Add proxy access to some methods in Obj-C SDK

Most calls to C++ PeerConnection and related classes are proxied
to internal threads in WebRTC. However, there is no such thing
in the Obj-C SDK.
It would be nice to proxy methods in the Obj-C SDK as well.

RTCMediaStream and RTCVideoTrack have NSMutableArray members,
and it can throw NSRangeException when it has race conditions,
so that it would be a good starting point.

Also, remove some NSAsserts as its condition isn't a fatal error,
and it doesn't affect the production already.

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
