It felt odd to cache these directly in GlobalScope, but they need to be [SameObject] and the global scope is where the spec implies they go.

Upgrade to rustc 1.43.0-nightly (5d04ce67f 2020-02-13)
~This Nightly doesn’t have rustfmt, so merging this PR is blocked on https://github.com/rust-lang/rust/issues/68917 and upgrading to a Nightly with the fix.~
Fixes#25550
Selection DOM interface (but not actual UI selections)
This is work towards #7492.
I put new tests in the mozilla-specific directory rather than the main tree because I'm not sure how upstreamable they are; I'd like opinions on that point.
This adds a new exposed interface, which I understand from tests/mozilla/interfaces.html is something requiring specific approval from someone allowed to give that approval.
Things that aren't done here:
- The spec doesn't describe what selection/script-and-style-elements.html wants, and what it wants seems to require some sort of layout query.
- Actual UI interactions are not present at all; selection.rs has a few TODOs saying which methods I believe the eventual UI code should call for what actions, but there are a lot of fine points here that I don't know about.
- I haven't touched Node; you can ask if a node's in the Selection's Range the same way you'd ask about any other Range, but there's not a faster path just for selection layout.
Use CE reaction queue when inserting an element from non-fragment parser
<!-- Please describe your changes on the following line: -->
Changed async_html Tokenizer so it can remember whether it's for a fragment and changed servoparser node insertion to respect the CE queue requirements of https://html.spec.whatwg.org/multipage/parsing.html#insert-a-foreign-element; it passes a WPT test.

Add SupportedPropertyNames to Document (also fix iframe getting)
Existing test of named-getting an iframe now succeeds. I added a new test for Object.getOwnPropertyNames(document) based on my understanding of the spec; that test could use a second opinion.
UPDATE: This was trying to do too many things in one PR as originally submitted. It is now using #25572 as a base, and I suggest reviewing that PR before this one to avoid duplicating review effort.

Event dispatch rewritten to align to spec, activate on clicks better
I went over the changes to the event dispatch spec that had accumulated over the past few years, rewriting dispatch/invoke/inner-invoke almost completely and modifying other code where it was relevant. Most of the remaining obvious deviations from spec are things that will only come up when we start handling events in shadow DOM.
I am pushing now because I want to see CI test results, but please do not approve this PR just if automated test improvements look good. I may have broken some actual UI interactions in the course of fixing synthetic events, and some manual testing is needed, including checking that manual interactions with interactive content continue to fire the events they're supposed to.

Make name content attributes consistently atoms and put them in rare_data for fast access
<!-- Please describe your changes on the following line: -->
All codepaths setting the name content attribute now use an atom, which is also stored in rare_data for direct lookup by a get_name method.
Paralleling the get_name method, I added a get_id method, which makes some internal id-lookup cases nicer.
A new test tests for a name setter on every HTML element type. In addition to its overt and upstreamable purpose of checking IDL property reflection semantics, for us this test also hits some Servo assertions that make sure the name is an atom in every case. If the test doesn't crash, even a failed test case still has the attribute as an atom rather than some other type. The failed cases are for elements that we have unimplemented or completely stubbed; I added a few missing name IDL properties to otherwise implemented elements.

Implement "translate" attribute
This attribute is almost a straightforward enumerated one, but the getter value inherits from parents when the content attribute is absent, even when the parents are non-HTML elements. This initial commit is using LocalName::from on a static string; once html5ever has a release with "translate" in the built-in local name list, a small change will be needed.

Make performance observers take "type" and "buffered" options without panicking.

I updated the observe() method to align with spec, and fixed the borrow duration bug @jdm pointed out in #25589 so it wouldn't cause a hard crash. Some tests go from failing to passing, but others go from early failing to later timeout; performance observers still aren't doing the right thing in all cases.

Make HTMLFormControlsCollection rooted at the form's root, not rooted at the form itself
<!-- Please describe your changes on the following line: -->
We'd been misreading the first line of https://html.spec.whatwg.org/#dom-form-elements. The collection needs to be rooted higher than the form itself, so it can contain form controls elsewhere in the document with a form= content attribute. It is, as far as I can tell, unspecified whether "rooted at the form's root" is meant to live-update to a new root if the form is moved to another tree, and I'm assuming it doesn't have to.

Let EventSource fail fast on bad schemes
<!-- Please describe your changes on the following line: -->
EventSource went into an infinite reconnect loop in some cases where tests wanted it to go into a hard error state; this addresses the cases where that happens because the url isn't even http(s) and will thus definitely never result in an event stream.
https://github.com/web-platform-tests/wpt/issues/4311 suggests the tests might just be too picky here; the spec does use the word "may" on relevant behavior.

Expose DOMHighResTimeStamps at lower res
As explained in https://www.w3.org/TR/hr-time-2/#clock-resolution and tested in a few WPT tests, we're not supposed to show Javascript the full resolution of OS timestamps. This fixes that on all the DOMHighResTimeStamp interfaces that weren't already limiting themselves to integer milliseconds.
The specific choice of how to coarsen the resolution is extremely bikesheddable; I commented the reasoning for my arbitrary choice but I admit it's arbitrary.
A couple tests of timing resolution still fail, but because they're seeing undefined and NaN values due to unimplemented attributes (#25658).

Mechanism to allow Servo to prompt the user
This blocks the embedder thread (compositor thread). Not ideal. I don't think it's too much work to only block script, I'll do that in a follow up bug.
Fix#23376
@Manishearth we have a few new APIs. Hopefully this will cover your needs. A thing I haven't implemented yet is a way to ask the user to pick from a list. Let me know if it's something you'll need.
This query is used to get the clientTop, clientWidth, clientHeight,
clientLeft properties of DOM objects. "NodeGeometry" doesn't really
capture what these properties do as they often are returning the width
of element border.
