Instead of using two different headroom parameters, namely `kHeadroomDbfs` and `kSaturationProtectorExtraHeadroomDb`, only use the former that now also accounts for the deleted one - i.e., it equals the sum of the two headrooms. In this way, tuning AGC2 will be easier. This CL does *not* change the behavior of the AGC2 adaptive digital controller - bitexactness verified with audioproc_f on a collection of AEC dumps and Wav files (42 recordings in total). The unit tests changes in agc2/saturation_protector_unittest.cc are required since `extra_headroom_db` is removed and the changes in agc2/adaptive_digital_gain_applier_unittest.cc are required because `AdaptiveDigitalGainApplier` depends on `kHeadroomDbfs` which has been updated as stated above.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
