AHardwareBuffer is supported since Android O(APIVersion 26). Implementation of AndroidHardwareBufferTextureData referred AndroidNativeWindowTextureData. Implementation of AndroidHardwareBufferTextureHost referred obsoleted GrallocTextureHost.
android fence is not supported yet.

Allows to remove the dance around the compositor thread just to perform the assertion.
The use of an in-line lambda avoid all ambiguity on which thread this is called.

There's a small race that can happen when the remote decoder gets shutdown during xpcom shutdown; that would cause GetCurrentSerialEventTarget to return null. Leading to an assertion failure in ActorLifecycleProxy thread-safety check when PRemoteDecoderManagerParent gets destroyed.
So we use a background taskqueue instead and cleanup a bit the threading code in there allowed thanks to the TaskQueue ability to not require an explicit shutdown.

This also adds telemetry probes to track:
* number of times remote canvas 2D is activated
* number of times remote canvas 2D is deactivated due to device creation failure
* number of times remote canvas 2D is deactivated due to a stream read error.

We are here, always actually dealing with the compositor thread, with the exception of VRDisplayPresentation which is passing the main thread.

Now CompositorAnimationStorage::GetAnimatedValue() and SetAnimatedValue()s
are called on the sampler thread in case of WebRender, are called on the
compositor thread in case of non WebRender, so we drop assertions of
IsInCompositorThread check there. A mLock.AssertCurrentThreadOwns call in
each function should make sure the function gets called on the
sampler/compositor thread with acquiring the lock.
One caveat in this change is that in case we try to get an animation value via
nsIDOMWindowUtils.getOMTAStyle(), we do sample animations on the _compositor_
thread and we never call UpdateDynamicProperties, which means if it gets called
in testing refresh driver mode, visual results will differ from what the value
returned by the getOMTAStyle should look like. But it should be fine because we
disallow using any chrome priviledge APIs in reftests and also we will never use
the testing refresh driver mode in the reftest harness. Also in mochitests the
visual results' differences might make people confusing if the person can notice
it, but in principal getOMTAStyle() is designed to get computed animating values
so that it doesn't matter what the visual result is.

When a transform depends on the layout size of an element, one can see
visual distortions caused by the difference between the unsnapped size
used in the transform, and the snapped size calculated during scene
building. Ideally we could compute the transform after we snap, rather
than before. This patch adds support for a computed reference frame
which takes parameters to calculate the ideal transform dynamically.
In a future patch, we should make videos take advantage of this same
mechanism to avoid similar problems. This requires support for mirroring
and rotations.

We can perform the same function as RecyclingSourceSurface by checking
the ref count of the underlying surface directly. We need to ensure
WebRender is explicitly aware that it is a recycled surface, but that is
easily achieved by changing the type of the surface. This avoids
unnecessary heap allocations, particularly in the case where many
elements on the same page refer to the same animation (and thus
duplicating RecyclingSourceSurface objects).

This patch implements:
- Global surface UID for better tracking/debugging. The UID is passes acros all processes so we can track
surface usage.
- WaylandAllocateShmMemory() function which uses shm_open() instead of files at tmp for Shm memory creation.
- DMABufRefcount() class based on eventfd() which is used as a global surface reference count.
