This is a reland of commit ad6807805d12e48f11c3a68b4befaf8d7c23e8b5

Original change's description:
> sdp: reject duplicate codecs with the same id but different name or clockrate
>
> since something like
>   rtpmap:96 VP8/90000
>   rtpmap:96 VP9/90000
> or
>   rtpmap:97 ISAC/32000
>   rtpmap:97 ISAC/16000
> is wrong. Note that fmtp or rtcp-fb are not taken into account.
> Also note that sending invalid static payload types now throws an error.
>
> Drive-by: replace "RtpMap" with "Rtpmap" for consistency.
>
> BUG=None

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
