Move ScriptToConstellationMsg to constellation_traits (#36364)
This is the last big change necessary to create the
`constellation_traits` crate. This moves the data structure for messages
that originate from the `ScriptThread` and are sent to the
`Contellation` to `constellation_traits`, effectively splitting
`script_traits` in half. Before, `script_traits` was responsible for
exposing the API of both the `ScriptThread` and the `Constellation` to
the rest of Servo.

- Data structures that are used by `ScriptToConstellationMsg` are moved
  to `constellation_traits`. The dependency graph looks a bit like this:
  `script_layout_interface` depends on `script_traits` depends on
  `constellation_traits` depends on `embedder_traits`.
- Data structures that are used in the embedding layer
  (`UntrustedNodeAddress`, `CompositorHitTestResult`, `TouchEventResult`
  and `AnimationState`) are moved to embedder_traits, to avoid a
  dependency cycle between `webrender_traits` and
  `constellation_traits`.
- Types dealing with MessagePorts and serialization are moved to
  `constellation_traits::message_port`.

Testing: This is covered by existing tests as it just moves types
around.

Make the memory reporting multi-process aware (#35863)
So far the memory reporter aggregates reports from all processes, and
runs the system reporter only in the main process. Instead it is
desirable to have per-process reports. We do so by:
- creating a ProcessReports struct that holds includes the pid in
addition to the reports themselves.
- running the system memory reporter also in content processes.
- updating the about:memory page to create one report per process, and
add useful information like the pid and the urls loaded in a given
process.

Check all ancestor navigable trustworthiness for mixed content (#36157)
Propagate through documents a flag that represents if any of the
ancestor navigables has a potentially trustworthy origin.

The "potentially trustworthy origin" concept appears to have gotten
confused in a couple of places and we were instead testing if a URL had
"potentially trustworthy" properties.

constellation: Only return focused browsing contexts that exist. (#36330)
The webdriver server relies on the constellation to report which
browsing context is focused, and assumes that a focused context is ready
for interaction. However, new browsing contexts exist in a weird state
where they are not tracked by the constellation until the initial load
is complete, which leads to the constellation rejecting attempts to
navigate a browsing context right after it's created. These changes
ensure the constellation does not report a browsing context as focused
until it's actually created and ready for interaction.

Testing: Run `./mach test-wpt --product servodriver
tests/wpt/mozilla/tests/mozilla/DOMParser.html`, which now runs to
completion.

constellation: Rename messages sent to the Constellation (#36341)
Messages that are sent to the `Constellation` have pretty ambiguous
names.
This change does two renames:

- `ConstellationMsg` → `EmbedderToConstellationMessage`
- `ScriptMsg` → `ScriptToConstellationMessage`

This naming reflects that the `Constellation` stands in between the
embedding layer and the script layer and can receive messages from both.
Soon both of these message types will live in `constellation_traits`,
reflecting the idea that the `_traits` variant for a crate is
responsible for exposing the API for that crate.

Testing: No new tests are necessary here as this just renames two enums.

Prevent zombie processes in multi-process mode. (#36329)
This introduces a process manager that holds for each process a
"lifeline": this is the receiving end of a ipc channel that is not used
to send anything, but only to monitor the process presence. We turn that
ipc receiver into a crossbeam one to integrate the monitoring into the
constellation run loop. The sender side is made part of the initial
"UnprivilegedContent" data structure sent to the new process, both for
content and for service worker processes.
When a process dies we currently wait() on it to let the OS do a clean
shutdown.

constellation: Stop assuming that the viewport is shared by all WebViews (#36312)
The `Constellation` previously held a `window_size` member, but this
assumes that all `WebView`s have the same size. This change removes that
assumption as well as making sure that all `WebView`s pass their size
and HiDIP scaling to the `Constellation` when they are created.

In addition

- `WindowSizeData` is renamed to `ViewportDetails`, as it was
holding more than just the size and it didn't necessarily correspond to
  a "window." It's used for tracking viewport data, whether for an
  `<iframe>` or the main `WebView` viewport.
- `ViewportDetails` is stored more consistently so that conceptually an
  `<iframe>` can also have its own HiDPI scaling. This isn't something
  we necessarily want, but it makes everything conceptually simpler.

The goal with this change is to work toward allowing per-`WebView` HiDPI
scaling and sizing. There are still some corresponding changes in the
compositor to make that happen, but they will in a subsequent change.

