Philipp Hancke de17252e8e Reland "Unify access to SDP codec parameters"
This is a reland of commit 63d03f586b

Original change's description:
> Unify access to SDP codec parameters
>
> which come from the a=fmtp:<pt> lines in the SDP and were used as either
>   std::map<std::string, std:string>
> with three aliases,
>   cricket::CodecParameterMap
>   SdpAudioFormat::Parameters
>   SdpVideoFormat::Parameters
>
> Use webrtc::CodecParameterMap in all places.
