script: Do not set up an IPC route for every image load (#35041)
Instead of setting up a route for every image load in the DOM / Layout,
route all incoming image cache responses through the `ScriptThread`.
This avoids creating a set of file descriptor for every image that is
loaded.

This change requires having the `ImageCache` track the `PipelineId` of
the original the listener so that the `ScriptThread` can route it
properly to the correct `Window`.

layout: Remove the obsolete layout tracing functionality (#35001)
There were two kinds of layout tracing controlled by the same debugging
option:

 - modern layout: Functionality that dumped a JSON serialization of the
   layout tree before and after layout.
 - legacy layout: A scope based tracing that reported the process of
   layout in a structured way.

I don't think anyone working on layout is using either of these two
features. For modern layout requiring data structure to implement
`serde` serialization is incredibly inconvenient and also generates a
lot of extra code.

We also have a more modern tracing functionality based on perfetto that
we have started to use for layout and IMO it's actually being used and
more robust.

layout_2013: Remove code preventing writing mode assertion failures (#32698)
It's actually kind of useful that this code crashes, as it points out a

base: Remove ucd dependency (#32424)
Remove the `ucd` dependency which has not been updated in 8 years. In
addition, replace it with a generated UnicodeBlock enum which reflects
the modern Unicode standard. This is generated via a Python script which
is included in the repository. The generation is not part of the build
process, because the Unicode database is hosted on the web and it does
not change the frequently.

This is done instead of bringing in the more up-to-date `unicode_blocks`
dependency. `unicode_blocks` defines each block as constant, which means
that they cannot be used in match statements -- which we do in Servo.

layout: Add support for white-space-collapse: break-spaces (#32388)
This change adds support for `white-space-collapse: break-spaces` and
adds initial parsing support for `overflow-wrap` and `word-break`. The
later two properties are not fully supported, only in their interaction
with `break-spaces`. This is a preliminary change preparing to implement
them.

In addition, `break_and_shape` is now forked and added to Layout 2020.
This function is going to change a lot soon and forking is preparation
for this. More code that is only used by Layout 2013 is moved from `gfx`
to that crate.

Move non-gfx things out of gfx_traits and create a base crate (#32296)
For a long time, `gfx_traits` has held a lot of things unrelated to graphics
and also unrelated to the `gfx` crate (which is mostly about fonts).
This is a cleanup which does a few things:

1. Move non `gfx` crate things out of `gfx_traits`. This is important in
   order to prevent dependency cycles with a different integration between
   layout, script, and fonts.
2. Rename the `msg` crate to `base`. It didn't really contain anything
   to do with messages and instead mostly holds ids, which are used
   across many different crates in Servo. This new crate will hold the
   *rare* data types that are widely used.

Details:

 - All BackgroundHangMonitor-related things from base to a new
   `background_hang_monitor_api` crate.
 - Moved `TraversalDirection` to `script_traits`
 - Moved `Epoch`-related things from `gfx_traits` to `base`.
 - Moved `PrintTree` to base. This should be widely useful in Servo.
 - Moved `WebrenderApi` from `base` to `webrender_traits` and renamed it
   to `WebRenderFontApi`.

fonts: Make FontContext thread-safe and share it per-Layout (#32205)
This allows sharing font templates, fonts, and platform fonts across
layout threads. It's the first step toward storing web fonts in the
layout versus the shared `FontCacheThread`. Now fonts and font groups
have some locking (especially on FreeType), which will probably affect
performance. On the other hand, we measured memory usage and this saves
roughly 40 megabytes of memory when loading servo.org based on data from
the memory profiler.

Turn white-space into a shorthand (#32146)
Bumps Stylo to servo/stylo#37

`white-space` is split into `white-space-collapse` and `text-wrap-mode`:

| white-space | white-space-collapse | text-wrap-mode |
| ----------- | -------------------- | -------------- |
| normal      | collapse             | wrap           |
| nowrap      | collapse             | nowrap         |
| pre-wrap    | preserve             | wrap           |
| pre         | preserve             | nowrap         |
| pre-line    | preserve-breaks      | wrap           |
| -           | preserve-breaks      | nowrap         |

Note this introduces a combination that wasn't previously possible,
but I think the existing logic can handle it well enough.

