This changes font-family storage to reuse the rust types, removing a
bunch of code while at it. This allows us to, for example, use a single
static font family for -moz-bullet and clone it, rather than creating a
lot of expensive copies.

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.

Implement an observer to wait for correct window events in order to restore tab
content. Non-SHIP code restores about:reader scroll position after receiving
"AboutReaderContentReady" event, so to achieve the same thing with session
history in parent enabled, we can wait for "AboutReader:Ready" event.

The SpinEventLoopUntilOrShutdown is interrupted in the main process only at stage "xpcom-shutdown", which is too late. In a content process instead we interrupt it early enough, at "content-child-will-shutdown".
This patch removes the current observer logic in nsThreadManager in favor of a current shutdown phase state machinery in AppShutdown and renames SpinEventLoopUntilOrShutdown to SpinEventLoopUntilOrQuit. It also ensures that SpinEventLoopUntilOrQuit breaks early (at "quit-application" in the main process).
For a further possible cleanup around shutdown state in child and parent process please refer to bug 1697745.
We have no automated test for this edge case, but we have diagnostic telemetry that will tell us if it helps.

Previously we were initializing IOUtils lazily when we received our first IO
request, but that could run into problems when
1. shutdown starts before submitting any IO requests, which would then fail to
add shutdown blockers for phases we have already passed; or
2. the first IO request comes from off-main-thread, which can not tell if the
shutdown blockers are added successfully.
Now we register an observer to initialize the event queue and add all startup
blockers in the `profile-after-change` phase. We can then be sure that IOUtils
will have its blockers added before `profile-before-change`.

These changes make nsDisplayCompositorHitTestInfo inherit directly from nsDisplayItem, which should shrink it slightly. This also simplifies the logic: hit testing information is now available at nsDisplayItem level as opposed to nsPaintedDisplayItem.

Which allows to run CSS.supports in chrome/user-agent context. We should
probably add a couple more tweaks for stuff like quirks or what not (the
`ParsingMode` enum), but that seem lower priority.
I only added the one-value version of CSS.supports because it should be enough
and supporting the two value version required a bit of awkward code due to when
we parse the CSS property name right now.

do not need to include nsLayoutUtils.h.

When we support `InputEvent.getTargetRanges()`, editor needs to create
`StaticRange` instances at starting to handle every edit operations/commands.
Therefore, we need a hack for saving allocation cost like `nsRange`.
This patch moves `nsRange::MaybeCacheToReuse()` and `nsRange::Shutdown()` to
`AbstractRange` to reduce copy&paste same code into `nsRange` and `StaticRange`.
However, `Create(nsINode*)` and `Release()` are duplicated unfortunately.

This patch makes `nsRange::Create()` reuse its instances automatically.
It's difficult to consider the limit of cache since `nsRange` instance is

create too many instances.

The idea of this patch is to try to not use oberver mechanism as possible. To
achieve that, it introduces deleteByOriginAttributes() to cleaners. Different
from other methods, it would only be executed if it's implemented from a
cleaner.
It doesn't remove oberver mechanism entirely since some cleaners are still using
that for other deleteByXXX() functions. So, it only applies removing stuff to
PushService, QuotaManagerService, ServiceWorkerManager, nsPermissionManager,
nsApplicationCacheService, and nsCookieService.
Since the original issue is related to QuotaManagerService, it adds xpcshell
test under the dom/quota/test/unit/ to ensure the behavior won't be changed
accidentally in the future.
