860f729816 Revert of Injectable Obj-C video codecs (patchset #2 id:370001 of https://codereview.webrtc.org/2979983002/ )
Reason for revert:
Still having problems with no video. Reverting.
Once no video is visible, no video is available from then on even if the callee app is in the foreground.

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.
