We can use stable rust if we pass the unstable configuration as
command-line arguments to rustfmt itself. This prevents needing to
install an unstable rust toolchain.
The one downside here is that it doesn't seem that "ignore" is
supported so we have to start formatting the files in "third_party."
This shouldn't be a huge issue because we don't plan to check much more
rust code into those directories.
* 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.

* impl From<&CompositorEvent> for CompositorEventVariant
* remove msg temporaries in Constellation::forward_event
* use single wildcard arm in EventDelivered case in handle_servo_events
The constellation forwards messages from other tasks to the compositor.
Mainly, these are passed to WebRender. This change updates the names of

they are going.

This slightly expands text boundaries in order to take into account the
fact that layout isn't measuring glyph boundaries.

* check in resources/crash.html

* fmt + tidy

* clean up crash page and add details (reason + backtrace)
* avoid repeating crash errors in script::script_thread warn log
* make new LoadData init more idiomatic
* clarify comments and new fields
* fix doc comment style
* Fix `mach test-wpt` to make crash tests work
There are two issues related to crash tests:
1. test-wpt is unable to find existing crash tests even when
called with --test-types=crashtests. The fix here is to
add crashtests to the default test suite types to python/wpt/run.py
2. When running in headless mode, crashes in style threads
don't cause servo to crash because the logic in constellation.rs
currently calls handle_panic only when the top-level browsing
context id is some value. Since style pool threads are shared,
they always generate Panic messages with None as top-level
browsing context id.

* Send bactrace to stderr and capture it in test runner
Servo's panic hook writes backtraces to stdout. This
patch changes it so they are written to stderr.
The crash test executor for servo in WPT grouping formatter
was also not capturing the output correctly for crashtests
as the log events were being aggregated based on thread name
which doesn't seem to match correctly in case of crashtests.
This patch also fixes the log grouping logic to be based on
test name.

This also removes the meta viewport support (which was implemented on top), but that also had a single test and is disabled everywhere, so I'm not too concerned, it can be implemented again if / when needed.
Constellation seems to have lots of code that could be moved into
seperate files. `FromScriptLogger` and `FromCompositorLogger` seem
to qualify for that.
Moved FromScriptLogger and FromScriptLogger to logger file.
This change adds support for the <iframe> element to Layout 2020. In
addition, certain aspects of the implementation are made the same
between both layout systems.

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.
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.
