Much like the component manager, many of the strings that we use for category
manager entries are statically allocated. There's no need to duplicate these
strings.
This patch changes the category manager APIs to take nsACStrings rather than
raw pointers, and to pass literal nsCStrings when we know we have a literal
string to begin with. When adding the category entry, it then skips making
copies of any strings with the LITERAL flag.

The patch introduces NS_GetURIWithNewRef and NS_GetURIWithNewRef which perform the same function.

The JPEG decoder will currently only post an invalidation when it has
processed all of the rows it is able to. If it is has all the data, that
means it must fully decode before invalidating. This causes very large
JPEGs to appear in large chunks which feels janky compared to slowly
appearing row by row with the refresh tick. With WebRender, it also
allows us to upload less data per frame update which can be another
source of jank.
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.
This patch adds three telemetry scalars to track how WebP is used. All
of these scalars are updated when we do the MIME type confirmation for
an imgRequest when the first data comes in. We know at this point we
decided to load the given content, so there should be minimal false
positives for data the browser loaded but never displayed.
The first two scalars are merely whether or not WebP was observed. One
is for probes, which are tiny WebP images suggested by the Google WebP
FAQ to probe for different aspects of WebP support (lossy, animated,
etc). We want to count this separately as actual WebP content that the
website wishes us to display. Probes will give a measure of how many
users visit websites that probe for WebP support, and content will give
a measure of how many websites don't care and just give us WebP images
regardless.
The third scalar is intended to give a relative measure of how many WebP
images we are being served relative to all other image types. We expect
the ratio to be small, but it would be good to confirm this from the
data.
This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

Crash reports indicate that SourceBuffer::mStatus is not set, and thus
SourceBuffer::AppendFromInputStream crashes due to dereferencing an
invalid Maybe<nsresult> object. Since SourceBuffer::Append cannot fail
without mStatus being set (or already set), it must mean that the input
stream failed to read all the data, and swallowed any internal errors.
While we used to assert in this situation, we also silently swallowed
the error historically. This patch will check mStatus, but if it is
unavailable, it will assert like before, and silently return otherwise.
This patch splits FontTableURI and BlobURL in 2 classes:
FontTableURIProtocolHandler and BlobURLProtocolHandler
both under mozilla::dom.
It also removes a memory reporter because that report is already covered by the
BlobURL one.

Same approach as the other bug, mostly replacing automatically by removing
'using mozilla::Forward;' and then:
s/mozilla::Forward/std::forward/
s/Forward</std::forward</
The only file that required manual fixup was TestTreeTraversal.cpp, which had
a class called TestNodeForward with template parameters :)

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

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.
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.
