Re: [webrtc-svc] S modes and a single active simulcast layer (#73)

There are quite a few potential corner conditions: 

1. In the example, if AV1 were negotiated, then attempts to set h and f layers active will fail. 
2. Interaction of scaleResolutionDownBy with S modes.  I guess it would scale all the S mode layers down equally? 
3. Sending RIDs with S modes. Could this confuse the SFU?  The Offer would show 3 simulcast layers with distinct RIDs (and SSRCs). SFU would not see the mode (because SVC modes aren't negotiated in SDP).  So SFU could Answer and accept the 3 layers, then be surprised by receiving S mode instead.
