Originally, DisplayPort suppression was a process-global static. This change makes it possible
to control DisplayPort suppression on a per-PresShell basis.

Now that BeginUpdate is useless for the UPDATE_STYLE case, we don't need the
update mechanism at all. Just ensure that ApplicableStylesChanged is called on
the pres shell via the relevant RuleChanged, etc. notifications.
There's a big hidden gotcha here. nsIDocument::BeginUpdate does put a script
blocker on the stack for these updates. However it's not needed, since no script
can run during these notifications (only the stylesheet events we post for
devtools, but those use AsyncEventDispatcher and PostDOMEvents, so they don't
try to run immediately).
nsIDocument::BeginUpdate also does XBL binding attached queue stuff, but we
can't change bindings during these notifications anyway, so it also doesn't
matter.

The dirty bit fiddling is nontrivial, but it's pretty much what we do for
invalidation and allows to keep this incrementally easily.
The only caller that we cared about for the GetFlattenedTreeParent check in
DestroyFramesForAndRestyle was the old ShadowRoot invalidation functions that
went away.

This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets

The nsCSSFrameConstructor bits are now handled in PresShell::Destroy along with
the other refresh driver observers.
I cleaned up the nsRefreshDriver methods because they were using infallible
append anyway, and that simplified the logic.

The font face set is owned by the document now, and the shell knows about
refresh driver ticks. There's no reason for it to live in the pres context.

Unfortunately this means that we need to export a couple more headers, but that
should be ok.
In particular, we have to export some headers that are #included by
nsCSSFrameConstructor.h, because nsCSSFrameConstructor.h itself will now be
included in more places outside of layout/, by .cpp files that don't necessarily
have the ability to indirectly #include its other headers, unless we export
them.

Instead move UndisplayedNode to its own file, which is what causes the include
hell due to requiring nsIContent / nsStyleContext.

Also, make them not rebuild the CascadeData synchronously, via the
FlushSkinSheets call, since that's broken. That fixes bug 1413119.
This is a little step in getting rid of XBL usage for Shadow DOM.

The event targets of touch events are not necessarily to be the same as their corresponding pointer events. So we don't have to cache the event target of pointer events when they are generated from touch.

This makes the pres shell be notified as the last observer unconditionally.
In practice this doesn't matter, and it may already be the case if an iframe
goes display: none and back. In practice, the only dependency that requires this
order is that the pres shell needs to be notified _after_ the content sink, so
we don't try to enter frame construction before beginning the shell update.
That may be worth looking into, but definitely not in the scope of this bug... :)

This makes it a bit more straight-forward to change the system font scale,
preserving the sync MediaFeatureChanged event.
This also avoids notifying media queries when the shell is not initialized.
In particular, the patch in bug 1404545 allows calling MediaFeatureValuesChanged
on a still-initializing pres-shell. This is nasty, and all this initialization
order is kind of a mess, but I'm not reworking it for now...
Also, this drops the invalidation of font-inflation when a doctype is added to
the document. GetViewportInfo() already relies on the doctype not changing, as
noted in a comment.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

I'm drive-by removing the comment about the frame tree state because I looked
into it, and the answer is: we properly restore it.
The gotcha is that we retain it too much, indeed, we retain it enough that it
can leak. See bug 1397239.

After the fix to bug 1294442 and bug 1324499, ResizeReflow began to be called
twice for each DOM update in webext popups, and we also artificially re-set the
scroll outside of ResizeReflow to counter the DidDoReflow callback in
nsHTMLScrollFrame setting scrolltop to zero due to the first reflow, which is
done with unconstrained height.
Because of the scrollport being reset we get spurious DOM scroll events.
Replacing the scrollport also interrupts smooth scrolling.
Move the double-reflow down one level into PresShell, doing it before
DidDoReflow is called. The scrollport is no longer reset (causing a spurious
scroll event), and we don't need to replace it (interrupting smooth scrolling).
Also partially fixes bug 1396034.

These functions are now dead code. And really, they were already dead code
even before this patch-stack -- they were only called in never-evaluated
(and now-deleted) #else clauses.
MozReview-Commit-ID: AeY6Z3ybmsv
This patch drops all MOZILLA_INTERNAL_API checks (and the bodies of any
associated "#else" clauses) from these files. The basic assumption here is
that MOZILLA_INTERNAL_API is #defined in all (supported) compilation units that
#include these files, so the checks are superfluous and the #else clauses are
dead code.
(If this assumption is mistaken and there is some .cpp file in our codebase
that #includes this header and yet does not have MOZILLA_INTERNAL_API, we will
find out via bustage on treeherder.)

When there is no selection and no focused content, aContent of
nsIPresShell::GetScrollableFrameToScrollForContent() is nullptr. Then, it'll
use root scrollable frame to scroll. However, the root scrollable frame may
be not scrollable. In such case, ancestor document's scrollable frame should
be scrolled instead.
