029f7cccf4 Revert of Enable trendline experiment and bayesian bitrate estimator experiment by default. (patchset #6 id:100001 of https://codereview.webrtc.org/2777333003/ )
Reason for revert:
API changes in webrtc/sdk/objc/Framework/Headers/WebRTC/RTCFieldTrials.h broke internal project

Looks like this has caused multiple Android webrtc perf build bot failures in RampUpTest.UpDownUpTransportSequenceNumberRtx

5a2c506e8e Set the start bitrate to the delay-based BWE.
This avoids issues where the bitrate produced by the codec is far lower than the target bitrate in the beginning, which causes the delay-based BWE to be initialized accordingly.

5a388368a2 Implement Theil-Sen's method for fitting a line to noisy data (used in bandwidth estimation).
Theil and Sen's estimator essentially looks at the line through every pair of points and selects the median slope. This is robust to corruption of up to 29% of the data points.

Wire up new estimator to field trial experiment. Add unit and integration tests. Results are promising.

An earlier attempt to land this was in https://codereview.webrtc.org/2518923003/

It was failed because it removed an API. This CL fixes this.

6287e82b9b Revert of Pass time constant to bwe smoothing filter. (patchset #8 id:140001 of https://codereview.webrtc.org/2518923003/ )
Reason for revert:
Unfortunately, this change breaks internal projects. Specifically the change to the CongestionController interface means anything implementing it will be forced to change in lock-step.

492ee28b73 Use bayesian estimate of acked bitrate.
This helps a lot to avoid reducing the bitrate too quickly when there's a short period of very few packets delivered, followed by the rate resuming at the regular rate. It specifically avoids the BWE going down to super low values as a response delay spikes.

280de9e1c3 Reland: Fix race / crash in OnNetworkRouteChanged().
To achieve this some refactoring was done to make it possible to synchronize
access to the DelayBasedBwe in TransportFeedbackAdapter:
- The callback was removed from DelayBasedBwe, it now instead returns its
  result.
- TransportFeedbackAdapter was moved to modules/congestion_controller to avoid
  unnecessary dependencies.

Reenables previously disabled flaky test. Can no longer reproduce flakiness with gtest-parallel and asan/tsan builds.
