This is a copy of http://review.webrtc.org/864014/ This adds a FuncDurationEst to each codec instance which estimates the duration of a packet given the packet contents and the duration of the previous packet. By default, this simply returns the duration of the previous packet (which is what is currently assumed to be the duration of all future packets). This patch also provides an initial implementation of this function for G.711 which returns the actual number of samples in the packet.
