Reset level estimator when analog gain changes.

In AgcManagerDirect::UpdateGain(), Agc::GetRmsErrorDb() is
called. Depending on the result of that call, the analog gain may be
changed. After an analog gain change, the Agc should be reset, because
it's memory contains now invalid loudness levels.

The Agc in modules/audio_processing/agc/agc.cc resets itself at every
successful Agc::GetRmsErrorDb call. The AdaptiveModeLevelEstimatorAgc
does not. This change makes sure all Agcs are reset from
AgcManagerDirect.

It will cause some Agcs to be reset twice. This is fine, because
Agc::Reset() is cheap and idempotent.

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

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
