 * Setup stream attributes if no stream updates are provided

 * Set up surface attributes and associate to a stream

 * The surfaces parameter is an absolute set of all surface active for the stream.

 * If no surfaces are provided, the stream will be blanked; no memory read.

 * Any flip related attribute changes must be done through this interface.

 *

 * After this call:

 *   Surfaces attributes are programmed and configured to be composed into stream.

 *   This does not trigger a flip.  No surface address is programmed.
