Move logic for calculating needed bitrate overhead used by NACK and FEC to VideoSender.

Browse Source 
This cl split the class MediaOptimization into two parts. One that deals with frame dropping and stats and one new class called ProtectionBitrateCalculator that deals with  calculating the needed FEC parameters and how much of the estimated network bitrate that can be used by an encoder

Note that the logic of how FEC and the needed bitrates is not changed.
