Added metrics test code for the FEC packet masks.
The test computes metrics (average residual loss) for each mask type and size, for a given set of loss models (random and bursty), and verifies various behaviour of the codes (including relation/comparison to RS code). http://webrtc-codereview.appspot.com/748008 TBR=stefan@webrtc.org Review URL: https://webrtc-codereview.appspot.com/929034 git-svn-id: http://webrtc.googlecode.com/svn/trunk@3189 4adac7df-926f-26a2-2b94-8c16560cd09d