Testing: This is covered by existing tests. There should be no behavior
changes.
Fixes: This is part of #36232.

webgpu: Add a webgpu_traits crate (#36320)
This breaks the `script_traits` dependency  on `webgpu`. In general, the
`traits` crates shouldn't depend on Servo non-`traits` crates. This is
necessary to move "script to constellation" messages to the
`constellation_traits` crate, making it the entire API for talking to
the
constellation. This will break a circular dependency when that happens.

Testing: Successfully building is enough of a test for this one as
it is mainly moving types around.

libservo: Remove a couple EmbedderMethods (#36276)
- Remove `EmbedderMethods::get_user_agent_string`. This is now part of
  the `Preferences` data structure, which should allow it to be
  per-`WebView` in the future.
- Remove `EmbedderMethods::get_version_string`. This was used to include
  some data along with WebRender captures about the Servo version. This
  isn't really necessary and it was done to replace code in the past
  that output the WebRender version, so also isn't what the original
  code did. I think we can just remove this entirely.

The idea with these changes is that `EmbedderMethods` can be removed
in a followup and the rest of the methods can be added to
`ServoDelegate`. These two methods are ones that cannot be added to a
delegate as they are used during `Servo` initialization.

Testing: There is currently no testing for libservo. These changes are
meant
as preparation for adding a suite of `WebView` unit tests.

Create a constellation_traits crate (#36088)
This change creates a `constellation_traits` crate. Previously messages
to the `Constellation` were in the `compositing_traits` crate, which
came about organically. This change moves these to a new crate which
also contains data types that are used in both compositing/libservo and
script (ie types that cross the process boundary). The idea is similar
to `embedding_traits`, but this is meant for types not exposed to the
API.

This change allows deduplicating `UntrustedNodeAddress`, which
previously had two versions to avoid circular dependencies.

metrics: Simplify ProgressiveWebMetrics (#35985)
Simply how `ProgressiveWebMetrics` works:

1. Keep only a single struct instead of one in layout and one script
   that both implement the `ProgressiveWebMetrics` trait. Since layout
   and script are the same thread these can now just be a single
   `ProgressiveWebMetrics` struct stored in script.
2. Have the compositor be responsible for informing the Constellation
   (which informs the ScripThread) about paint metrics. This makes
   communication flow one way and removes one dependency between the
   compositor and script (of two).
3. All units tests are moved into the `metrics` crate itself since there
   is only one struct there now.

Add an about:memory page (#35728)
This patch exposes a servo internal DOM API that is only made available to about:
pages on the navigator object to request memory reports. The about:memory page itself is
loaded like other html resources (eg. bad cert, net error) and makes use of this new API.

On the implementation side, notable changes:
- components/script/routed_promise.rs abstracts the setup used to fulfill a promise when the
  work needs to be routed through the constellation. The goal is to migrate other similar
  promise APIs in followup (eg. dom/webgpu/gpu.rs, bluetooth.rs).
- a new message is added to request a report from the memory reporter, and the memory reporter
  creates a json representation of the set of memory reports.
- the post-processing of memory reports is done in Javascript in the about-memory.html page,
  providing the same results as the current Rust code that outputs to stdout. We can decide
  later if we want to remove the current output.

compositor: Make input event handling per-WebView (#35716)
This is another step in the move to having a per-WebView renderer. In
this step event handling is made per-WebView. Most events sent to Servo
are sent via the WebView API already, so this just moves more event
handling code to the per-WebView render portion of the compositor.

- ServoRenderer is given shared ownership and interior mutability as
  it is now shared among all WebView(Renderers).
- Some messages coming from other parts of Servo must now carry a
  WebViewId as well so that they can be associated with a particular
  WebView.
- There needs to be some reorganization of `ServoRenderer` in order to
  avoid issues with double borrow of `RefCells`.

This is one of the first big steps toward making the compositor work

This means that more messages need to carry information about the

need to map from `PipelineId` to `WebViewId`, so this also includes a
shared mapping which tracks this. The mapping can be removed once event
handling is fully per-WebView.

Make auxiliary webviews exist in the constellation immediately (#35672)
To allow embedders to interact with webviews as soon as they are
created, we need to ensure that they exist in both the compositor and
the constellation before those interactions happen. #35662 does this
for the compositor, while this patch does this for the constellation.

