This was observed in an intermittent failure of image/test/mochitest/test_discardAnimatedImage.html. What happened was:
1) Document::MaybePreLoadImage was called for the images in the test.
2) imgRequest::OnDataAvailable is called on at least one of the images. This creates the RasterImage, so any proxy for this imgRequest will now return the image via GetImage(). imgRequest::OnDataAvailable also queues the FinishPreparingForNewPartRunnable back to the main thread to call OnImageAvailable on the progress tracker on the main thread.
3) We get the actual LoadImage calls for the images of the document. We create new proxies for the existing imgRequests. imgRequestProxy::Init calls mBehaviour->SetOwner(aOwner), which sets mOwnerHasImage to true because the progress tracker has an mImage (the one we created above).
4) We get a call to LockImage, this gets forwarded to the RasterImage because mOwnerHasImage is true and we can access the image.
5) The FinishPreparingForNewPartRunnable finally runs on the main thread. The OnImageAvailable notification from the progress tracker ends up in imgRequestProxy::SetHasImage. imgRequestProxy::SetHasImage applies our local count mLockCount to the RasterImage, even though we've already forwarded one of those LockImage calls to the image. LockImage calls are now unbalanced and the image will always remain locked.
The fix is simple. Only apply the Lock/Unlock calls if the FinishPreparingForNewPartRunnable has hit the main thread (ie ignore an image we can access until this happens).

We have a better type to represent "a coord or nothing", and that's Maybe.
This code is shorter, and I think reads generally better / is less easy to
misuse.
I wrote this on top of bug 1547126 so there shouldn't be conflicts.

This patch moves remaining public `enum` of `nsIPresShell` to `mozilla`
namespace in `mozilla/PresShellForwards.h` and make them `enum class`es.
Additionally, some methods which use the moving `enum`s from `nsIPresShell`
to `PresShell`.

Changes:
- most tests are skipped using `moz.build` configuration file.
- `MultiWriterQueue` had to be skipped with `define` clauses in the test file due to build bustages when its `moz.build` file was used.

SVG performance with the fallback path with WebRender is very bad. This
patch avoids fallback by always producing a rasterized surface we store
in SurfaceCache, but also clamping the size consistently to a configured
maximum. This will cause us to upscale rasterized SVGs which is
undesirable visually but is a lower risk change that we can uplift to
beta than fixing the underlying performance issue.

This excludes dom/, otherwise the file size is too large for phabricator to handle.
This is an autogenerated commit to handle scripts loading mochitest harness files, in
the simple case where the script src is on the same line as the tag.
This was generated with https://bug1544322.bmoattachments.org/attachment.cgi?id=9058170

Disable gtests observed to fail on Android. Some of these are simple build
failures and failures due to file permissions or paths, while other failures
are more obscure.
Once Android gtests are running on mozilla-central, I will file follow-up
bugs inviting teams to investigate the failures and re-enable Android gtests
that are important to them.

The img decode API allows a web author to request that an image be
decoded at its intrinsic size and be notified when it has been
completed. This is useful to ensure an image is ready to display before
adding it to the DOM tree -- this will help reduce flickering.

nsIChannel.LOAD_CLASSIFY_URI is no longer required so we can remove it from
the codebase.
In the mean time, we add a new LOAD_BYPASS_URL_CLASSIFIER load flag for
channel creator to be able to force channel to bypass URL classifier check.
The use of the new LOAD_BYPASS_URL_CLASSIFIER flag will be addressed in
the other patches.

libpng uses the first IDAT chunk it encounters as a signal that it has read all header chunks and to send the info callback.
The testcase png has an IDAT chunk, then a z chunk (not a known chunk type), and then another IDAT chunk.
libpng tracks if we are in an "after idat" state, and throws a benign error if it encounters another IDAT chunk in "after idat" mode, but it just continues normally, processing the idat chunk as if it were the first and therefore sends the info callback again. This seems silly.
