fix edge detection with ice

Set an ICE check list to the Failed state if the corresponding media stream has been deactivated by the peer.

 - Move the ICE session from the Sal Op to the LinphoneCall.
 - Do not access directly to the ICE session to generate the SDP from
   the media description or to generate the media description from the
   SDP. Instead include ICE attributes in the media description.
