So that sheets are properly marked as committed. The issue is that we
have this "committed" optimization, to avoid doing work if somebody adds
and removes an stylesheet without us flushing in the meantime:
https://searchfox.org/mozilla-central/rev/f018480dfed4fc583703a5770a6db9ab9dc0fb99/servo/components/style/stylesheet_set.rs#308-319
The "committed" bit is set when we consume the flusher (in each(..)).
However when we hit the cache, before this patch, we wouldn't consume
it, which means that we may fail to do some full rebuilds even though we
need them.
Fix it by making sure we call each() in that case.
We add a test (the test would show a red square before this patch, and a
lime square with the fix).

This will allow detecting the system theme, which allows fixing some of
the blocked bugs.
Note that when using the system theme we will still match light or dark
appropriately, so this shouldn't change behavior just yet.

We had about 9 gaps / unused bits. I moved the devtools ones at the end
because I think we should be able to remove them (but separate bug).

We should just restore the state when seeing whitespace and an unknown
token like when we do when finding any other token a few lines below.
This is not an issue for most callers (it's only an issue for clamp())
because the other callers use either `parse_comma_separated()` (for
min/max), or `parse_nested_block()` (for parens / nested calc()).
Both of those functions restrict the input in such a way that
is_exhausted returns true (a few lines above) and thus we parse
successfully.

This adds a new @media query -moz-toolbar-prefers-color-scheme which works like
prefers-color-scheme but is set based on the browser theme rather than the OS
theme. The background colour of the toolbar is used to determine the theme
dark/light preference. This will be used for in-content common.css pages and
other UI elements that include that stylesheet in the browser-chrome through
shadow DOM.
The end result is that about: pages, infobars, and modals will now "match" the
browser theme (just light/dark mode, not LWT theming support).

Make `Location` operate on the correct objects
This PR updates the implementation of the "[`Location`-object navigate][1]" algorithm to use the correct browsing context as the source browsing context for navigation. This affects the determination of a referrer and referrer policy and the treatment of `javascript:` URLs.
This PR also fixes the derivation of a `Location` object's [relevant `Document`][2] to match the specified behavior.

Start the transition to workspace dependencies
This will ultimately make it simpler to update crate dependencies and reduce duplication when specifying requirements. Generally, this change does not touch dependencies that are only used by a single crate. We could consider moving them to workspace dependencies in the future.

This change refactors how layout is done in Layout 2020 in preparation
for a compositor-side scroll tree:
1. Now the SpatialId and ClipId of each fragment is stored separately.
This will allow storing a scroll node id instead of only the handle
to the WebRender spatial node.
2. Separate out stacking context tree construction and display list
building. This change will make it possible to eventually build the
stacking context tree without the full display list if we find that
necessary. For instance, this might be useful to cache containing
block boundaries.
3. Add a `DisplayList` struct that stores both the WebRender display
list builder and the compositor info. This exposes the API to the
layout thread for display list building.
In addition, this change adds a lot of missing documentation. This
should not change behavior.
This property does nothing since bug 315209 got implemented.
Every single user that I checked was doing the same math by hand, so
hooray for good defaults :-)

Safari does this. This reduces the runtime in the example linked from
comment 0 quite a lot (40ms on a local opt build, from ~130ms on a
release nightly build).
I added a pref because there's a slight chance of performance
regressions on pages that do not use attribute selectors, as we're now
doing more unconditional work per element (adding the attributes to the
bloom filter). But the trade-off should be worth it, I think.

No behavior change, just cleanup. Actually seem this technically _adds_ some code even
though it's a cleanup, but that's mostly because of the wrapping of the
derive list. The resulting code is simpler (more in-line with our usual
things, so I think it's an improvement).

Similifies use of EventStates and ObjectType/FallbackType enums since most states they represented are no longer valid with the removal of NPAPI plugins. The state machine for (unsupported) plugin elements is now much simpler but still distinguishes between HTML fallbacks, fallbacks leading to a "BROKEN" state (e.g. failing to load the image the element refers to), and fallbacks that would simply lead the element to occupy an empty region. The last type of fallback is behind a pref "layout.use-plugin-fallback" and is disabled by default.
Simplifying the state machine allows us to clean up nsObjectLoadingContent. We also update many of the enums which refered to plugins, which would otherwise get confusing.

There's no reason we can't just query LookAndFeel and we need to use
sSystemMetrics. In the past, LookAndFeel queries were not cached, but
this is no longer the case, so perf wise should be pretty equivalent.
Note that we don't need the NS_SUCCEEDED checks because the default
value from GetInt if the platform doesn't support it is 0 anyways.

This parsing is hidden behind the pref layout.css.page-size.enabled.
It isn't ideal that we parse this as a property, but we can't treat it as a
descriptor because of compatibility issues with other browsers. There are also
outstanding spec issues related to how descriptors like page-size are cascaded,
and whether the !important specifier is valid or not.
