This CL separates the files under sdk/objc into logical directories, replacing the previous file layout under Framework/. A long term goal is to have some system set up to generate the files under sdk/objc/api (the PeerConnection API wrappers) from the C++ code. In the shorter term the goal is to abstract out shared concepts from these classes in order to make them as uniform as possible. The separation into base/, components/, and helpers/ are to differentiate between the base layer's common protocols, various utilities and the actual platform specific components. The old directory layout that resembled a framework's internal layout is not necessary, since it is generated by the framework target when building it.
