Only send the msg "Browser:UnselectedTabHover" when someone requests for the
msg, it can reduce non-necessary communication.

This msg is used to notify the status whether the cursor is hovering over the
unselected tab or not.
It's used for the media's feature, resuming the background video decoding.

The intermittent failure is caused by the innate drawback of the present test,
it doesn't be consistent with the behavior how we actually block the media.
Since we always block media implicit, it would be set in nsGlobalWindow's ctor.
We would never call blockMedia directly, so we can remove the function.

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.

when Simplify Page option is used on preview. Also, this patch keeps track of what browser
should be presented, based on whether the 'Simplify page' checkbox is checked.

We could register media control related event after the tab has active media.
But we still need to register "audioFocusChange" in the beginning, because it
affect every tab even the tab has no active media.

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.
