This patch re-enables the new behavior of bug 1479964, to set keyCode or
charCode of keypress event whose value is zero to the other's non-zero value.
However, some web apps are still broken with the new behavior. Therefore,
this patch adds a blacklist to keep using our legacy behavior in some specific
web apps.
Note that Google Docs, Gmail and Remember The Milk are reported as broken.
However, I don't see any broken shortcut with Gmail. Therefore, this patch
adds only Google Docs and Remeber The Milk into the blacklist.

We can wait for the button fix if you want, but it was easy enough to fix, I
think.
I think we could merge NativeAnonymousContentRemoved with the walk that
NotifyFrameRemoved does, since the content should still be in the tree when that
happens. If you want, I can do that as a followup.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

PresShell::PageMove() climbs up to parent document when there is no scrollable
parent in current document. However, if aExtend is true, it should expand
Selection in the document itself. Therefore, it needs different rules to
look for container of expanding Selection from scrollable element to scroll.
Additionally, old rules (i.e., before the fix of bug 1369072 which caused
this regression) were also buggy. It used parent scrollable element or
root scrollable element simply. Therefore, if found scrollable element is
ancestor of selection limiter, it didn't work as expected.
This patch creates nsFrameSelection::GetFrameToPageSelect() to retrieve
per-page selection container element with the following rules:
- look for a scrollable element in selection limiter.
- if there is no scrollable element, use selection limiter.
- if there is no selection limiter, use the root frame.
So, nsFrameSelection::CommonPageMove() should take nsIFrame rather than
nsIScrollableFrame since container of per-page selection may be used in
non-scrollable contenteditable element. If it's called with non-scrollable
frame, it needs to compute the expanding range with the frame size.

nsRefreshDriver::ObserverArray is a nsTObserverArray which is
infallible, so no need to check the return value from AppendElement
(which a later patch in this series will remove).
If class A is derived from class B, then an instance of class A can be
converted to B via a static cast, so a slower QI is not needed.

It can flush the parent document from MediaQueryList::RecomputeMatches, which
can destroy our pres context.
I think that flush is wrong btw, it should probably either flush layout so the
viewport size is correct, or just not flush (we should make MediaList::Matches
take a document now that we don't need a pres context to match media queries,
but that requires a bit more refactoring).

AccessibleCaretEventHub is an nsISelectionListener of Selection whose type is
"normal". This is added only when nsFrameSelection::Init() is called and
accessible caret is enabled. Additionally, nsFrameSelection::Init() is
always called immediately after creating nsFrameSelection.
Therefore, when AccessibleCaretEventHub is installed to Selection, this is
always second selection listener and won't be installed multiple times. So,
Selection can store pointer of AccessibleCaretEventHub directly only when
it's enabled and the Selection needs to notify it of selection change.
This patch makes Selection stores AccessibleCaretEventHub with RefPtr, then,
makes Selection::NotifySelectionListeners() call its OnSelectionChange()
immediately after AutoCopyListener.
Unfortunately, this patch includes making of MOZ_CAN_RUN_SCRIPT_BOUNDARY and
MOZ_CAN_RUN_SCRIPT a lot since some methods of AccessibleCaretEventHub are
marked as MOZ_CAN_RUN_SCRIPT and including AccessibleCaretEventHub.h into
Selection.h causes compile the compile errors.

When CSS rules change, we usually do this implicitly from FlushUserFontSet & co.
However there's a code path that dirties the stylist but not the CSS rules, and
that's when the compat mode changes and we're an SVG document.
I don't think that can get hit (easily, at least?), but it's pretty easy to do
so and I think this is cleaner too.
This fixes that case so the stylist can't assert in that case either, and so
that we still rebuild the cascade data so that the hash maps use the right keys
for a given quirks-mode.

This change also renames several related functions, as well as fields,
and the header is moved into EXPORTS.mozilla given it is defined under
mozilla namespace.

Summary:
This fixes a couple fuzz bugs and prevents special-casing <svg:use> even more in
bug 1431255.
Unfortunately not as many hacks went away as I'd have hoped, since we still need
to match document rules, see the linked SVGWG issues.
But blocks_ancestor_combinators goes away, which is nice since it's on a very
hot path.
Test Plan: WPT for style invalidation, covered by existing tests otherwise.

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.
