRuleNode`s (unvisited and visited) and 2
`Arc<ComputedValues>` (unvisited and visited).

Both rule nodes and the visited values don't actually need to be here.  This
patch moves these 3 to new temporary storage in `CascadeInputs` on
`CurrentElementInfo` during the match and cascade process.  Rule nodes are
pushed down inside the `ComputedValues` for later access after the cascade.
(Visited values were already available there.)

The permanent style data per element now has just the `Arc<ComputedValues>` for
itself and eager pseudo-elements (plus the `RestyleHint`).

4deab0f06a Fix calculation of base styles to drop animation rules 
It seems that changeset 97ce9ed5b0
mistakenly changed the check that a cascade level to keep is *not* an
animation level to a check that it *is* an animation level.

a7882cfeb9 Match and cascade visited styles 
To support visited styles, we match and cascade a separate set of styles any
time we notice that an element has a relevant link.

The visited rules and values are held in `ComputedStyle` alongside the
regular rules and values, which simplifies supporting various APIs like
`cascade_primary_and_pseudos` which expect easy access to previously matched
rules.

To simplify passing the additional values around, an additional reference to the
visited `ComputedValues` is placed inside the regular `ComputedValues`.

d30c4fe79d Use SMIL override value that has been processed during animation-only restyles for normal restyle. 
In the case where we process an element which has SMIL animations in normal travesal
the SMIL styles must have been computed in animation-only restyles. So we
have only to pick the computed styles instead of recomputing it.
