Floating-point exception observer for unit tests

This CL adds a simple tool that let a unit test fail if a floating
point exception occurs. It is possible to focus on specific exceptions.
Note that FloatingPointExceptionObserver is only effective in debug
mode. For this reason, the related unit tests only run in debug mode.
Plus, due to some platform-specific limitations, not all the floating
point exceptions are available on Android.

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.
