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.

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

We can have cousins in the cache whose parent doesn't match ours, and other
cousins whose parent does. When we encounter one of the former, that's not a
reason to stop lookin for the latter.

With this PR, the only remaining usage of UnsafeNode is the transition stuff, which is servo-only and probably going to be rewritten over the course of stylo. The parallel traversal is now fully typechecked and safe. \o/

<!-- Please describe your changes on the following line: -->
Since https://bugzilla.mozilla.org/show_bug.cgi?id=1321284, we can have multiple disjoint subtrees of elements to style in a document, due to document level native anonymous content not inheriting from the document's element. This patch tweaks the style Bloom filter to allow switching to a new node that has no common ancestor with the old node.

This is not a problem for Servo, because we recovered it without much problem a
few lines below, and we never reached the pathological case where the filter has
one element (the root), and we restyled another element with depth 1.
