Add support for deferred sequence numbering.

With this turned on, packets will be sequence number after the pacing
stage rather that during packetization.
This avoids a race where packets may be sent out of order, and paves
the way for the ability to cull packets from the pacer queue without
causing sequence number gaps.

For now, the feature is off by default. Follow-ups will enable it for
video and audio separately.
