This improves cache locality and reduces allocations during parsing.
Note that this reverses the iteration order within a sequence of simple selectors,
but that shouldn't matter.
stylo: Bug 1353628 - Support shorthand properties for CSS Transition.
These patches add shorthand properties into TransitionProperty, so we can parse the shorthand properties properly and create transitions for them.

In order to make TransitionProperty::parse() also work on shorthands, we
should add shorthands into TransitionProperty, and add the arms in other
functions which match TransitionProperty.

stylo: Centralize stylesheet handling.
This is needed for both bug 1357461 and bug 1273303, where I plan to add smarter
invalidations than what we have now.
Also, it's cleaner.
Ideally I'll move this onto stylist, though that may require extra work to make
it work fine for Servo, so for now let's just do the obvious thing.

1. We need to call get_after_change_style, which is the computed styles
without transition rules, while process_animations.
2. If we have after-change style, we may replace the new computed values with
after-change style, according to whether we really need to update
transitions.
3. There are some cases we don't update transitions, so we need to early
return. might_needs_transitions_update() will check it first and it
will filter out most common cases.
4. needs_transitions_update() will check each property and existing running
transitions to make sure we really don't need to update transitions.
The logic of this function is similar with that of
nsTransitionManager::DoUpdateTransitions().

Add one FFI to check if there is any transition in CSSTransitionCollection.
This will be used to check if we need to update transition and if we
should compute the after-change style.

style: Fix dynamic changes of attributes when combined with :not.
This makes the dependency tracker properly recurse into simple selectors inside the current complex selector to find the appropriate dependencies.
We can't still remove the outer visitor because we need it for stuff like `:not(.foo + bar)`, but I plan to get rid of it in a followup as long as try comes back green.

To make it possible to check the rule type when parsing lengths, we need to pass
the `ParserContext` down through many layers to the place where length units are
parsed.
This change leaves it unused, so it's only to prepare for the next change.

I wanted to add an environmental variable to disable the style sharing
cache for gecko, but the current pattern involves lazy_static!, which
involves an atomic operation on lookup, which is a bit hot to do each
time we try to share styles. This makes that work happen once per
process.
stylo: Add -moz-element support
Implemented -moz-element for background property.

style: Refactor the selectors crate to remove ad-hoc logic.
Also refactors a lot of the restyle hint code to use these new hooks, and removes a lot of hacks in servo that shouldn't be needed because of correct handling of restyles due to attribute changes.
I just smoketested this, so going for a full try run now.

While we're at it, we also eliminate the 'unknown' dom depth for the
bloom filter. Computing depth has negligible cost relative to the
amount of work we do setting up the bloom filter at a given depth.
Doing it once per traversal should be totally fine.
I originally separated the elimination of unknown dom depth from the
traversal changes, but I got bloom filter crashes on the intermediate
patch, presumably because I didn't properly fix the sequential traversal
for this case. Given that the final state is green, I just decided to
squash and move on.
