Merged requested to merge devrtz/calls:single-media-pipeline into master
While it worked so far having two different pipelines was mainly an artifact of having the pipelines modelled after two separate
gst-launch commands during initial development.
This lead to some duplication of Gstreamer elements (f.e.
rtcp_send_src, rtcp_send_sink, rtcp_recv_src, rtcp_recv_sink instead of a single pair
and is a burden when implementing SRTP due to the same sort of duplication.
