Bug 1432779 - P4. Remove the concept of preferred layout. r=padenot,r=kamidphish Channel layout is derived by the content being played. The concept of preferred layout is meaningless. Either we have a layout defined, or we don't. There's no in-between. So we remove it. MozReview-Commit-ID: CSCAInNmzMS
