Image decode tasks dispatched to TaskController pool threads can still
run after xpcom-shutdown-threads, because TaskController is only shut
down very late in the process teardown sequence. This causes
NotifyDecodeComplete and DropImageReference to attempt dispatching to the
main thread after it has stopped accepting events, triggering a
!mRawPtr assertion in already_AddRefed's destructor.
Check DecodePool::IsShuttingDown() in DecodingTask::Run() before running
the task, matching what AnimationSurfaceProvider already does internally.
Also update the comment in SurfaceCache::ReleaseImageOnMainThread to
clarify that the shutdown path is unreachable in release builds and the
(void)aImage cast is intentional to preserve the DEBUG assertion.

This avoids potential issues where multiple OnDataAvailable callbacks or
similar could theoretically be called concurrently on different
StreamTransportService threads when targeting the STS - these cases will
now target a TaskQueue on the STS instead, structurally ensuring serial
execution.

COM is required for calls to SHGetFileInfo for moz-icon, but we only currently
require that for the file content process. We may want to use it in the future
for the privileged about content process, in which case we will have to forgo
win32k lockdown there unless moz-icon is remoted.

There are no code changes, only #include changes.
It was a fairly mechanical process: Search for all "AUTO_PROFILER_LABEL", and in each file, if only labels are used, convert "GeckoProfiler.h" into "ProfilerLabels.h" (or just add that last one where needed).
In some files, there were also some marker calls but no other profiler-related calls, in these cases "GeckoProfiler.h" was replaced with both "ProfilerLabels.h" and "ProfilerMarkers.h", which still helps in reducing the use of the all-encompassing "GeckoProfiler.h".

Also, add `clang-format off` directives to files which are ignored by

We should not attempt to shut down threads which we did not explicitly
remove from the image decode thread pool, when we want to shut down an
idle thread or otherwise. This behaviour would put us at risk of
shutting down a thread twice, which may trip assertions and/or cause
other issues. Now we assuming that any thread that is already removed
from the pool array has already been gracefully shutdown.

The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.
find . -name "*.idl" | grep -v web-platform | grep -v third_party | while read path; do
interfaces=$(grep "^\(class\|interface\).*:.*" "$path" | cut -d' ' -f2)

regexp="\("

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Currently it's completely unclear at use sites that the getters for `once`
static prefs return the pref value from startup, rather than the current pref
value. (Bugs have been caused by this.) This commit improves things by changing
the getter name to make it clear that the pref value obtained is from startup.
This required changing things within libpref so it distinguishes between the
"base id" (`foo_bar`) and the "full id" (`foo_bar` or
`foo_bar_DoNotUseDirectly` or `foo_bar_AtStartup` or
`foo_bar_AtStartup_DoNotUseDirectly`; the name used depends on the `mirror` and
`do_not_use_directly` values in the YAML definition.) The "full id" is used in
most places, while the "base id" is used for the `GetPrefName_*` and
`GetPrefDefault_*` functions.
(This is a nice demonstration of the benefits of the YAML file, BTW. Making
this change with the old code would have involved adding an entry to every
single pref in StaticPrefList.h.)
The patch also rejigs the comment at the top of StaticPrefList.yaml, to clarify
some things.

Windows doesn't like more than one thread (at the same time?) calling SHGetFileInfoW. So we use the same thread to avoid this.
We also need to call CoInitialize on the thread we do this.

This mutex only protects the iothread, not the rest of the decodepool. There is a different monitor for that in DecodePoolImpl.

If class A is derived from class B, then an instance of class A can be
converted to B via a static cast, so a slower QI is not needed.

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..

When we shutdown the decode pool threads, it does not do a simple join
with the main thread. It will actually process the main thread event
loop, which can cause a bad series of events. The refresh tick could
still be running and advancing our animated images, causing the animated
decoders to continue running, which in turn prevents the decoder threads
from finishing shutting down, and the main thread from joining them.
Now we check on each frame whether or not the decoder should just stop
decoding more frames because the decode pool has started shutdown. If it
has, it will stop immediately.
