The class VideoDecoderSoftwareFallbackWrapper is an implementation detail of webrtc/media/engine/webrtcvideoengine2.cc and should not be directly under webrtc/video_decoder.h. The main purpose is to improve the dependency graph in WebRTC so that VideoDecoderSoftwareFallbackWrapper can depend on cricket::VideoCodec. The test for VideoDecoderSoftwareFallbackWrapper is also moved from webrtc/video/video_decoder_unittest.cc to webrtc/media/engine/videodecodersoftwarefallbackwrapper_unittest.cc.
