We can easily use Maybe<DataSourceSurface::ScopedMap> instead of
allocated the map on the heap. This does require some minor changes to
ScopedMap to properly support moves, but should be much more efficient.

Bug 1462355 - Part 7. Don't hit the SurfaceCache in FrameAnimator::GetCompositedFrame if possible. r=tnikkel

In FrameAnimator::GetCompositedFrame, we call SurfaceCache::Lookup even
when we use the composited frame directly and leave the lookup result
unused. The only value in performing the lookup could be to mark the
surface as used to avoid expiring it too soon, but
FrameAnimator::RequestRefresh should already be doing enough to keep it
alive, if the image isn't locked in the first place.

In FrameAnimator::RequestRefresh and AdvanceFrame, we currently create
several RawAccessFrameRef objects to the same frames, either to get
timeouts or perform the blending. With some tweaking, we can avoid
requesting the same frame more than once. This will avoid mutex locks on
the surface provider and the frame itself.

DrawableSurface only exposes DrawableFrameRef to its users. This is
sufficient for the drawing related code in general, but FrameAnimator
really needs RawAccessFrameRef to the underlying pixel data (which may
be paletted). While one can get a RawAccessFrameRef from a
DrawableFrameRef, it requires yet another lock of the imgFrame's mutex.
We can avoid this extra lock if we just allow the callers to get the
right data type in the first place.

RawAccessFrameRef ensures there is a valid data pointer to the pixel
data for the frame. It is a common pattern for users of
RawAccessFrameRef to follow up with a request for the data pointer
shortly after creation. We can avoid an extra lock by exposing this data
pointer from RawAccessFrameRef, and populating it via
imgFrame::LockImageData.

Bug 1462355 - Part 1c. Make individual image decoders to use updated Decoder/SurfacePipe methods. r=tnikkel

Bug 1462355 - Part 1b. Update Decoder and SurfacePipe plumbing to use updated imgFrame methods. r=tnikkel

We currently choose to set the animation parameters (blend method, blend
rect, disposal method, timeout) in imgFrame::Finish instead of
imgFrame::InitForDecoder. The decoders themselves already have access to
the necessary information at the time InitForDecoder is called, so there
is no reason to do this. Moving the configuration to initialization will
allow us to relax the mutex protection on these parameters.

This part simply reorganizes imgFrame, and subsequent parts will
introduce the necessary changes to SurfacePipe and decoders.

Just leaving enough for style and tests to compile. Otherwise it's really
confusing, specially when looking for webidl stuff, and can confuse contributors
too.

I prefer to keep the rest as is, since the rest I do sync (semi) manually.

PreprocessValue was calling BigIntObject::unbox directly, which doesn't
check for proxy objects. Add a BigInt branch to js::Unbox and use that
function instead.
