3c6eac2860 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.

00b62b0849 Remove QualityScaler kDefaultLowQpDenominator.
This denominator doesn't make any semantic sense, it's better to use
real thresholds for when things look "good" or "bad" rather than
fractions of a max QP.

926dfcdf5e Make QualityScaler not downscale below QVGA.
Applies to all platforms, not only Android now, 160x90 video looks
awful and there's no real point to going below QVGA.

cbac40d321 Reland of Make QualityScaler more responsive to downgrades. (patchset #1 id:1 of https://codereview.webrtc.org/1880103002/ )
Reason for revert:
Regressed behavior is actually desirable (go down to 360p instead of producing super-bad 720p).

85829fd90c Make QualityScaler more responsive to downgrades.
Permits going from HD to QVGA in 6 seconds instead of 10. Also adds
windows for going up quickly in the beginning of a call (before any
downscaling happens due to bad quality).

01bcbd0df6 Make Android min-resolution rotation-agnostic.
Min resolution shouldn't have anything to do with CVO being enabled or
not, nor device rotation.

a9d0892946 Add initial bitrate and frame resolution parameters to quality scaler.
- Scale down to VGA immediately if call starts with HD resolution
and bitrate below 500 kbps.
- Adjust QP threshold for HW VP8 encoder to scale down faster.

b7ce96470b modules/video_coding/utility: Remove include
This makes it clearer this code not meant to be used as an API.
I could not find any use of this in downstream code.
