This adds a WebRenderScrollData class (which contains a list of
WebRenderLayerScrollData objects, among other things), and adds it to
the DPEnd/DPSyncEnd messages sent across PWebRenderBridge. These classes are
skeletons for now (more stuff will be added to them in future patches).

Animations in content side could be removed easily by changing CSS, but the
CompositorAnimationStorage in parent side doesn't get updated. Therefore,
we store the layer's CompositorAnimationsId before layer is destroyed in
WebRenderLayerManager and then send out these discarded ids to parent on
the next layer transaction.

This introduces two new statistics to the overlay. The first is the ratio of
pixel shader invocations (as determined by the GPU) to the number of pixels we
determined need to be redrawn. The ideal ratio is 1.0, indicating that we
filled every pixel exactly once. Anything over 1.0 indicates overdraw.
We also add the ratio of shaded pixels to window size. This indicates how well
we computed the invalid region, and whether or not we overfilled that
region.
Note that the OpenGL and Basic compositors do not yet query the GPU for
this statistic, so they will estimate shader invocations by the area of
DrawQuad calls.
Finally, we remove the feature where layout can request the most
recent overdraw statistic. It was not implemented on all compositors, and the
only test that used it was disabled.
This call should be a no-op in the real world, and should be safe to
remove. The patch also adds an assert to ensure that the call is
effectively a no-op.

The goal of this patch is to remove the call to the sync IPC
GetCompositorOptions message from TabChild::InitRenderingState. In order
to this, we have InitRenderingState take the CompositorOptions as an
argument instead, and propagate that backwards through the call sites.
Eventually we can propagate it back to a set of already-sync IPC
messages in PCompositorBridge that are used during layers id
registration (NotifyChildCreated, NotifyChildRecreated, etc.). Therefore
this patch effectively piggybacks the CompositorOptions sync IPC onto
these pre-existing sync IPC messages.
The one exception is when we propagate it back to the AdoptChild call.
If this message were sync we could just use it like the others and have
it return a CompositorOptions. However, it is async, so instead we add
another call to GetCompositorOptions here temporarily. This will be
removed in the next patch.

Updating hit testing trees is very expensive for many layers, and often
layer properties that change don't necessitate hit testing tree updates.
While layer tree structure changes do, we can be smarter about
individual layer attributes.
This replaces the usage of |PR_LogPrint| with either |printf_stderr| or
|MOZ_LOG| where appropriate. |printf_stderr| is used where a logger is not
actually available or if log levels are not being used as expected.
This version of the Dynamic Toolbar moves the animation of the toolbar
from the Android UI thread to the compositor thread. All animation for
showing and hiding the toolbar are done with the compositor and a static
snapshot of the real toolbar.

WebRenderBridgeParent works independently, if root WebRenderBridgeParent is destroyed
without CompositorBridgeParent::StopAndClearResources() call,
non-root WebRenderBridgeParent are still active and could trigger ScheduleComposition().
The change prevents to trigger ScheduleComposition() in this case.
