Move windowing code out of the compositor

This is mainly just moving code around, in preparation for further changes to
the "windowing" API.
Factors out DOM traversal, keeping the code in `parallel` free of traversal-specific logic.

DOM traversals and Flow traversals look very similar. This patch unifies them
with the preorder/postorder pattern. Hopefully, it also opens the door for writing
the traversal code only once, instead of the duplication we have today.

Use Gecko's simpler Bloom filter instead of one based on hash
stretching.

This preserves the usage of the Bloom filter throughout style recalc,
but the implementation is rewritten. Provides a 15% improvement on
Guardians of the Galaxy.

Add type IDL attr for submittable elements
Fix <input>.checked
Implement extremely basic form submission (fixes #3554)
Correct <input>.value
Address review comments
Update wpt expectations
auto merge of #3642 : Manishearth/servo/form-submit, r=jdm

This is missing a lot of parts, so it doesn't really make any real-world form submission work yet. It provides a skeleton on which the missing bits can be filled in.

What works:
 - `<input>` elements except for `type=file`
 - GET/POST methods
 - URLencoded `enctype`s (default)
 - Submission via `<form>.submit()` only

Stuff that needs to be done for most simple real-world cases to work: 
 - [Working text input](https://github.com/servo/servo/pull/3585)
 - Click handlers for `<submit>`
 - Possibly `<textarea>` support
 - Support for the other two enctypes (#3649)

Todo:
 - Correctly implement [planned navigation](https://html.spec.whatwg.org/multipage/forms.html#planned-navigation) using `TrustedFormAddress`  (#3648)
 - [Correctly implement form owners.](https://github.com/servo/servo/issues/3553) Requires html5ever and some discussion of the spec.
 - `<input type=file>` support
 - Image submit support
 - Browsing contexts/targets
 - Support for non-`<input>` controls
 - Validation (?)
 - Dirname (?)

I haven't yet gotten to the root of this, but it's breaking the other PRs.
