When receiving H.264 RTP packets, we support any of these modes (i.e., we handle whatever is sent to us).

When sending H.264 RTP packets (e.g., from a server), we do so using either Single NALU packet mode, or Fragmentation Unit mode (using FU-A).  (When sending, we currently don't ever aggregate more than one NALU into a single RTP packet (although we can receive such packets OK).)