When a webview opens another webview (via <a target>, <form target>,
window.open(), etc), the embedder creates an “auxiliary” webview,
which previously went as follows:

- script create_auxiliary_browsing_context
- libservo AllowOpeningWebView
- embedder request_open_auxiliary_webview (→ constellation FocusWebView)
- script create_auxiliary_browsing_context
- constellation ScriptNewAuxiliary

In that model, the constellation may receive FocusWebView before it
receives ScriptNewAuxiliary. Now they are created as follows:

- script create_auxiliary_browsing_context
- constellation CreateAuxiliaryWebView
- libservo AllowOpeningWebView
- embedder request_open_auxiliary_webview (→ constellation FocusWebView)
- constellation CreateAuxiliaryWebView
- script create_auxiliary_browsing_context

Since these messages are all synchronous and the constellation will
have set up the webview before handling any new messages, the webview
will always exist by the time we handle the embedder’s FocusWebView.

libservo: Move WebDriver messages to the embedder crate (#35602)
This is the first step toward moving the WebDriver implementation to
servoshell. This move will make it possible to start testing the
embedding API with WebDriver. See [this zulip thread][a] for more details.

While WebDriver will be able to use a lot of API commands to do what it
is doing now, there will still need to be some "cheat codes" for more
gnarly access to `ScriptThread` details. That's why we likely won't be
able to remove all WebDriver-specific messages from the API -- but maybe
they will be useful for embedders somehow.

A couple messages have to change as they depended on `script_traits`
types, particularly those that used `WindowSizeData` and `LoadData`. I
think this helps to encapsulate the WebDriver commands a bit more
though.

compositing: Move image output and shutdown management out of the compositor (#35538)
This is a step toward the renderer-per-WebView goal. It moves various
details out of `IOCompositor`.

- Image output: This is moved to servoshell as now applications can
  access the image contents of a `WebView` via
  `RenderingContext::read_to_image`. Most options for this are moved to
  `ServoShellPreferences` apart from `wait_for_stable_image` as this
  requires a specific kind of coordination in the `ScriptThread` that is
  also very expensive. Instead, paint is now simply delayed until a
  stable image is reached and `WebView::paint()` returns a boolean.
  Maybe this can be revisited in the future.
- Shutdown: Shutdown is now managed by libservo itself. Shutdown state
  is shared between the compositor and `Servo` instance. In the future,
  this sharing might be unecessary.
- `CompositeTarget` has been removed entirely. This no longer needs to
   be passed when creating a Servo instance.

libservo: Move GL acclerated media setup out of RenderingContext and simplify it (#35553)
This moves the GL accelerated media setup out of `RenderingContext`
which prevents making libservo dependo on the Wayland and X11 versions
of surfman explicitly. This support is experimental and (honestly) a bit
broken. I've confirmed that this works as well as it did before the
change.

The main thing here is that the configuration, which currently needs
surfman types, moves to servoshell. In addition:

1. Instead of passing the information to the Constellation, the setup is
   stored statically. This is necessary to avoid introducing a
   dependency on `media` in `webrender_traits`. It's quite likely that
   `media` types should move to the internal embedding API to avoid
   this. This is preserved for a followup change.
2. The whole system of wrapping the media channels in an abstract type
   is removed. They could be either mpsc channels or IPC channels. This
   was never going to work because mpsc channels cannot be serialized
   and deserialized with serde. Instead this just uses IPC channels. We
   also have other ways of doing this kind of abstraction in Servo so we
   do not need another. The `mpsc` version was hard-coded to be
   disabled.

libservo: Expose a single InputEvent type and pass it to script (#35430)
This change exposes a single `InputEvent` type and now there is only a
single delegate method for this `WebViewDelegate::notify_input_event`.

- Clipboard events are now handled as `EditingAction` inpute events. In
  the future this can include things like "Select All", etc.

In addition, many parts of the dance to pass these events can now be
simplified due to this abstraction.

- All forwarded events are handled the same way in the `Constellation`,
  though they may carry an optional hit test (for events that have a
  `point`) which affects which `Pipeline` they are sent to.
- In the `ScriptThread` we now accept these `InputEvents` and use them
  everywhere. Now all "compositor events" are "input events".
- This allows removing several data structures which are no longer
  necessary.
- We no longer inform the embedder when an event was handled by a
  WebView as that was only important for a MDI feature that will
  no longer be so important the full-featured `WebView` API.

script_traits: Rename ConstellationControlMsg to ScriptThreadMessage (#35226)
At some point in the past this message was only sent from the
`Constellation` to `script`, but nowadays this is sent from various
parts of servo to the `ScriptThread`, so this is a better name. In
particular, the current name makes it seeem like this message controls
the `Constellation`, which it does not.

