Anders Carlsson a0349c138d Injectable Obj-C video codecs
Initial CL for this effort, with a working RTCVideoEncoder/Decoder for H264
(wrapping the VideoToolbox codec).

Some notes / things left to do:
  - There are some hard-coded references to codec types that are supported by
    webrtc::VideoCodec, cricket::VideoCodec, webrtc::CodecSpecificInfo etc
    since we need to convert to/from these types in ObjCVideoEncoder/Decoder.
    These types would need to be more codec agnostic to avoid this.
  - Most interfaces are borrowed from the design document for injectable
    codecs in Android. Some data in the corresponding C++ classes is discarded
    when converting to the Obj-C version, since it has fewer fields. I have not
    verified whether all data that we do keep is needed, or whether we might be
    losing anything useful in these conversions.
  - Implement the VideoToolbox codec code directly in the RTCVideoEncoderH264
    classes, instead of wrapping webrtc::H264VideoToolboxEncoder / decoder.
    Eliminates converting between ObjC/C++ types outside the ObjCVideoEncoder/
    Decoder wrapper classes.
  - List the injected codec factory's supported codecs in the list of codecs in
    AppRTCMobile.
