Taylor Brandstetter 3409cfa378 Start supporting H264 packetization mode 0.
The work was already done to support it, but it wasn't being negotiated
in SDP.

This means we'll now see 8 H264 payload types instead of 4; one for each
combination of BP/CBP profiles, packetization modes 0/1, and RTX/non-RTX.
This could be problematic in the future, since we're starting to run
out of dynamic payload types (using 25 of 32).
