Remove QualityScaler framerate reduction.

Remove QualityScaler framerate reduction.

Framerate-reduction code is disabled on all platforms, and this code
adds complexity. It's necessary to react fast, especially on mobile
platforms or other bad network conditions and framerate reduction adds
another step between HD and QVGA.

PTAL, this hasn't been active for a while and works against the goal of reacting
quickly to quickly-changing bitrates.

This is essentially a revert of https://webrtc-codereview.appspot.com/51159004,
except for the refactoring in it.

[jackychen, 2016-04-13 17:10:52]

Agree with this change based on my own observation. LGTM.

rebase

[pbos-webrtc, 2016-04-24 19:06:44]

mflodman@: Could you take a look soon, this is rebase-heavy since thresholds
etc. in QualityScaler is currently a moving target.

Code LG, I just have a question around frame dropping in general that I think is
easiest taken offline.

And if there is no intention of using the existing code again.

LGTM, please file a bug as discussed.
