Revert "IWYU: Add <cmath> for fabsf() and powf(), switch to C++ versions"

This reverts commit e90879097c7151148aaad57393967cf72d233a69.

Reason for revert: breaking downstream projects

Original change's description:
> IWYU: Add <cmath> for fabsf() and powf(), switch to C++ versions
> 
> Fix the build with libstdc++ after 496cedfe5 ("AEC3: Reverberation model:
> Changes on the decay estimation") by including the missing header:

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.