The old `allow_wrap()` is replaced by checking whether `text-wrap-mode`
is set to `wrap`.

The old `preserve_newlines()` is replaced by checking whether
`white-space-collapse` is *not* set to `collapse`.

The old `preserve_spaces()` is replaced by checking whether
`white-space-collapse` is set to `preserve`.

script: Do not run layout in a thread (#31346)
* script: Do not run layout in a thread

Instead of spawning a thread for layout that almost always runs
synchronously with script, simply run layout in the script thread.

This is a resurrection of #28708, taking just the bits that remove the
layout thread. It's a complex change and thus is just a first step
toward cleaning up the interface between script and layout. Messages are
still passed from script to layout via a `process()` method and script
proxies some messages to layout from other threads as well.

Big changes:

1. Layout is created in the script thread on Document load, thus every
   live document is guaranteed to have a layout. This isn't completely
   hidden in the interface, but we can safely `unwrap()` on a Document's
   layout.
2. Layout configuration is abstracted away into a LayoutConfig struct
   and the LayoutFactory is a struct passed around by the Constellation.
   This is to avoid having to monomorphize the entire script thread
   for each layout.
3. Instead of having the Constellation block on the layout thread to
   figure out the current epoch and whether there are pending web fonts
   loading, updates are sent synchronously to the Constellation when
   rendering to a screenshot. This practically only used by the WPT.

A couple tests start to fail, which is probably inevitable since removing
the layout thread has introduced timing changes in "exit after load" and
screenshot behavior.

Backport several style changes from Gecko (5) (#30099)
* style: Simplify selector flag setting now that flag setting is atomic

These bits are write-only, actually, and we don't even need to read
them.

Differential Revision: https://phabricator.services.mozilla.com/D141888

* Further changes required by Servo

* style: Support media queries for dynamic-range and video-dynamic-range

This is a stub that only matches "standard" for all platforms.

Differential Revision: https://phabricator.services.mozilla.com/D141053

* style: Remove :-moz-lwtheme-{brighttext,darktext}

They are just convenience for :root[lwthemetextcolor="light"] (and dark,
respectively), but they generally shouldn't be used for dark mode
theming. In the past it was the only way to do it but now we have
prefers-color-scheme.

While at it, change lwthemetextcolor to be "lwtheme-brighttext" for
consistency with similar code we have for popups etc, and move it to
_setDarkModeAttributes.

While at it, remove layout.css.moz-lwtheme.content.enabled (which is
false always, we unshipped these from content successfully).

Differential Revision: https://phabricator.services.mozilla.com/D141593

* style: layout.css.moz-locale-dir.content.enabled

We successfully removed these from content in bug 1740230 (Firefox 96).

Differential Revision: https://phabricator.services.mozilla.com/D141727

* style: Really honor background-color: transparent in HCM even for form controls

I forgot we were doing this "revert-or-initial" shenanigans (which is needed
for stuff like link colors to be honored), so we need to early-return.

Use a more explicit test rather than a reftest for this.

Differential Revision: https://phabricator.services.mozilla.com/D142063

* style: Ignore unchanged property for scroll-linked effect detector

I think this is cleaner.

Differential Revision: https://phabricator.services.mozilla.com/D141737

* style: Allow to derive Parse/ToCss/SpecifiedValueInfo on bitflags

We keep getting this pattern of properties that have a set of joint and
disjoint flags, and copy-pasting or writing the same parsing and
serialization code in slightly different ways.

container-type is one such type, and I think we should have a single way
of dealing with this, thus implement deriving for various traits for
bitflags, with an attribute that says which flags are single vs mixed.

See docs and properties I ported. The remaining ones I left TODOs with,
they are a bit trickier but can be ported with some care.

