Revert 203427 "Hook up the device selection to the WebAudio live..."

Possibly caused content_browsertests to fail on Mac.

> Hook up the device selection to the WebAudio live audio.
> WebAudio live audio needs to pass the session_id to the browser process so that Chrome can open the correct input device for unitfied IO.
> 
> This CL looks big because it touches quite some interfaces from the render to the browser. But the change is simple and basically adding a session_id/device_id to the classes. All the changes some together and it is very hard to break it down.
> It also makes the media output code more similar to the media input code as well, and it will be easier to merge them for the future.
> 
> 
> BUG=147327
> TEST=http://chromium.googlecode.com/svn/trunk/samples/audio/visualizer-live.html
> Change the device using the camera icon on the right of the omnibox, then reload. Verify the sound is coming from the correct input device.
