It's a very general mechanism for replacing the implementation of
printf_stderr().
It's primarily used by the profiler, sparingly, and not in an important way.
Worse, it prevents us from using MOZ_LOG in the profiler, which is something I
want. Because if any code that locks gPSMutex also calls MOZ_LOG, that then
calls printf_stderr(), which calls profiler_log(), which locks gPSMutex, which
deadlocks.
The only other use of set_stderr_callback() is for the ultra-hacky,
for-local-use-only copy_stderr_to_file() function, which was added for B2G
debugging and is no longer necessary.
This patch removes set_stderr_callback() altogether.

If we disable APZ on an individual scrollable element by setting the "disable APZ"
flag on the ScrollMetadata, we should also disable paint-skipping for that element.
If we don't do this, we end up in a situation where the APZ code is not applying
the async transform but is sending repaint requests expecting the main thread to
do repaints. Meanwhile the main-thread thinks that it can send empty transactions
and have APZ update the async transform (a.k.a. paint-skipping). So visually
neither APZ nor main-thread have an effect and the element doesn't appear to
scroll except with the tile-aligned displayport shifts. Disabling paint-skipping
on the element fixes the issue.

Various pieces of browser chrome, such as the accessible carets or new
find-in-page highlighter, overlay the content with anonymous content elements.
These overlays are positioned with respect to the root document. This means that
if the overlay really pertains to a scrollable subframe (e.g. carets for a text
selection inside an iframe), then scrolling the subframe would result in the
anonymous contents being "mispositioned" from the user's point of view. The
browser chrome code that creates the overlay is responsible for moving it in
response to user scrolling, so that it appears correct. However, the only
mechanism the browser chrome code has to detect user scrolling are the main-thread
events, which are asynchronous with respect to APZ.
Therefore, in order to improve the user experience, we need to disable APZ in
cases where this happens. We specifically isolate the case where the root content
document has visible anonymous content elements, and disable APZ on scrollable
subframe elements inside that document. Note that APZ remains enabled on the
root scroller itself, because we expect the browser chrome code to use absolute-
positioning on their anonymous contents, so that even with APZ scrolling they
will stay where they are supposed to.

I think there are three advantages of this change:
1. removes some dependencies from layout / painting code to pre-computed
value stuff in the style system;
2. makes it easier to audit usage of specific fields in style structs
(which is probably a side effect of the first one);
3. potentially improves performance since it doesn't go through the
unnecessary general logic in ExtractComputedValue.
Also, combined with the part before, we get a unified list for visited-
dependent properties so that we can ensure the assertion here and the
style difference calc code are consistent.

If, within a single refresh driver tick, the scroll position is updated by JS
explicitly, and then subsequently also updated by a frame reconstruction, the
scroll origin from the former (nsGkAtoms::other) can get clobbered by the latter
(to nsGkAtoms::restore). The restore scroll origin is "weaker" in that it can
be ignored by the APZ code in some circumstances. This is undesirable because
it means the JS scroll update also gets ignored. This patch ensures that when
setting the scroll origin we don't do this clobbering of stronger origins with
weaker origins.

This patch introduces a new functions named HasEffectiveAnimationOfProperty.
This function checks that a given CSS property is overridden by !important
rules.
On the other hand, now KeyframeEffetReadOnly::HasAnimationOfProperty() does
just check that the effect has a given CSS property. This is used to create

transform animations even if the property is overridden by !important rules.

Note about no-stacking-context-(opacity|transform)-removing-animation-in-delay.html
Before this patch we don't create any stacking context for animations overridden
by !important rules, but after this patch we do create a stacking context for
such animations. As a result, in the test case we did paint a stacking context
in the first rAF callback and then in the second rAF callback we did clear the
painted stacking context. Unfortunately sometimes the second rAF callback was
called prior to clear the stacking context on the compositor because of
compositor delay. To avoid this situation, we have to wait for MozAfterPaint
instead of rAF callback.

KeyframeEffectReadOnly::HasAnimationOfProperty() calls GetAnimationOfProperty()
which checks mWinsInCascade flag and the mWinsInCascade flag is set to true
only if the effect is in-effect.
That means nsLayoutUtils::HasCurrentAnimationOfProperty() actually represents
that a given frame has at least one animation which is current and *in-effect*
(i.e. active).

Previously we weren't sending scroll position updates with origin nsGkAtoms::restore
over to the APZ at all, on the assumption that they should never clobber an APZ
scroll offset. However, there are scenarios where that is not true.
In particular, during a frame reconstruction, a layers update may be sent to the
compositor between the time a scrollframe has RestoreState() called on it, and
the time the scrollframe has ScrollToRestoredPosition() called on it. The layers
update that happens during this interval (correctly) sends a scroll position of
(0,0), and forces the APZ to scroll to that position. This is necessary to
prevent APZ from remaining at an invalid scroll offset while the frame is still
being rebuilt.
However, once ScrollToRestoredPosition() is called and the old scroll offset is
restored, that restored scroll position needs to get sent to the APZ in order to
have it properly restore to the original scroll position. In order to do this,
the main thread must flag the metrics with a scroll offset update. Since the user
may have scrolled concurrently in the compositor from the (0,0) position, we also
need to check for that case in the APZ code and avoid restoring the scroll
position. This is equivalent to the corresponding main-thread code in
ScrollToRestoredPosition().

This patch makes GetBounds(), GetScreenBounds() and GetClientBounds() more
obviously infallible, like existing functions such as GetNaturalBounds() and
GetClientSize(). This results in clearer behaviour in nsCocoaWindow.mm if
Objective C exceptions occur. Along the way, the patch removes some useless
failure checks for these functions.
The patch also removes the NS_IMETHOD from GetRestoredBounds and makes that
function MOZ_MUST_USE.
