This is a partial backout of Bug 1347791 part 3; a5fbb7e2d1d0.
We don't need to track in the front end code when a tab is foregrounded,
so we don't need to dispatch this message any more.

As well as the obvious #ifdef stuff, the patch removes
TCPSocket::SetAppIdAndBrowser(), which means
{TCPSocketParent,TCPServerSocketParent}::{GetAppId,GetInIsolatedMozBrowser}()
can also be removed.
When the block stauts of the window was changed, we would notify front-end side
to update the vaule, so that we can save it for session restore.

Since now we move the block/resume logic to front-end side, we can remove
the changing from bug1319771 and other related bugs which are used to ensure the
pinned tab should be blocked successfully after session restore.

When the agent is audible, we should check whether need to notify "blockStart"
immediately.

LazyLog can be used easily via adding the pref("logging.MODULE_NAME", DEBUG_LEVEL).
It's more convenient than PRLog.

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.

When user open new tab and then go to the pasted URL (which has autoplaying
media), the "play tab" icon would be displayed briefly, and then change to the
"mute tab" icon.
That is the media element starts before calling nsDocument::PageShow() which
would resume all blocked media in the tab. Before that moment, even the tab is
in the foreground, but we doesn't resume the media yet.
Therefore, we need to check the document's visibility by ourself, and only show
the "play tab" icon for the background blocked tab.
