Added VP8 simulcast tests. Fixed analyzer to correctly infer timestamps.

I'm thinking we should start out without packet loss and stress that in upcoming
tests instead. WDYT?

[ilnik, 2017/02/01 15:12:50]

Done.

nit: End comments with period.

Done.

[sprang_webrtc, 2017/02/01 14:50:19]

Or even don't set this so it's unrestricted?

[ilnik, 2017/02/01 15:12:50]

Great idea. Will do that.

Please try matching the default settings for simulcast.
Normally, a 3sl case will use 1280x720, 640x360, 320x180 combo.
See webrtc/media/engine/simulcast.cc for a table of default bitrates etc.
