This is preparation for sharing this code with layout_2020 and
implementing selective off-the-main-thread animations.
We still look for nodes not in the flow tree in the layout thread.
The image cache returns an `ImageCacheResult::ImageAvailable `the second
time you try getting the placeholder. This means that in some cases, the
loading of an image would fail, then the same image would get fetched
from the cache, the placeholder would be loaded from that but would be
seen as a normal image, firing a load event.
This made the tests in
`fetch/cross-origin-resource-policy/image-loads.html` fail depending on
their order.
Add referrerpolicy to list of relevant mutations
<!-- Please describe your changes on the following line: -->
`img.referrerPolicy` change now mutates the image.
Not all `referrerPolicy` attribute changes result in an image update event.
Only valid changes are reflected.
All referrerpolicy tests inside `relevant-mutations.html` WPT test now pass.

This fixes#26388. referrerPolicy is now calls onload for image
mutations. Not all referrerPolicy attribute changes result in an image
update event. Only valid changes are reflected.
Referrerpolicy tests now pass.
Have animations more closely match the HTML spec
These two commits do two major things:
**Have animations ticks trigger a restyle**: This corrects synchronization issues with animations,
where the values used in layout are out of sync with what is returned by `getComputedStyle`.
**Tick the animation timer in script according to spec**: This greatly reduces the flakiness of
animation and transitions tests.
Fixes#13865.

This doesn't change any expectation because we're not setting
response.redirected properly so all the tests fail later on when it's
asserted to be true.
Fixes#25257
This is a small step toward fixing #19242. The main idea is that the
clock for animations should advance as the event loop ticks. We
accomplish this by moving the clock from layout and naming it the
"animation timeline" which is the spec language. This should fix
flakiness with animations and transitions tests where a reflow could
move animations forward while script was running.
This change also starts to break out transition and animation events
into their own data structure, because it's quite likely that the next
step in fixing #19242 is to no longer send these events through a
channel.
This change corrects synchronization issues with animations, by
reworking the animation processing model to do a quick restyle and
incremental layout when ticking animations.
While this change adds overhead to animation ticks, the idea is that
this will be the fallback when synchronous behavior is required to
fulfill specification requirements. In the optimistic case, many
animations could be updated and applied off-the-main-thread and then
resynchronized when style information is queried by script.
Fixes#13865.

Add a fast path in Element::SetInnerHTML when the value is small and trivial text
Inspired from gecko which has a similar fast path. This makes innerHTML
more than 10 times faster for this case.
Fixes#25892
Gstreamer backend returns channel as single bit mask (ie 1, 2, 4, 8, 32 etc).
Progress callback was using this mask as plain channel index, thus storing decoded
audio in wrong channel.
Add support for WebGL2 MIN_PROGRAM_TEXEL_OFFSET
Improves the support of the WebGL2 `MIN_PROGRAM_TEXEL_OFFSET` property (ie. stores it as a signed integer) and adds support for querying it using GetParameter.

This is triggered when an animation finishes. This is a high priority
because it allows us to start rooting nodes with animations in the
script thread.
This doesn't yet cause a lot of tests to pass because they rely on the
existence of `Document.getAnimations()` and the presence of
`animationstart` and animationiteration` events.

Add support for some more WebGL2 limit parameters
Adds support for the following new WebGL2 GetParameter values:
- `MAX_ELEMENT_INDEX`
- `MAX_ELEMENTS_INDICES`
- `MAX_ELEMENTS_VERTICES`
- `MAX_FRAGMENT_INPUT_COMPONENTS`
- `MAX_SAMPLES`
- `MAX_SERVER_WAIT_TIMEOUT`
- `MAX_TEXTURE_LOD_BIAS`
- `MAX_VARYING_COMPONENTS`
- `MAX_VERTEX_OUTPUT_COMPONENTS`

Improve devtools output for console APIs
These changes use the new API from https://github.com/servo/rust-mozjs/pull/508 to report meaningful filenames and line numbers for APIs that trigger devtools output. They also cause error messages originating from uncompiled event handlers to report a more relevant filename; this differs from Gecko's behaviour, but provides a more useful debugging experience in my opinion.

- [x] `./mach build -d` does not report any errors

- [x] These changes fix#9604 and fix#26344.
- [x] These changes do not require tests because devtools aren't tested.
Improve devtools experience when navigating
The primary motivation for this work was to fix#15425, and these changes make it possible to use the devtools to meaningfully inspect multiple pages when navigating between them. Navigating through session history is not yet supported.
These changes also include improvements to the dedicated worker support, which broke at some point. We now can observe console messages in workers.
Add support for WebGL2 buffer types in GetBufferParameter
This makes the new buffer types introduced in WebGL2 usable by the GetBufferParameter call.

Break the association between pipelines and browsing context actors.
Now there is one browsing context actor per actual browsing context,
and individual actors keep track of known pipelines as necessary.
There is also one console/performance/timeline/inspector/etc. actor
per browsing context.
This also centralizes more information in the browsing context actor.
Rather than duplicating state for the active pipeline in actors that
need to use it, each actor now remembers the name of its associated
browsing context actor and obtains that state whenever it's necessary.
Add support for transitionrun events
These events are triggered as soon as a transition is added to the list
of running transitions. This will allow better test coverage while
reworking the transitions and animations processing model.
