This interface has a couple of issues. Primarily for me, it makes it difficult work with the paced sender as we need to either temporarily release a lock or force a thread-handover in order to avoid a cyclic lock order. For video in particular, its behavior is also falky since header sizes can vary not only form frame to frame, but from packet to packet within a frame (e.g. TimingInfo extension is only on the last packet, if set). On bitrate allocation, the last reported value is picked, leading to timing issues affecting the bitrate set. This CL removes the callback interface and instead we simply poll the RTP module for a packet overhead. This consists of an expected overhead based on which non-volatile header extensions are registered (so for instance AbsoluteCaptureTime is disregarded since it's only populated once per second). The overhead estimation is a little less accurate but instead simpler and deterministic.
