rename "sdp" to description in a few places

Browse Source 
renames the RTCSessionDescription object from "ѕdp" to "desc" in a few places.
The term SDP should generally refer to the blob of text described in
RFC 4566 while the RTCSessionDescription specified in
  https://w3c.github.io/webrtc-pc/#rtcsessiondescription-class
contains both a type and a sdp.

BUG=None
