This fixes PrintTargetWindows::BeginPrinting to detect when the
user cancels and have it return NS_ERROR_ABORT in that case.
The rest of the changes are simply making sure that the various
call points up the call stack don't print a warning message if
NS_ERROR_ABORT is returned up from
PrintTargetWindows::BeginPrinting.

This works around a rendering failure on Windows where the browser window opens
and remains white. Details of why this happens can be found in bug 1442748; this
workaround just forces a scene build if we get a GenerateFrame request after
having the root pipeline id set on the pending scene, but if it hasn't yet
been propagated to the current scene. This ensures the render isn't skipped
and prevents the C++-side frame throttler from preventing future composites.
This interface should be used for accessing any sampler-thread functions
on APZCTreeManager. Eventually the interface will handle thread
delegation so that if it is called from a thread that is not the sampler
thread it will redirect the calls appropriately. For now it just allows
to logically group the public APZCTreeManager methods that are to be run
on the sampler thread.

This static function has only two call sites. One (in GPUProcessManager)
is unused, so it can be removed. The other (in
InProcessCompositorSession) takes the returned APZCTreeManager and
exposes it as an IAPZCTreeManager. Instead of doing this, we can simply
expose it as an IAPZCTreeManager from CompositorBridgeParent itself, to
reduce the number of places that can potentially grab a handle to the
APZCTreeManager.

The sampler thread is similar to the controller thread in that it doesn't
correspond to a particular actual thread, but instead introduces an
abstraction that allows us to reason about code flow and data ownership
that is logically grouped on a single thread. For now the sampler thread
remains mapped to the compositor thread, but eventually we will allow
it to be render backend thread when webrender is enabled.

Calling GetIndirectShadowTree and holding on to the result - or holding
on to pointers from the LayerTreeState - is fine on the compositor
thread, but if we want to allow APZ to accept layer updates and scroll
offset sampling on some other thread, then we should avoid doing this.
This patch replaces calls to GetIndirectShadowTree with the
CallWithIndirectShadowTree function and ensures anything that outlives
the function is held on to with a RefPtr. Of course, this only takes
care of the more superficial concerns - we will also need to robustify
those classes' implementations to handle being called from multiple
threads; that will be tackled later.

This encapsulates the APZTestData better inside APZCTreeManager, which
we will want once we allow the hit-test tree update to happen on a
thread other than the compositor thread.

Instead of keeping track of all the layers ids that we've seen during
the tree walk, we can now just get notified when a layer subtree is
removed, and clear out the state for that layers id at that point.

These two structs store very similar state (including duplicating the mask layer common clip count), and the former uses an expensive hashtable for lookups.
This patch combines the two, and uses a vector of entries instead of the hashtable so we can do the cleanup pass.

image.animated.decode-on-demand.threshold-kb is the maximum size in kB
that the aggregate frames of an animation can use before it starts to
discard already displayed frames, and redecode them as necessary. The
lower it is set to, the less overall memory we will consume at the
expense of execution time for as long as the tab with the animation(s)
above the threshold are kept open.
image.animated.decode-on-demand.batch-size is the minimum number of
frames we want to have buffered ahead of an animation's currently
displayed frame. The decoding will request this number of frames at a
time to maximize use of memory caching. Note that this is related to the
above preference as well; increasing the batch size will in effect raise
what the minimum threshold. This simplifies the logic in patches later
in the series.
Now that what we use to decide whether a document is styled by Servo are only
prefs and the doc principal, we don't need to inherit the style backend type,
since unless the pref has changed, the result will be the same.

In some cases we can end up with a PaintedLayerComposite still present
in the layer tree but with its mBuffer cleaned up. Whether this should
be occurring or not is still under discussion, but nevertheless a
PaintedLayerComposite without its mBuffer should not be considered
opaque, and treating it as opaque results in a black flash on OSX when
following links from the activity stream.

As for now, the scrollable direction with a mouse wheel for a single-line text
control is hard-coded; that is, only horizontal wheel scrolls are able to take
effect while vertical ones aren't. However, this isn't the desired case for
vertical writing mode, where the opposite case definitely suits better.
This commit refines the hard-coded scrollable direction for a single-line text
control to be writing-mode-adaptive.