Include WebViewId into EmbedderMsg variants where possible (#35211)
`EmbedderMsg` was previously paired with an implicit
`Option<WebViewId>`, even though almost all variants were either always
`Some` or always `None`, depending on whether there was a `WebView
involved.

This patch adds the `WebViewId` to as many `EmbedderMsg` variants as
possible, so we can call their associated `WebView` delegate methods
without needing to check and unwrap the `Option`. In many cases, this
required more changes to plumb through the `WebViewId`.

Notably, all `Request`s now explicitly need a `WebView` or not, in order
to ensure that it is passed when appropriate.

libservo: Stop using script_traits in the embedding layer (#35185)
Many types used directly in the `libservo` API are in the
`script_traits` crate, which was created to break circular dependencies.
Move all API exposed types to `embedder_traits` which now contains types
exposed via the `libservo` embedding API. Also expose these at the root
of the `libservo` `servo` crate so that the API won't break when they
move around in the future.

The idea with `embedder_traits` in the future is that it contains types
that are available throughout servo because they are used in the
embedding API and thus should have minimal dependencies on other Servo
crates (a bit like `base`).

libservo: Add an initial WebView data structure to the API (#35119)
This patch introduces a new handle-based webview API to libservo, with
two main design goals:

1. The lifetime of the handles controls the lifetime of the webview,
   giving the embedder full control over exactly when webviews are
   created and destroyed. This is consistent with how WebKitGTK’s
   WebView works; the engine can only create webviews via a create
   request, and can only destroy them via a close request.
2. All methods are infallible; if the constellation dies, the embedder
   finds out when calling Servo::handle_events.

For the moment, the embedder is only responsible for creating the
WebView id, and not the internal TopLevelBrowsingContext data
structures. This is so that the ScriptThread is able to get a handle on
the new WebView's WindowProxy in the case that it's an auxiliary
browsing context. In the future, the embedder should also be responsible
for creating the TopLevelBrowsingContext and the ScriptThread should
have mechanism to associate the two views so that WebView creation is
always executed through the same code path in the embedding layer. For
now, it's enough that the embedder can get a handle to the new WebView
when it's creation is requested.

Once we replace EmbedderMsg with a webview delegate trait, we will pass
WebView handles to the embedder, rather than webview ids. We’ll also add
detailed docs, once the design settles.

api: Flatten and simplify Servo preferences (#34966)
Flatten and simplify Servo's preferences code. In addition, have both
preferences and options passed in as arguments to `Servo::new()` and
make sure not to use the globally set preferences in `servoshell` (as
much as possible now).

Instead of a complex procedural macro to generate preferences, just
expose a very simple derive macro that adds string based getters and
setters.

- All command-line parsing is moved to servoshell.
- There is no longer the concept of a missing preference.
- Preferences no longer have to be part of the resources bundle because
  they now have reasonable default values.
- servoshell specific preferences are no longer part of the preferences
  exposed by the Servo API.

script: Move navigation fetching to the ScriptThread (#34919)
This allows reusing the asynchrnous fetch mechanism that we use for page
resources and is likely a step toward removing the `FetchThread`.

Benefits:
 - Reduces IPC traffic during navigation. Now instead of bouncing
   between the constellation and the `ScriptThread` responses are sent
   directly to the `ScriptThread`.
 - Allows cancelling loads after redirects, which was not possible
   before.

There is the question of what to do when a redirect is cross-origin
(#23037). This currently isn't handled properly as the `Constellation`
sends data to the same `Pipeline` that initiated the load. This change
doesn't fix this issue, but does make it more possible for the
`ScriptThread` to shut down the pipeline and ask the `Constellation` to
replace it with a new one.

script: Make timers per-process (#34581)
Before all timers were managed by the Constellation process, meaning
that they had to trigger IPC calls to be scheduled and fired. Currently,
timers are only used in the `ScriptThread`, so it makes sense that they
are per-process.

This change restores the timer thread functionality that existed before
avoided entirely. Completion is done using a callback that is sent to
the timer thread similarly to how fetch is done. This allows reusing the
existing task queue without making any new channels.

Fixes #15219.
