<h3>Log Message</h3>
<pre>Ensure media playback is stopped during page close
https://bugs.webkit.org/show_bug.cgi?id=146554
<rdar://problem/18033944>
Reviewed by Zalan Bujtas.
Add new method to Page class to stop all media playback. It just uses the process
MediaSessionManager singleton to inform all hosted in a particular document to stop.
* Modules/webaudio/AudioContext.h:
(WebCore::WebAudio::hostingDocument): Added.
* html/HTMLMediaElement.h:
(WebCore::HTMLMediaElement::hostingDocument): Added.
* dom/Document.cpp:
(WebCore::Document::commonTeardown): Call the new PlatformMediaSessionManager::stopAllMediaPlaybackForDocument
method on document cleanup.
* platform/audio/PlatformMediaSession.h:
Made PlatformMediaSessionManager a friend so it can access the protected 'client' accessor.
Updated PlatformMediaSessionClient to require clients to have a "hostingDocument" member.
* platform/audio/PlatformMediaSessionManager.cpp:
(WebCore::PlatformMediaSessionManager::stopAllMediaPlaybackForDocument): Added. Only pauses
playback on elements that match the provided document.
* platform/audio/PlatformMediaSessionManager.h:</pre>