Differential Revision: https://phabricator.services.mozilla.com/D142418

* Further changes required by Servo

* style: Implement parsing / serialization for container{,-type,-name} CSS properties

Two noteworthy details that may seem random otherwise:

 * Moving values around in nsStyleDisplay is needed so that the struct
   remains under the size limit that we have to avoid jumping allocator
   buckets.

 * All the test expectation churn is because tests depend on
   `container-type: size` parsing to run, and now they run. Tests for
   the relevant bits I implemented are passing, with the only exception
   of some `container-name-computed.html` failures which are
   https://github.com/w3c/csswg-drafts/issues/7181. Safari agrees with
   us there.

Other notes when looking at the spec and seeing how it matches the
implementation:

 * `container` syntax doesn't match spec, but matches tests and sanity:
   https://github.com/w3c/csswg-drafts/issues/7180

 * `container-type` syntax doesn't _quite_ match spec, but matches tests
   and I think it's a spec bug since the definition for the missing
   keyword is gone:
   https://github.com/w3c/csswg-drafts/issues/7179

Differential Revision: https://phabricator.services.mozilla.com/D142419

* style: Remove assert that doesn't hold for text-decorations because of presentation hints

MANUAL PUSH: Orange fix CLOSED TREE

* style: Migrate `<th>` `text-align` behaviour from presentation hint to UA CSS

Differential Revision: https://phabricator.services.mozilla.com/D142494

* style: Deduplicate TokenList values faster

Remember whether we have already de-duplicated them once and avoid doing
that again.

This is an alternative approach that doesn't add overhead to attribute
setting in the general case.

Differential Revision: https://phabricator.services.mozilla.com/D142813

* style: Inherit used color-scheme from embedder <browser> elements

This allows popups and sidebars to use the chrome preferred
color-scheme.

This moves the responsibility of setting the content-preferred color
scheme to the appropriate browsers to the front-end (via tabs.css).

We still return the PreferredColorSchemeForContent() when there's no
pres context (e.g., for display:none in-process iframes). We could
potentially move a bunch of the pres-context data to the document
instead, but that should be acceptable IMO as for general web content
there's no behavior change in any case.

Differential Revision: https://phabricator.services.mozilla.com/D142578

* Further changes required by Servo

* style: Add basic @container rule parsing and boilerplate

For now parse a MediaFeatureCondition. That needs being made more
specific, but that is probably worth its own patch.

Differential Revision: https://phabricator.services.mozilla.com/D143192

* Further changes required by Servo

* style: Tweak cascade priority to split writing-mode and font properties

This makes the worst case for cascade performance slightly more
expensive (4 rather than three declaration walks), but my hope is that
it will make the average case faster, since the best case is now just
two walks instead of three, and writing mode properties are somewhat
rare.

This needs a test, but needs to wait until the writing-mode dependent
viewport units land (will wait to land with a test).

* style: Fix visited handling after bug 1763750

Before bug 1763750, we unconditionally called compute_writing_mode,
which got the writing mode from the cascade mode for visited styles.

However after that bug we only do that if we apply any
writing-mode-related property.

We could just call compute_writing_mode unconditionally, but instead it
seems better to skip all that work for visited cascade and reuse the
mechanism introduced in that bug to only apply the visited-dependent
longhands.

We assert that all visited-dependent longhands are "late" longhands, so
as to also avoid applying the font group and such.

* style: Simplify media query evaluation code a bit

This patch:

  * Removes generic <ident> support for media features. These were used
    for some privileged media features but are no longer used.

  * Simplifies media feature getters by shifting the responsibility of
    dealing with RangeOrOperator to the caller. This makes it easier to
    implement container-query / mediaqueries-4 syntax, and also cleans up
    the code a bunch.

There should be no change in behavior.

* Further changes required by Servo

* style: Move transitions and animations to nsStyleUIReset

This mostly just moves code around, to minimize potential behavior
changes. There are some cleanups that we should try to do long term
(this "have an array with n different counts" is pretty weird).

But for now this should unblock people.

