This patch tries to mark root callers of `nsINode::GetSelectionRootContent()`
which calls `nsINode::GetAnonymousRootElementOfTextEditor()` as far as possible
(and reasonable).
It's used by `ContentEventHandler` so that a lot of methods of
`EventStateManager`, `ContentEventHandler`, `IMEContentObserver` which are main
users of it are also marked as `MOZ_CAN_RUN_SCRIPT`. I think that this is
reasonable.
On the other hand, it might not be reasonable to mark `IMEStateManager` methods
as `MOZ_CAN_RUN_SCRIPT` for initializing `IMEContentObserver` because
`IMEStateManager` may be able to initialize `IMEContentObserver` asynchronously
and its root callers are in XUL layout code. Therefore, this patch uses
`MOZ_CAN_RUN_SCRIPT_BOUNDARY` for `IMEStateManager` at least for now.

The current formulation is inconsistent. If you call it with ScrollableDirection::Either it goes into nsLayoutUtils::GetNearestScrollableFrame which will return the first scroll frame with a non-hidden overflow. If you call it with any other ScrollableDirection it calls nsLayoutUtils::GetNearestScrollableFrameForDirection which returns the first scrollframe it finds that has non-hidden overflow AND has at least one dev pixel of scroll range.
So remove that function and call nsLayoutUtils::GetNearestScrollableFrameForDirection directly. This is a slight change of behaviour but it seems desirable for all callers.

Otherwise the only time it gets set is when the ZoomConstraintsClient specifically sets it in response to one of the things that can change it. But if the scroll frame gets reconstructed and one of those things don't happen it will be wrong.
This shows up with desktop zooming scrollbars because we check mZoomableByAPZ (or WantAsyncScroll()) before we use the apz scroll path in ScrollFrameHelper::ScrollBy().

Some method implementations are moved to the corresponding implementation files

There's no need to put this in nsLayoutUtils since it's so closely bound
to presShell anyway. So we move it from being a static nsLayoutUtils function
that takes a PresShell pointer, to being a method on the PresShell itself.
Two functional changes here:
1. Don't run the MaybeReflowForInflationScreenSizeChange code unless the
visual viewport actually changes
2. Run the MaybeReflowForInflationScreenSizeChange if the visual viewport
is reset.
These functional changes can be logically thought of as "group the font-
inflation reflow stuff together with the other visual-viewport-triggered
reflow stuff".

The current notification enumerates all windows and calls
SysColorChanged on them.
The current implementation of SysColorChanged is not quite sound, as it
really needs most if not all of what ThemeChanged does: SVGs can use
system colors, so we need to also invalidate the image cache for
example.
It's also not clear it deals correctly with propagating system color
changes to other documents.
In some cases we were even firing both theme changes and system color
changes at the same time. Unify this code paths.

If we called PaintFrame for drawWindow or something other than painting to the widget the visual scroll update won't make it to the compositor, so don't clear it.

Prior to this bug, it was necessary to handle non-e10s specially, because the
resolution was being unapplied at the process boundary, and in non-e10s there
was no process boundary.
The remaining patches in this bug move the resolution unapplication away from
the process boundary in all cases, making special handling for non-e10s

Users have much better, easier alternatives, like
DOMWindowUtils.{loadSheetUsingURIString,removeSheet}, which we use to
replace the only caller that exists in mozilla-central (the editor
element, which loads EditorOverride.css).
This allows to clean up the style system and editor. There are other
callers in comm-central, but it seems they can switch to DOMWindowUtils
trivially, as the DOMWindowUtils APIs also use the system principal and
thus they can load any URL.
I'll make sure to give them some time with the migration and/or help
out of course.

This rejiggers a bit the way selection focus is handled so that focusing a
disabled form control with the mouse handles selection properly, and hides the
document selection and so on.
This matches the behavior of other browsers as far as I can tell.
Given now readonly and disabled editors behave the same, we can simplify a bit
the surrounding editor code.

The reason of intermittent failure of `test_bug656379-2.html` is, synthesized
`mousemove` event coming from the parent process causes `mouseout` and
`mouseleave` events of the last synthesized `mousemove` in the test. The
reason is, synthesized `mousemove` for tests makes `PresShell` in the content
process record the cursor location, but won't make it `PresShell` in the
parent process do it. Therefore, parent process may synthesize `mousemove`
event for the system cursor position which does not match with the synthesized
mouse location in the content process. Therefore, `:hover` state may be
updated unexpectedly.
This patch makes `WidgetEvent::mFlags` have a flag to indicate whether it
came from another process. Then, makes `PresShell::HandleEvent()` ignore
synthesized `mousemove` events coming from another process only when the
recorded mouse location was set by a mouse event synthesized for tests.

Long-pressing on a text in an unfocused iframe to select a word never
works. Currently, you need to single tap to focus the iframe first.
Each PresShell has an associated AccessibleCaretEventHub. This patch
fixes this bug by routing the event to the AccessibleCaretEventHub under
the event point, and handle it there. If the event is not handled, then
we handle it by the focused AccessibleCaretEventHub as before.
I've experimented with only routing the event to the
AccessibleCaretEventHub under the event point, without routing to the
fallback focused AccessibleCaretEventHub. However, caret dragging didn't
work in iframes. I didn't debug further.

It removes a script blocker. Therefore, although it depends on the caller
whether it causes running script or not. However, we should mark it as
`MOZ_CAN_RUN_SCRIPT` for safer code.
It's called only by the destructor of `nsAutoCauseReflowNotifier`. Therefore,
this patch also marks its constructor as `MOZ_CAN_RUN_SCRIPT` for making
each creator method marked as `MOZ_CAN_RUN_SCRIPT` or
`MOZ_CAN_RUN_SCRIPT_BOUNDARY`.
Most of the creators is mutation listener methods. However, `PresShell`
does nothing after destroying `nsAutoCauseReflowNotifier`. Therefore,
this patch does not change the callers in MutationObserver.cpp to use
`RefPtr<PresShell>` at calling them because changing it may cause performance
regression.
Perhaps, we should create another methods of `WillCauseReflow()` and
`DidCauseReflow()` to avoid unnecessary `MOZ_CAN_RUN_SCRIPT` marking.
However, I'm not sure whether most callers may run script or not because
of outside of my knowledge.

While it calls `RestyleManager::ContentStateChanged()`, it blocks script
with `nsAutoCauseReflowNotifier`. Therefore, it should be marked as
`MOZ_CAN_RUN_SCRIPT_BOUNDARY` at least (looks like the other override,
`DocAccessible::ContentStateChanged()` does not run script).
There is a concern about the lifetime of `RestyleManager`. It's destroyed
when `nsPresContext::DetachPresShell()` is called. It's called by
`PresShell::Destroy()` and destructor of `nsPresContext`. The latter is
safe since `PresShell` owns `mPresContext` and it's never cleared. However,
I'm not sure about the former. It might be better to create blocker of
synchronous handling of `PresShell::Destroy()`.
And also this does not make `Document::ContentStateChanged()` use
`RefPtr<PresShell>` at calling it because it might cause performance
regression, but it does not do anything after destroying
`nsAutoCauseReflowNotifier`.
Finally, for guaranteeing that the lifetime of `PresShell::mPresContext` is
longer than `PresShell`, this makes it to `RefPtr<nsPresContext> const`.
However, initializing it in constructor breaks other objects' initialization
process since they assume that `PresShell::GetPresContext()` won't return
valid pointer until the `nsPresContext` is attached. For solving this issue
safe, this patch keeps setting `mPresContext` in `Init()` with `const_cast`
hack.
