A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/2488843003/ by guidou@chromium.org.

The reason for reverting is: Relanding since the relanding of
MediaStreamTrack.getSources (the ermoval of which is interfering with perf
tests) will have to be manual anyway..
