Propagate manifest format info through to renderers.

DASH and SS manifests define potentially useful information
that isn't present in the actual media streams. Primarily
the representation id, but bitrate, fps and language may
also be defined only at the manifest leve. This change merges
the information into the sample format that's propagated to
the renderers.
