Both libjpeg and windows.h typedef `boolean` to different types (`int` and
`unsiched char` respectively) and nsJPEGEncoder's public definition includes a
function that returns a `boolean`. Exposing this header results in type
conflicts.
We now isolate the internals of nsJPEGEncoder into a friend class whose
internals are hidden from the publica, allowing the header to exported.

MozPromise most common use is to have an single or exclusive listener. By making the MozPromise generated by IPDL exclusive we can also use move semantics.
While at it, we also use move semantics for the ResponseRejectReason and via the callback's reject method so that the lambda used with the MozPromise::Then can be identical to the one used by the IPDL callback.
As it currently is, it provides no advantage over a copy as it's just an enum; however, this will facilitate future changes where it may not be.

When an animation is reset, we can actually avoid the reallocations by
keeping the frames in the mRecycle and mDiscard queues. There is no real
need to do this. We just need to make sure the recycle rect calculation
is done appropriately, particularly when we haven't reached the end yet
and thus don't know the first frame refresh area yet.

The size was originally incremented in AnimationFrameBuffer::Insert
however if an animation was reset before we finished decoding, it would
count some frames twice in the counter. Now we increment it inside
InsertInternal, where AnimationFrameDiscardingQueue can make a more
informed decision on whether the frame is a duplicate or not.
Additionally we now fail explicitly when we insert more frames on
subsequent decodes than the original decoders. This will help avoid
getting out of sync with FrameAnimator.

If an animated frame buffer was reset just before the necessary frame to
cross the discard threshold, followed by said frame being inserted by
the decoder, it would insert a null pointer into the display queue for
the first frame. This is because it assumed that we have always advanced
past the first frame -- which was true, but the reset placed us back at
the beginning.
This would initially manifest to the user as the animation stopping,
since it could not advance past the first frame. Once a memory report
was requested, it would crash because we assume every frame in the
display queue is valid.
This patch removes the assumption about what frame we have advanced to.

combination of strategies including disabling of formatting, some manual

When bug 1508393 landed, it not only enabled producing of full frames
on the decoder threads, it also enabled recycling of old animated image
frame buffers it would have otherwise discarded. It reuses the contents
of the buffer where possible given we know what pixels changed between
the old frame and the frame we want to produce. However where this
calculation was done was incorrect. We originally calculated it when we
advanced the frame, but at that point there is no guarantee that we have
all of the necessary information; we may have fallen behind on decoding.
As such, we move the calculation to where we actually perform the
recycling. At this point we are guaranteed to have all the necessary
frames between the recycling and display queues.

WebRender takes longer than OMTP to release its hold on the current
frame. This is because it is in a separate process and holds onto the
surface in between rendering frames, rather than getting a reference for
each repaint. This patch makes us less aggressive about taking the most
recent surface placed in the recycling queue out to avoid blocking on
waiting for the surface to be released.

Also, fix a minor bug where when we discard an animated image that is a
full frame animated image, we need to reset
AnimationState::mCompositedFrameInvalid to false, just like we do for
animated images blended by FrameAnimator. This is because it is used as
part of our state checking in FrameAnimator::GetCompositedFrame before
we are willing to yield frame data.

Redecode errors break the state machine of FrameAnimator, since the
decoder and the animation state are now out of sync. Going forward this
tight coupling should be eliminated, as the decoder will produce full
frames and the animator can just take the current frame without worrying
about its relative position. For the moment, we should just not reset an
animation if it hit a redecode error (likely due to OOM) just like how
we already stop advancing the animation before the reset.

There were two unrelated buffering problems in nsWebPDecoder. The first
was with the decoder contract. We are expected to loop until the
iterator is unable to provide more data, and wait for the SourceBuffer
to reschedule us, where as nsWebPDecoder::DoDecode only did one pass.
Thus when something yielded wanting more data, we would just wait
forever.
The second was the integration with the libwebp API. We are expected to
retry when we receive SUSPENDED from the decoder, as it decided to yield
pixels instead of continuing to decode as many as possible.
The tests did not cover the first problem because multi chunk decoder
tests do not use SourceBuffer scheduling. This is an oversight. They now
will write a chunk of data, let the SourceBuffer reschedule the decoder,
and repeat until all of the data has been written.
The tests did not cover the second problem because all of the reference
WebP images are too small. This patch adds a new test with a large WebP
image (converted from a Mozilla all hands photo of lanyards). This
should actually trigger the SUSPEND behaviour of libwebp.

For decoders which produce unpaletted partial frames (APNG, WebP), the
surface format should always be BGRA. These frames while partial, are
the same size as the output size of the animated image. When
FrameAnimator performs the blend with the compositing frame, it expects
all pixels we don't care about to be set to fully transparent. If it is
BGRX, they will be set to solid white instead.

First we did not handle the SourceBufferIterator::WAITING state which
can happen when we get woken up but there is no data to read from the
SourceBufferIterator. StreamingLexer handled this properly by yielding
with NEED_MORE_DATA, and properly scheduling the decoder to resume. This
patch does the same in the WebP decoder.
Second nsWebPDecoder::GetType was not implemented. This meant it would
return DecoderType::UNKNOWN, and would fail to recreate the decoder if
we are discarding frames and need to restart from the beginning. In
addition to implementing that method, this patch also corrects an assert
in DecoderFactory::CloneAnimationDecoder which failed to check for WebP
as a supported animated decoder.
This patch also modestly improves the logging output and library method
checks.

We should only assert that the caller is requesting the first frame or
we have advanced to or beyond the expected initial frame, when we
successfully return a frame. This is because FrameAnimator will request
on refresh ticks for the current frame again, until it observes it. If
decoding is still behind, then we likely still have frames to
auto-advance, and we will trip the assert.
