Revert "Only process cross traffic simulation if added."

This reverts commit 491d29448e4a0f501f1ea115b218ed5250fbd3dc.

Reason for revert: Breaks internal iOS waterfall

Original change's description:
> Only process cross traffic simulation if added.
> 
> This avoids extra processing overhead when there's no cross traffic
> simulation active. To allow the use of SendTask, GlobalTimeController
> is adjusted so it always overrides yield behavior.
> 
> Also adding sequence checkers to protect against races on
> read access.

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.
