<!-- Please describe your changes on the following line: -->
Use common DOM constructor idioms in `MessageChannel`. Also, remove the falliable from the result, since that seems to match the spec better https://html.spec.whatwg.org/multipage/web-messaging.html#dom-messagechannel

Delay reftest screenshot while WR frame is rendering
This PR addresses the theory that #24726 occurs when WR is performing an async frame render and the reftest screenshot decides it's time to synchronously read the framebuffer. If there have not been any completed frames rendered yet, that would yield the page background colour.
The changes in this PR introduce an additional layer of synchronization - the compositor stores an AtomicBool value that indicates whether we know that a WR frame has started rendering, which is set to true when an IPC request from layout that submits a new display list is received. This bool is set to false when WR notifies us that a frame has been rendered. The screenshot code refuses to take a screenshot if the bool is true, causing us to delay taking a screenshot until there is no frame pending.
Add support for WebGL2 framebuffer attachments
Adds an initial implementation for the framebuffer attachments introduced with WebGL2 and the related enums and constrains checks.

Take origin from current window instead of creating a new one in event of reflow
Everytime a new `LayoutContext` was created, it created a new origin which
caused endless stream of image loads to occur in case of reflow. The reason
for this was that the existing image, although cached successfully, was not
used because the entry in hashmap did not match because of different(new)
origin.
This is solved by storing the origin of a window in enum `ScriptReflow` and
used in creating new `LayoutContext` in case of reflow.

This allows rendering stacking context content in the proper order. We
also need to add a new pseudo stacking context for atomic inlines in
order to preserve proper rendering order in some cases.

This adds very rudimentary support for paint order in stacking context.
In particular z-index is now handled properly, apart from issues with
hoisted fragments.
Everytime a new LayoutContext was created, it created a new origin which
caused endless stream of image loads to occur in case of reflow. The reason
for this was that the existing image, although cached successfully, was not
used because the entry in hashmap did not match because of different(new)
origin.
This is solved by storing the origin of a window in enum ScriptReflow and
used in creating new LayoutContext in case of reflow.

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
Add OpenSSL 1.1.1 build check, Update HSTS Preload list
* This variant also works with cross-compilation. PR should fail in CI on Android at first:
The net crate successfully compiled after switching to OpenSSL 1.1.1 on Android. It seemed openssl.sh doesn't need any changes.(?)
* Updated HSTS preload list and public suffix list.
* Configured OpenSSL [SECLEVEL=2](https://www.openssl.org/docs/man1.1.1/man3/SSL_CTX_set_security_level.html) like [Debian](https://wiki.debian.org/ContinuousIntegration/TriagingTips/openssl-1.1.1) Stable:
> As a result RSA, DSA and DH keys shorter than [2048 bits](16a5a9bb78/docs/BR.md (6153-subscriber-certificates)) and ECC keys shorter than 224 bits are prohibited.
* Although all other crates compile I generally get a `libscript-fe019dd3e0a4e06d.rlib: bad extended name index at 8` error on simpleservo_jniapi, I guess Debian Testing is too new and I just haven't found the right steps so far.

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.

This adds an intermediary data structure that allows the display list
builder to move through the fragment tree in stacking context painting
order. Spatial nodes are built during this phase and all display list
items are added to the end of the display list.
