The reason we introduced the IsServiceStarted(), check bug1338466 comment5 for
more details.
The patch1 introduces more robust way to check the alive media component, so
we can remove IsServiceStarted().

In Fennec, the audio competiting is to stop the playing tab if there is new
incoming tab. We only implement the way to pause the tab, not including to resume
the tab, so we just need to run the audio competing related stuffs when the agent
is active.

In websites such as Facebook Live, timeout chains are used to drive the
playback of a video or something similar in JavaScript. Throttling the
minimum timeout values a tab playing a video from such websites in the
background could make the timeout based scheduling of video playback to
not work correctly, and cause audio buffer under-runs that are audible.
In order to address this, other major browsers don't throttle timeouts
in tabs that are playing audio. This brings us to parity to other
browsers (even though we already do this for websites that use Web Audio
since we've had similar bug reports using the Web Audio API.)
The current audio agent setup that drives the tab audio notification
icons is currently tracking whether a Window is playing audio. We use
this setup to decide whether to throttle timeouts when a window goes
into background.
Rename function MaybeNotifyMediaBlocked() to MaybeNotifyMediaBlockStart().

In present design, the tab would hide the unblocking icon when receives
the audio-playback event, but it means we can't hide the icon if the media isn't
audible.
For example, we won't show the unblocking icon for audio with audio track, but
we show the icon for audio with silent audio track which can only be detected
after starting decoding.
In this case, we can't receive the audio-playback after resuming that media.
Therefore, we should dispatch the different event to notify tab UI that the
tab has already been resumed.

In previous patch, we modify the behavior of nsDocument, now it would only resume
window when document has active media components.
However, it causes another issue. If the tab really goes to foreground, but
there is no active media component, the tab would still be blocked and it won't
be resumed anymore.
Therefore, we need to resume it by ourself if the tab is on the foreground but
doesn't be resumed yet.

For the first pinned tab, it would be set to visible first and then set to
invisible if there exists other tabs after restarting the whole browser.
If the tab is set to visible, we would activate the media component (set the
|mMediaSuspended| in outer window to none-suspend). In this case, the first
pinned tab would be set to visible briefly, but it doesn't mean the tab is in
the foreground, it's just how DOM manage the tab's visibility.
In that moment, none of the media component has been created yet. Therefore, we
would only activate the media component after the audio channel service exists.

We need to notify tabbrowser about media-blocking so that we can show the unblocking tab icon.

In general, the audio competing should only be for audible media and it helps user can focus on one media at the same time. However, we hope to treat all media as the same in the mobile device.
First reason is we have media control on fennec and we just want to control one media at once time. Second reason is to reduce the bandwidth, avoiding to play any non-audible media in background which user doesn't notice about.

This is built on top of the AudioChannel infrastructure. This patch does not
actually implement the capture, it just does the plumbing to be able to notify
all HTMLMediaElement/AudioContext for a document.

Right now this function is called after the XPCOM component manager is
shut down, so it can never remove any observers. It's better to do this
work in response to xpcom-shutdown while we still have a component
manager to be able to clean up after ourselves properly.
