We implement some helpful functions in MediaControlUtils which can be used to notify controller when media starts/stops playing or become audible/inaudible.
For now, we can temporarily notify these changes in AudioChannelService where we have already known when media has these kinds of status changing.

We don't want to enable audio competing by default, so hide this feature behind a static pref.

In order to support audio competing among different tabs, we implement a new class AudioFocusManager.
AudioFocusManager is used to assign the audio focus to different requester and decide which requester can own audio focus when audio competing happens.
When the audio competing happens, the last request would be a winner who can still own the audio focus, and all the other requesters would lose the audio focus.
Now MediaController is the onlt requester, it would request the audio focus when it becomes audible and revoke the audio focus when the controller is no longer active.

In order to have a centralized audio control in the parent process, we create two new classes here.
* MediaController
MediaController is a class used to control certain amount of media in the content process. Every controller corresponds to a browsing context.
For example, TabMediaController would correspond to the top level browsing context, which mean it can control all media in the specific tab.
* MediaControlService
As there might be multiple tabs playing audio, so there would be multiple controllers. MediaControlService is a place to manage all of them, you can access specific controller through MediaControlService by providing controller ID.
Everytime a controller becomes active, which means there is a media starts in corresponding browsing context, then controller would be added into the list of the MediaControlService. And it would be removed from the list when the media in corresponding browsering context stopped.

Another step in the renaming of VarCache variables as mirror variables,
matching the 'mirror' field used in StaticPrefList.yaml.

Converts privacy.fuzzyfox.clockgrainus varcache pref to a static pref. This pref used two #define values, which I also removed.

Ranges don't cross documents, and there's no reason the typeahead find passes a
shell around. So just don't do it.
This also fixes a bug where references to frames were kept around a flush.
That's potentially unsafe, so I've avoided the flush by passing false to
nsRange.
If something depends on it all the callers need be audited and fixed to handle a
flush properly.
Depends on D40696

Converts mozilla.widget.disable-native-theme varcache pref to a static pref and updates uses of its associated global variable with the pref. This also renames the pref to widget.disable-native-theme to group with other widget prefs.

In the event of a JSContext having gone unused between the last triggerFreeUnusedMemory() and the current one, GlobalHelperThreadState should free the temp LifoAlloc from the main thread. This isn't safe for ContextData and requires tempLifoAlloc to take a different type.
