Since indexeddb is now part of the experimental features list, we can

In preparation for the next release, bump the version number to 0.1. 0.1
will be an LTS release, which receives extended support in terms of
security updates (e.g. spidermonkey security updates). Please keep in
mind that as always no specific guarantees or response times are given,
and any updated are provided on a best effort basis.
Previously some projects had a demo integration of servo based on some
version of servo, and then never or rarely updated it. Providing an LTS
release offers an option to embedders to integrate servo, while reducing
API churn and having a somewhat fixed schedule to adhere to in terms of
upgrades. Currently, the plan is for a new LTS release every 6 months,
with additional documentation regarding API changes and recommended
migration patterns (best-effort and subject to change).
Testing: No functional changes. Additional testing will be performed
post-merge on the newly created release branch.

This PR considers the following constraints:
- Resources must be available when building servo via a published
crates.io package (i.e. no `../../../resources/<file>` file references).
- Minimal setup when writing tests (`nextest` spawns each test in its
own process, so we don't want to explicitly initialize the resource
handler for every `#[test]` fn)
- Use local resources when developing locally
- Support loading the resources from a proper resource directory if the
embedder wishes so, including via a custom mechanism, not necessarily as
files
(File) Resources that are only accessed from servoshell are out of scope
of this PR, since it mainly focusses on unblocking publishing `libservo`
to crates.io.
Baking the resources into the binary by default simplifies the setup a
lot. We already supported that before, but only for testing purposes and
explicitly not for production builds.
Using [`inventory`](https://crates.io/crates/inventory) adds a simple
way for the embedder to replace the default baked in resources, while
also keeping the test usage of baked in resources simple.
rippy.png is also referenced from image_cache - We simply duplicate it,
since the image is small, to avoid adding unnecessarily complex
solutions like adding a dedicated crate.

This change adds support for a blinking text caret using WebRender
`DynamicProperties` updates. This ensures that text caret updates are as
lightweight as possible. As part of this change, the initial framework
for paint-side animations is added. Though this is driven by a timer for
now (in order to not have to run full speed animations for text carets),
the idea is that more animations can be driven by `Paint` in the future
(in order to avoid doing layouts during animations).
In addition, a preference is added which controls the caret blink speed.
This is used to disable caret blinking during WPT testing.
Testing: There are no tests for this change. We do not currently have a
good
way to test caret blinking as the caret is render only and fully testing
blinking would require well timed screenshot creation.

We need a map between frame actor ids (from devtools) and frame objects
(from debugger.js) to implement stepping hooks in the future.
To achieve this, we register the frame actor with a call to the devtools
before entering the event loop when the debugger is paused. Instead of
creating the frame actor in `handle_debugger_pause`, we create it
before.

Remove the placeholder way of getting a debuggee in `eval` and finds the
correct one in the map. Another way of doing this would be to have two
maps, `debuggeesToPipelineIds` and `pipelineIdsToDebuggees`, I'm open to
both approaches. I think this might be fine since the reverse operation
is only used here, but if it becomes a performance issue we can change
it.

The pause debugger screen should be shown for both pausing manually
(interrupt) and hitting a breakpoint.
Reuse the logic for pausing breakpoints to pause the debugger when the
user manually clicks the pause button.
Rename the pause event to interrupt to match the language of the
DevTools client and to avoid confusion with paused frames, which can
happen on interrupt or on a breakpoint.

Similar to about:config from firefox. All preferences are editable;
editing them mid-runtime is not guaranteed to cause any effects. This is
separate from servo:preferences, which selectively groups and exposes
preferences. This probably would become more useful if/when preferences
become persistent.

Followup work:
- Remove `getStringPreference`, `getIntPreference`, and
`getBoolPreference`. Using `getPreference` and `preferenceType` is more
flexible.
- Make more of these config options work on the fly.
- Allow for reverting config options.

This version bump is a bit delayed, since I forgot to open the PR before
FOSDEM. The actual release will thus likely not be based on this commit,
but backported to the release branch, to stay in sync with our monthly

There still has been no resolution on the `0.1` version bump situation,
hence another bump of the patch version.

The test harness attempts to reset preferences to default values when
running a test in which previously-set preferences are no longer set.
This leads to confusing interactions with any preference customizations
that are present, such as `--pref whatever` or `--prefs-file
something.json`, which are not considered when calculating the default.
This PR changes that: whatever preference values are present when the
webdriver server starts is treated as the default value.
Testing: This is a servo-specific webdriver extension, and we're fixing
an interaction with the test harness. I don't see another way to test
this besides observing the impact on our test results.

Add an event listener for `pause` to `debugger.js` and the necessary
glue to access it from the `devtools` crate. This returns important
information to know where we are paused, such as the source location and
frame state.
Fix frame and object actor encoding into messages. Use information from
`debugger.js` to correctly fill the fields.
Add a new `frames` list to the thread actor and handle the `frames`
message.
Fix `getEnvironment` reply in the frame actor. It is out of form (has a
`type` field but it doesn't require a followup empty message, it already
counts as a reply), so we need to handle it specially.
Note: For now we are focusing on the protocol side of the debugger, and
this patch only shows where the pause would happen. Pausing Servo itself
will happen in a followup.
Testing: `mach test-devtools` and manual testing. No errors (apart from
#42006).

Since this interface's is not accurate and couldn't fulfill it's

been integrated with `PinchZoom`, viewport resizing, and viewport
scroll.

Instead of having the `ImageCache` return the broken image icon for
failed loads, have `HTMLImageElement` explicitly request it. This means
that the image is loaded on demand (reducing the usage of resources) and
also simplifying the interface of the `ImageCache` greatly.
In addition, the display of the broken image icon is improved, more
closely matching other browsers. A test for this display (which was
falsely passing before) is updated to reflect the new display of the
broken image icon.
Testing: There is a Servo-specific test for this change. Some WPT tests
start to fail as well. Before these were not properly loading the broken
image icon so they were failing before, just in a hidden way.
