Precedence: list

This is a minor update. The changes in this version are:

- In section 4.3, attempt to clarify behaviour of the congestion circuit breaker, especially around the factor-of-ten reduction.

- In section 9, clarify behaviour regarding layered flows and bundled media within a single RTP session.
