Some MSE streams will resend the same init segment. In these cases we can treat
the following data as belonging to the already existing stream. We do this by
reusing the same stream id. This stops us tearing down and restarting decoders
in these cases. This has the benefit of stopping us introducing gaps to audio
and/or video.

Re-creating a new demuxer is fine, provided that the SourceBufferResource exists. However, a resource is only created upon receiving an init segment.
The segment following a call to changeType() must be an init segment, will let the demuxer creation occurs there.

Previous commit added SetNextGetSampleIndexIfNeeded, let's re-use it for GetSample.
We continue to have an exception code as it caters for the most common code path, which is we retrieve one sample after the other.

The assumption that when calling GetNextRandomAccessPoint the next GetSample index would always be known was incorrect. It assumed that the call to GetNextRandomAccessPoint would always be preceded by a call to GetSample.
This is not always how the MediaSourceDemuxer called it.

Removing the 'using mozilla::Move;' lines.

When using a media element with a Media Source, the resource fetching algorithm is to be called in "local" mode:
https://www.w3.org/TR/media-source/#mediasource-attach
"Continue the resource fetch algorithm by running the remaining "Otherwise (mode is local)" steps, with these clarifications"
https://html.spec.whatwg.org/multipage/media.html#concept-media-load-resource
Under the local mode, the steps that would cause the element to fire suspend, stalled or progress can never occur.
We only prevent the stalled event to be fired, many websites rely on the progress event to be fired (such as when the init segment has been parsed). The HTML5 media spec will be amended to clearly indicate that progress is to be fired even with mediasource

Add .eslintrc.js to configure globals from mediasource.js and to add extra
rules to encourage use of let and const over var.
Linting changes:
- Prefer const and let to var. This provides tighter scoping and avoids
reassignment.
- Mozilla rules do not allow for shadowing of variables, so several tests have
had promise lists renamed to avoid this.
- Numerous minor fixes to formatting including using double quotes, spacing,
missing semicolons.
- Remove some unused variables.
- Arrays have spaces after opening braces and before closing braces, e.g.
[ "foo" ], this is to be consistent with our clang-format rules.
- Fix naming of resourcePathSeen in test_MediaSource_memory_reporting.html.

Non functional code.
SourceBuffer.changeType allows to reconfigure a sourceBuffer so that a new codec type or new container format can be fed later.
The new code is placed behind the media.mediasource.experimental.enabled pref.

This patch converts all the prefs in MediaPrefs to the new StaticPrefs system.
Note that the "media.wmf.skip-blacklist" pref was present in both MediaPrefs
and gfxPrefs. The copy in MediaPrefs was never used; this explains why this
patch does not add an entry for it to StaticPrefList.h.
Note also that the patch removes themedia.rust.mp4parser pref, because it's
unused.

PinForSeek() is called only when playback reaches the end. In other words,
it is not called for most cases of seeking. It should be OK not to call it at
all during seeking.

To prevent another heap allocation, we re-use the TaskQueue internal monitor.
As a TaskQueue is refcounted, and the MozPromise::Then() holds a reference to the taskqueue, it ensures that the monitor isn't immediately destroyed when Await() execution unwinds.
Instead it will live until either the lambda or Await() completes, whichever comes last.

Mostly-mechanical replacement of MOZ_LOG with DDMOZ_LOG, usually just removing
the class name and `this` pointer (as they are already implicitly recorded).
Some files needed a bit more work when logging was done from helper classes or

Mostly-mechanical additions:
- Log constructions&destructions, usually by just inheriting from
DecoderDoctorLifeLogger, otherwise with explicit log commands (for internal
classes for which DecoderDoctorTraits can't be specialized),
- Log links between most objects, e.g.: Media element -> decoder -> state
machine -> reader -> demuxer -> resource, etc.
And logging some important properties and events (JS events, duration change,
frames being decoded, etc.)
More will be added later on, from just converting MOZ_LOGs, and as needed.
