This flag indicates that document can flush parent-document only or need to do
the normal flushing.

Right now every document in a docshell makes a copy of the list. In practice,
this list is usually pretty short (limited by depth of iframe nesting), so this
is probably not a problem. We could add a bit of complexity and have a
refcounted struct that contains the list... I wish we had something as simple
as Rust's Arc that we could use here.

Per mixed-content-blocked spec, [1], <img srcset> and <picture> should
be blocked. However we still fetch <img srcset> and <picture> in image
preload, because they are fetched with contentPolicyType
TYPE_INTERNAL_IMAGE_PRELOAD and won't be rejected by nsMixedContentBlocker.cpp.
So I updated the image preloading code, and use the type TYPE_IMAGESET
if the image request is for <picture> or <img srcset>, otherwise for
normal image load we still use TYPE_INTERNAL_IMAGE_PRELOAD.

4. Return allowed if one or more of the following conditions are met:
request’s type is "image", and initiator is not "imageset".
5. Return blocked.
We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

nsTextFrame stores text as single byte character array if all characters are
less than U+0100. Although, this saves footprint, but retrieving and modifying
text needs converting cost. Therefore, if it's created for a text node in
<input> or <textarea>, it should store text as char16_t array.

Our current machinery for enabling stylo requires a docshell - if there isn't
one, we default to the Gecko style system.
When getComputedStyle operates on an element without a presshell, it uses the
caller's presshell instead. If the element has previously been styled with
one style system (but no longer has a presshell), and the caller uses a
different style backend, using the caller's style system can cause crashes when
we pull bits of cached data off the DOM (like cached style attributes).
So we want to throw when window.getComputedStyle(element) is called for a
(window, element) pair with different style backends (which is what the next
patch in this bug does).
However, that causes a few failures where stylo-backed documents try to do
getComputedStyle on an XHR document (which, without a docshell, will use the
gecko style system).
So this patch does some work to propagate the creator's style backend into
various docshell-less documents. This should allow both chrome (which uses gecko)
and content (which uses stylo) to use getComputedStyle on the response document
for XHRs they create.
Note that the second patch in this bug will make
chromeWin.getComputedStyle(contentObj) throw. If we discover code that does
that, we can just make it invoke the content's getComputedStyle method over Xrays.

The spec puts it on the Document interface, not HTMLDocument, so it
should apply to XML documents as well. In general we want APIs to be
available for all types of documents unless there's a specific reason
not to.

I've been having problems with interdiffs on mozreview lately, so for
ease of review, this patch is being submitted as a seperate patch for
review. Once it is r+'d, it will be folded into the first patch in
this set before landing.

This commit changes async keyboard scrolling to be enabled only if the content to
scroll is from a selection. This works around the problem of detecting whether
an arbitrary element has key listeners that should prevent async key scrolling,
because when they have the focus we will have disabled async key scrolling.

The <content> in an XBL document could be injected into documents with
different style backend types. Therefore, we need to set the XBL document's
style backend to the same as the bound document's so that the style
attribute of the content can be processed by the correct backend. <marquee>
elements in xbl-marquee.xml is one such example.

In our current setup, in which links with an href attribute always match either
:link or :visited, no matter whether that attribute's value is a valid URI,
changes to the attribute always put the element into either the "match nothing"
state or the "match :link" state, via calls to Link::ResetLinkState.
The only thing FlushPendingLinkUpdates is needed for is (lazily, in case it
turns out to not be needed because the element got removed from the DOM anyway)
registering a history observer to switch the link state to :visited as needed.
This means that selector matching consumers that would never expose :visited
state to start with don't need to worry about calling FlushPendingLinkUpdates.
Other browsers do not support any of these (IIRC), telemetry reports
essentially zero usage, and supporting them is contrary to the DOM spec.
Notes on specific events:
CommandEvent and SimpleGestureEvent: These are not supposed to be
web-exposed APIs, so I hid the interfaces from web content too
(necessary to avoid test_all_synthetic_events.html failures).
DataContainerEvent: This was a non-standard substitute for CustomEvent
that seemed to have only one user, so I removed it entirely and switched
the user (MozillaFileLogger.js) to CustomEvent.
ScrollAreaEvent: This is entirely non-standard, but we apparently expose
it deliberately to web content, so I didn't see any reason to remove it
from createEvent.
SimpleGestureEvent and XULCommandEvent: Can still be created from
createEvent(), but not by content.
TimeEvent: This is still in because it has no constructor, so there's no
other way to create it. Ideally we'd update the SMIL spec to add a
constructor. I did remove TimeEvents.

SelectorCache::NotifyExpired() will be invoked by nsExpirationTracker::TimerCallback() from an unlabel runnable.
We adopt the change in nsExpirationTracker to provide a DocGroup EventTarget for the invocation of this callback.

The next patch moves nsCSSFontFaceRule into a separate header, which
somehow affects lots of header dependencies. I'm not completely sure
why this happens, though.

We should let window decide whether resume the media component, not document.
Because we might have media component which is not in DOM tree, but we still
want to play it.
Window should be resumed when all following conditions are true,
(1) the tab is in the foreground
(2) there is any alive media component (MediaElement/WebAudio/PlugIn...)
(3) the window is blocked (nsISuspendedTypes::SUSPENDED_BLOCK)
