Reviewed by Xabier Rodriguez-Calvar.

Video frame metadata was attached only for mock sources. There's no need for a tee in the capturer
pipeline because there's never more than one client. Multiple observers watch for samples received
by the sink. And a few other drive-by and coding style cleanups.
