For testing purposes, it is useful to pass a null aWindow to the DOMMediaStream
constructor. This limits the amount of code that needs to be mocked to create
a mock media stream.

This patch is adapted from Tor bug 1517.
To offer some protection against timing attacks by JS content pages, in this
patch we round the various time-exposing APIs (such as Date and
Event.timeStamps) to the nearest 100 ms when the pref "privacy.resistFingerprinting" is on.

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.

Turns out runnables added through
MediaStreamGraph::DispatchToMainThreadAfterStreamStateUpdate on the same
iteration are all run in the same task. Creating them in the owning dom stream
in one task solves the timing issues and lets us add them
(and raise "addtrack") in individual tasks.

This adds support for HTMLMediaElement.mozCaptureStream() and
mozCaptureStreamUntilEnded() for a HTMLMediaElement playing a MediaStream.
This is up to spec, while capturing a HTMLMediaElement playing a file is not.
This incompatibility means we cannot mix sources for the returned MediaStream.
As such, a MediaStream returned while the HTMLMediaElement was playing a file
will only have content while the element is playing files. If the src changes
to a MediaStream, the stream will be empty.
It works the same way if a MediaStream was captured while the HTMLMediaElement
was playing another MediaStream.
This is due to TrackID management - MediaDecoder doesn't care, and creates new
tracks when you seek, so users are unable to keep track, while for MediaStream
we control everything from main thread and keep track of the TrackIDs used
previously.
This also adds a separate path from MediaElementAudioSourceNode so that we don't
forward video tracks when the returned MediaStream is only used internally for
WebAudio. We should in that case not require a DOMMediaStream but just forwarding
tracks to a TrackUnionStream should be enough, and will save us some cpu cycles.
This is however fine for now as it's simpler.

Sometimes a track is added to a stream synchronously (before the stream is
exposed to script), and sometimes asynchronously (see the mediacapture-main spec
on the "addtrack" event).
In the latter case we might still need to create the MediaStreamTrack object
synchronously for tracking purposes. CaptureStream of Media element playing a
MediaStream wants this.

This can reduce the include header dependency. MediaStreamVideoSink will inherit from DirectMediaStreamTrackListener. But we can't use forward declaration on MediaStreamListener because the usage of nsTArray<RefPtr<MediaStreamVideoSink>>.

After ending the MediaInputPort (to the playback stream) gets removed if locked
to the track specifically. Trying to remove the track at this point would try to
block it in the same MediaInputPort - but since it doesn't exist would trigger
an NS_ERROR instead.
