Add RtpPacketPacer interface for pacer control

Browse Source 
The PacedSender is being reworked and will need an interface so we can
inject different implementations of it.

This CL introduces a new RtpPacketPacer interface inside the pacing
module. This interface handles the details of _how_ packets should be
paced, such as pacing rates/account for audio/max queue length etc.

The RtpPacketSender interface exposed from the rtp_rtcp module handles
only the actual sending of packets.

Some minor cleanups are included here.
