We don't have an MP4 demuxer that can handle VP9 in non-fragmented MP4. Jay's
change to DecoderTraits in Bug 1339204 will make MediaSource.isTypeSupported()
report that it can play VP9 in MP4. But we don't want to report that we can
play VP9 in MP4 in HTMLMediaElement.canPlayType(), as usually canPlayType() is
used with the intention to check for whether fragmented MP4 can be played. So
we need to special case canPlayType() so that it reports that it can't play
VP9 in MP4.
The upcoming Rust demuxer will be able to support VP9 in MP4, so once we've
enabled that, we can confidently report in canPlayType that we support VP9 in
MP4.

If the blocked media is paused before resuming it, we should not resume it again
after the tab is visible. The way to achieve that is to unregister the agent so
AudioChannelService can't resume that media because we have disconnected their
relationship.

MediaContentType can only be created through MakeMediaContentType(), which
returns a Maybe<MediaContentType>.
If the return value is Nothing, parsing failed.
Otherwise the contained MediaContentType object is guaranteed to be valid;
E.g., GetMIMEType() will always return a non-empty string.
Note that this interface will change a lot in the following bugs&patches, so
please don't worry about the 'Get' in the never-failing GetMIMEType(), it will
be gone soon!

Because we add tracks to the output streams async, it's possible to switch the
mSrcStream of a media element and *then* get a notification of an added track,
when this track originated from the old mSrcStream.
If the new mSrcStream is an output stream of the media element, this would
again add a new track async, which on the next event loop spin would show up
on mSrcStream, and the loop continues.

With the attached test case I was failing an assert in a debug build because
NotifyMediaTrackEnabled exited early due to `mReadyState == HAVE_NOTHING` but
NotifyMediaTrackDisabled didn't. The latter would fail an assert.

According to current WhatWG HTML spec, the checking of media attribute in SourceElement is removed. Fix the Gecko code to reflect current spec.

W3C HTML5 spec isn't very actively maintained now. WhatWG HTML spec:
When a media element is removed from a Document, the user agent must run the following steps:
Below is the related statement in WhatWG HTML spec:
Await a stable state, allowing the task that removed the media element from the Document to continue. The synchronous section consists of all the remaining steps of this algorithm. (Steps in the synchronous section are marked with ⌛.)
⌛ If the media element is in a document, abort these steps.
⌛ Run the internal pause steps for the media element.

Dispatch |QueueLoadFromSourceTask| to main thread to make sure the task will be executed later than loadstart event. And when the src get errors, we need to end the synchronous section.

Buffered range is now calculated asynchronously. It may not be up to date by the time the MDSM has entered ended mode.
There's no point estimating readyState in ended mode anyway: we know what it is...