The destination struct (nsStyleUIReset) was chosen mainly because it's
small and non-inherited, and it doesn't seem like a worse place than
nsStyleDisplay.

* Further changes required by Servo

* style: Make media feature evaluation take a computed::Context

This has no behavior change right now, but will simplify sharing code
with container queries.

Container queries will have container information in the
computed::Context (this is necessary anyways for container-based units),
so this avoids having to have different code for media and container
queries.

* style: Add scroll() to animation-timeline for style system

scroll() is defined in the spec proposal, and there is a temporary spec:
https://drafts.csswg.org/scroll-animations-1/rewrite#scroll-notation.

The spec is still under development, so we don't drop the orignal
scroll-timeline at rule. Instead, we add a new scroll() notation to
animation-timeline, and support both syntax for now.

Differential Revision: https://phabricator.services.mozilla.com/D143417

* style: Tweak contain bitflag definition order to avoid static constructors

This has no behavior change otherwise. The STRICT definition depended on
SIZE, which was defined later. That's fine in Rust, but in C++ it causes
the initialization to be dynamic because it doesn't have the definition
of SIZE yet (ugh).

This is the fix for the regression, though the following patch turns on
constexpr support in cbindgen, which would've caught this at build-time,
and guarantees that we don't have extra static constructors.

Differential Revision: https://phabricator.services.mozilla.com/D144316

* style: Move some of the media query code to a more generic queries module

No behavior change, just moving and renaming files.

The code in the "queries" module will be shared between @media and
@container.

@media has some other code that container queries doesn't need like
MediaList / MediaType / etc. That remains in the media_queries module.

* style: Simplify selector flags setup even more

In my investigation for bug 1766439, I am digging into why selector
matching regressed.

It doesn't help that the selector-matching code is instantiated a
gazillion times (so there's a ton of copies of the relevant functions).

This was needed in the past because we had different ways of setting the
selector flags on elements, but I unified that recently and now we only
need to either set them or not. That is the kind of thing that
MatchingContext is really good for, so pass that instead on
MatchingContext creation.

* style: Track @container condition id in style rules

Much like we track layer rules. Consolidate that "containing rule state
we pass down while building the cascade data" in a single struct that we
can easily restore.

For now, do nothing with it. I want to land this patch separately
because it touches the Rule struct and CascadeData rebuilds, which both
are performance sensitive.

Its layout shouldn't change because I also changed LayerId to be a u16
(this shouldn't matter in practice, since LayerOrder is already a u16).

After bug 1768278 and bug 1767815 there's no more uses of the cliprounded value
in the tree (also it causes artifacts on HiDPI screens so we probably don't
want new usages).

The "sheet" value is unused, and the other values other than "default" and
"none" are only derived from "default", so they don't need to be exposed in the
style system.

* style: More container queries plumbing

Provide container information in computed::Context and use it to resolve

expected.

This reuses our existing undisplayed style generation, but in a

much more often.

This brings the test-case in the bug to par with other browsers or
better, and is much simpler than the initial approach I tried back in
the day.

72302e2dae Detect body elements during layout
During layout it is often useful, for various specification reasons, to
know if an element is the `<body>` element of an `<html>` element root. There
are a couple places where a brittle heuristic is used to detect `<body>`
elements. This information is going to be even more important to
properly handle `<html>` elements that inherit their overflow property from
their `<body>` children.

Implementing this properly requires updating the DOM wrapper interface.
This check does reach up to the parent of thread-safe nodes, but this is
essentially the same kind of operation that `parent_style()` does, so is
ostensibly safe.

This change should not change any behavior and is just a preparation
step for properly handle `<body>` overflow.

- Update lyon_geom to the latest version

Major change:

- All matrices are now stored in row major order. This means that
  parameters to rotation functions no longer should be negated.
- `post_...()` functions are now named `then()`. `pre_transform()` is removed,
  so `then()` is used and the order of operations changed.

The image cache returns an `ImageCacheResult::ImageAvailable `the second
