do not handle compositor input events when BC is being discarded
prevent firing of timers for discarded BCs
return null for opener is BC has been discarded
bundle discard BC steps into window method
return null in window.opener, if BC has already been discarded
move the window closed check pre-event to script-thread
Fix many WACK errors
These changes ensure that all native dependencies are built with the compiler flags that will prevent forbidden API uses. They also incorporate a fork of rand_os that backports UWP support from more recent rand releases. This is necessary in the short term to avoid having to wait for the entire ecosystem to migrate to the most recent rand release.
Depends on https://github.com/servo/mozjs/pull/200 and https://github.com/servo/rust-mozjs/pull/471.

Do not allow XR session on non user-activated events
This sets the thread in "user interaction mode" when the dispatched event is trusted. I also tried an approach where we would not rely on the dispatched event but just set "user interaction mode" when we get a compositor event (which, we can assume, are only user generated). That worked as well.
Fixes#23787.

Ideally we want to be able to borrow from the DOM during box construction
but that's not playing very well at the moment with the current bridge
between script and layout.
The purpose of this commit is to ensure that the Response object has
access to Timing updates as previously the Response object simply
stored a ResourceFetchTiming struct so updates on ResourceFetchTiming
that were not explicitly done on the Response would not be passed down.
The references to ServoArc are added because Response uses
servo_arc::Arc rather than std::sync::Arc as is used elsewhere. So,
we've switched those other places to servo_arc::Arc instead of switching
Response to std::sync::Arc.
add webidl bindings for DOMStringList
<!-- Please describe your changes on the following line: -->
To prepare for the implementation of `IndexedDB` a DOM interface for `DOMStringList` is added.
This change:
* Adds a new IDL file for `DOMStringList`
* Lists `domstringlist.rs` in `mod.rs`
* Defines a new DOMStruct `DOMStringList`
* Changes some test expectations related to `DOMStringList`

We are not yet able to fully test the functions of `DOMStringList` in the WPT, because it is not possible to create an object of the type `DOMStringList` until e.g. `indexeddb` or `location.ancestorOrigins` is implemented.

Stylo's Gecko wrapper duplicated some logic from the C++ side so
that the Rust compiler would be able to optimize better. Now that
we have xLTO, this kind of manual inlining should not be neccessary
anymore.

For developing properties, we will handle them in an other bug.
Besides, I use an iframe for the test because we create a use counter in
the constructor of Document, which use the prefs to decide what kind of
properties we want to record. So, in the test, we have to reload iframe
to make sure we re-create the document, so does the use counter, to make
sure the prefs work properly.
The two prefs affect the css use counters:
1. layout.css.use-counters.enabled: Allocate use counters, and record
non-custom properties.
2. layout.css.use-counters-unimplemented.enabled: Record all unimplmented
properties into the use counters.
If we disable layout.css.use-counters.enblaed, we don't create use counters
object, so layout.css.use-counters-unimplemented.enabled doesn't work,
either.

This is consistent with the `order` property anyhow, and allows to simplify some
code.
Negatives are still not parsed, but rust uses a similar representation for all
CSS <integer> values and so should C++.

Replace use of gleam in webgl with sparkle.
Rely on https://github.com/servo/sparkle for the GL bindings required to implement Servo's WebGL stack. This does not touch the GL usage in the compositor or webrender, which continue to rely on https://github.com/servo/gleam. This means that any breaking changes to the public GL bindings interface (such as required by https://github.com/servo/servo/pull/24111) only require updating rust-offscreen-rendering-context and rust-webvr, rather than many other crates that are out of our direct control.

These two bugs (bug 1572738 and bug 1572451) are stylo regressions.
When font-family changes, we try to recompute the font-size with a length /
percentage combinations in case the generic family changes, so the user
preferences are kept.
When calc() is involved, we clamp to non-negative too early, via
NonNegativeLength::scale_by.
I think we should generally dump this "try to track font-size across calc()"
thingie, as as various comments note it is not quite perfect, and it's not clear
how it should work in presence of min()/max().
This patch fixes the issue and simplifies code a bit, I may consider removing
this altogether in a follow-up.

Prefetch img, scripts and stylesheets during parsing
<!-- Please describe your changes on the following line: -->
Eagerly tokenize html input, and scan for `script` and `img` tags which can be prefetched into the cache. This allows resources to be loaded concurrently, which would otherwise be loaded sequentially due to being blocked by script execution. On the cloth webgl demo, this takes the time-to-paint down from 732ms to 560ms.
