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.

It's easy to mess up the scoping so that (a) the label is pushed and then
immediately popped, and/or (b) the string doesn't live long enough. It's also
easy to do a utf16-to-utf8 conversion unnecessarily when the profiler is
inactive. This patch splits that macro into three new ones that are harder to
mess up.
- AUTO_PROFILER_LABEL_DYNAMIC_CSTR: same as current.
- AUTO_PROFILER_LABEL_DYNAMIC_NSCSTRING: for nsCStrings.
- AUTO_PROFILER_LABEL_DYNAMIC_LOSSY_NSSTRING: for nsStrings.
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.

Push pointer event pref before testing test_assign_event_data.html and remove redundant assertions since the pushed pref will be restore after testing.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

By returning true from WebRenderLayerManager::EndEmptyTransaction, we
avoid doing a full paint in cases where the caller decides an empty
transaction would be sufficient. WebRenderLayerManager already rejects
attempts to set some forms of empty-transaction data (specifically
transform and scroll offset updates). This means that we will never get
a call to EndEmptyTransaction where the caller is expecting a transform
or scroll offset update to be sent over to the compositor. So if we have an
implementation of EndEmptyTransaction that ignores that data, it will not
break expectations.
There is still one piece of information that WebRenderLayerManager
doesn't reject in this manner, the APZ focus state. That is, if the
layout code sets a pending APZ focus state on the WRLM, followed by a
all to EndEmptyTransaction, it expects the focus state to get propagated
to the compositor. This patch makes sure that it does happen by using
the new API added in the previous patch.

Revise the pointer event implementation, includes
- Revise the implementation to fetch preference values.
- Separate the logic to get the pointer capturing frame to PointerEventHandler.

This isn't a super essential feature, and is just a change to try to bring us in
line with chromium and the spec. As this has apparent web compat issues, and
DataTransfer is a hard to test area, this patch moves the changes behind a pref,
which we can come back to turning on after we ship 57.
This ensures that, if the touch event is over a scrollbar thumb and
makes it into nsSliderFrame::StartAPZDrag(), nsSliderFrame knows
that the event went through APZ and that therefore APZ will handle
the drag.

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.
