Revert of Decoupling rtc_base from Obj-C code (patchset #8 id:140001 of https://codereview.webrtc.org/3001623003/ )

Reason for revert:
It breaks a downstream project.

Original issue's description:
> Decoupling rtc_base from Obj-C code
>
> The goal of this CL is to separate Obj-C/Obj-C++ code from targets which have
> also C++ code (see https://bugs.chromium.org/p/webrtc/issues/detail?id=7743
> for more information).
>
> To achieve this we have created 2 targets (rtc_base_objc and rtc_base_generic)
> and rtc_base will act as a proxy between these targets (this way we can avoid a
> circular dependency between rtc_base_generic and rtc_base_objc).

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.
