This change creates a new model which divides DASH streams into VOD, IPR, and live. It is possible to create manifests which do not fit into any of the three categories according to our model, so we now assert that our input fits cleanly into one of the three. Inline manifests used in our tests had to be updated to conform to the new model. All external test assets have been verified to fit into these categories. This is phase 1 of IPR support. There should be no behavior change in this CL. In phase 2, we will make various other parts of the library aware of IPR so that IPR-specific behaviors can be achieved.
