Dynamic changes are handled correctly because content property changes already
cause a reframe.
This implements the same bits as Blink / WebKit do (single content item which is
an image, otherwise gets ignored), except for the edge cases where you use this
on an image.
In order to handle the edge cases right, we completely isolate the
nsImageLoadingContent usage based on `mKind`.
Blink's and WebKit's behavior there makes no sense and it's erratic, what I
implemented is consistent (we apply to images as long as they don't generate a
box, and we don't look at alt text or broken icons), though I'll update to
whatever the WG decides in https://github.com/w3c/csswg-drafts/issues/2831 /
https://github.com/w3c/csswg-drafts/issues/2832.
I don't think it matters in terms of web compat in any case.

Currently, if an event is consumed in the main process, EventStateManager
does not send it to remote process. However, this is unexpected behavior
for some WidgetKeyboardEvent dispatchers. OS sometimes has consumed native
key events before sending applications. For example, Alt key on Windows
should activate menu bar of focused window but Alt key may be consumed before
focused window receives the event. In such case, we mark Alt keyboard event
as "consumed before dispatch", and chrome treat it like as its preventDefault()
is called in web content. (Note that for compatibility with other browsers,
the consumed state is not exposed to web content. So, Event.defaultPrevented
returns false in web content.)
Therefore, we need to treat "consumed" state and "cross process forwarding"
state separately. This patch makes calling WidgetEvent::PreventDefault()
always stops cross process forwarding for backward compatibility. Additionally,
for the special case mentioned above, this patch makes
WidgetEvent::PreventDefaultBeforeDispatch() take additional argument,
|aIfStopCrossProcessForwarding|. If this is CrossProcessForwarding::eStop,
the event won't be sent to remote process as same as calling PreventDefault().
Otherwise, CrossProcessForwarding::eHold, PreventDefaultBeforeDispatch() call
does not change "cross process forwarding" state. I.e., if the event's
StopCrossProcessForwarding() and PreventDefault() are not called until
EventStateManager::PostHandleEvent(), the event will be sent to remote process
as usual.

This changes the order of properties returned from gCS. The old order
doesn't make much sense, and other browsers don't agree on an identical
order either, so it should be trivial to change it. Also the spec isn't
super clear / useful in this case.
Several -moz-prefixed properties are excluded from the list due to their
being internal. I suspect they are never accessible anyway, so probably
nothing gets changed by this.

The reason why const_cast is used for nsLayoutUtils::GetNearestScrollableFrame
is that if we changed the function as well, it ends up scattering const_cast
in most call sites of the function. That's because GetNearestScrollableFrame
has a do_QueryFrame call for the given nsIFrame* and returns the queried frame,
so it will be like this;
const nsIScrollableFrame* GetNearestScrollableFrame(const nsIFrame*, ..)
Most call sites of this function are then calls do_QueryFrame for the returned
nsIScrollableFrame*.

GECKO_DISPLAY_REFLOW_RULES_FILE doesn't work when the sandbox prevents access
to the rules file.
Added mention to try `--setpref security.sandbox.content.level=2` to lower
sandbox defenses.
As a workaround, and because in most cases the rules are only "* 1" (log
everything), a new env-var GECKO_DISPLAY_REFLOW_PROCESSES=a/p/c enables all
reflow logging without needing a rules file.
It also adds the choice of which processes have logging enabled, based on the
giving letter:
- a: All processes,
- p: Parent process,
- c: Content processes.

The idea with this patch is that style code will first call
InlineStyleDeclarationWillChange before style declaration has changed, and SetInlineStyleDeclaration once it has changed.
In order to be able to report old attribute value, InlineStyleDeclarationWillChange reads the value and also calls AttributeWillChange (so that DOMMutationObserser can grab the old value). Later SetInlineStyleDeclaration passes the old value to
SetAttrAndNotify so that mutation events and attributeChanged callbacks are handled correctly.
Because of performance, declaration can't be cloned for reading the old value. And that is why the recently-added callback is used to detect when declaration is about to change (bug 1466963 and followup bug 1468665).
To keep the expected existing behavior, even if declaration isn't changed, but just a new declaration was created (since there wasn't any), we need to still run all these
willchange/set calls. That is when the code has 'if (created)' checks.
Since there are several declaration implementation and only nsDOMCSSAttributeDeclaration needs the about-to-change callback, GetPropertyChangeClosure is the one to initialize the callback closure, and the struct which is then passes as data to the closure.
Apparently we lost mutation event testing on style attribute when the pref was added, so test_style_attr_listener.html is modified to test both pref values.

Before this change, we don't acend up frame tree across different documents,
but it's possible that subframe document is scrolled out in the parent document,
if there are animations in such subframes, we should throttle the animations
too.

The EffectSet count does not exactly represent the count what we really need
for AnimationValueMap, but in most cases it matches. For example;
1) The element has two different keyframes animations
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { transform: rotate(360deg); }
}
In this case the number matches.
2) The element has two animations but both keyframes have the same CSS property
@keyframes anim1 {
to { opacity: 0; }
}
@keyframes anim2 {
to { opacity: 0.1; }
}
In this case the number doesn't match, moreover it results more memory than we
ever needed, but this case is presumably less common.
3) The element has an animation having keyframes for two different CSS
properties.
@keyframes anim {
from { opacity: 0; transform: rotate(360deg); }
}
In this kind of cases, the number doesn't match. But even so, this patch
reduces the opportunities that the AnimationValueMap tries to allocate a new
memory (i.e. less opportunities on expanding the map).
Note that when the hash map is expanded, we do allocate a new RawTable with the
new size then replace the old one with the new one [1], so I believe this
change will reduce the crash rate to some extent.
