Currently we can only use the gfx.color_management.force_srgb pref to
force all images to sRGB, or just accept device space. It would be nice
to be able to test device space in our tests, as well as sRGB. This
patch adds a surface flag which allows us to selectively output sRGB.
This will also be useful for clipboard and re-encoding purposes, since
they want a neutral output. In an ideal world we would just output the
color profile and the pixel data in the original color space, but for
now this is a relatively simple approach that works on all platforms and
interops well with all applications.

To be able to remove SystemGroup, NS_ReleaseOnMainThreadSystemGroup
needs to have its dependency on SystemGroup removed. Since all
releases using SystemGroup would've released on the main thread anyway
we can safely replace NS_ReleaseOnMainThreadSystemGroup with
NS_ReleaseOnMainThread.
Depends on D64390

This patch converts the BMP decoder to use SurfacePipe instead of using
AllocateFrame and Downscaler directly. As a result, it now uses the
accelerated premultiplication path, honours the
SurfaceFlags::NO_PREMULTIPLY_ALPHA flag, and allows for a path forward
to support color management and clipboard better.

Given the crash resolved in part 1, it is possible for the blob
rasterizer in the compositor process to still be using surfaces after
the animation has advanced to the next frame. With recycling this can be
problematic as the recycled surface will be reused for a future frame.
In an ideal world, the blob recording would use the animation's image
key instead, but the rasterizer doesn't have easy access to the mapping
table. As such, for any frames used in a blob recording, we now
explicitly mark them as non-recyclable and we will be forced to allocate
a new frame instead.

The owner for the decoder may implement IDecoderFrameRecycler to allow
the decoder to request a recycled frame instead of allocating a new one.
If none are available, it will fallback to allocating a new frame.
Not only may the IDecoderFrameRecycler not have any frames available for
recycling, the recycled frame itself may still be in use by other
entities outside of imagelib. Additionally it may still be required by
BlendAnimationFilter to restore the previous frame's data. It may even
be the same frame as to restore. In the worst case, we will simply
choose to allocate an entirely new frame, just like before.
When we allocate a new frame, that means the old frame we tried to
recycle will be taken out of circulation and not reused again,
regardless of why it failed.

If we discard a frame during decoding, e.g. due to an error, then we
don't want to take that frame into account for the first frame refresh
area. We should also be handling partial frames here (the dirty rect
needs to encompass the rows that did not get written with actual pixel
data). The only place that can have the necessary information is at the
end rather than at the beginning.

Given an invalidation rect, called the recycle rect, which represents
the area which may have changed between the current frame and the frame
we are recycling, we can not only reuse the buffer itself to avoid an
allocation and free, we can also avoid copying pixel data from the
restore frame which is already set.

DecoderFlags::BLEND_ANIMATION will cause the decoder to inject the
BlendAnimationFilter from the previous patch into the SurfacePipe filter
chain. All frames produced by this decoder will be complete, and
should be equivalent to the result outputted by FrameAnimator.

It is possible for a decoder's iterator to be invalid in some error
conditions, all related to the ICO decoder seeking behaviour. Since we
assume that the iterator is always valid for the purposes of generating
the decoder's telemetry data, a malformed ICO image could cause a crash.
This patch removes the assumption that the iterator is valid, and
ensures we don't add the decoder's data to telemetry if it is invalid.
After decoding the first frame we allocate the second frame, but before it finishes we encounter an error, Decoder::PostError is called it aborts the second frame and decrements the frame count. But AnimationSurfaceProvider::CheckForFrameAtTerminalState just asks for the current frame ref from the decoder (which it never cleared) and inserts that.
The condition that we use from the decoder to decide to report a new frame is mFinishedNewFrame (via TakeCompleteFrameCount), however this doesn't directly correspond to mFrameCount. So we create a new bool on the Decoder to track when there is a frame that we can take.
This didn't cause any problems before but now we have tighter coupling between the list of frames the AnimationSurfaceProvider has and what FrameAnimator expects.
Another possible fix would be to clear the current frame ref in PostError, but the only place we clear the current frame is when we allocate the new frame and we have the mImageData pointer still around that decoders could theorhetically use to do final processing on the last partial frame.
Most cases where the pointer is stored into an already-declared variable can
trivially be changed to MakeNotNull<T*>, as the NotNull raw pointer will end
up in a smart pointer.
In RAII cases, the target type can be specified (e.g.:
`MakeNotNull<RefPtr<imgFrame>>)`), in which case the variable type may just be
`auto`, similar to the common use of MakeUnique.
Except when the target type is a base pointer, in which case it must be
specified in the declaration.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.
