gst-plugins-good: Add rtppassthroughpay element
This elements pass RTP packets along unchanged and appear as a RTP payloader element.
This is useful in the case where you are receiving RTP packets from a
different source and want to serve them over RTSP. Since the
gst-rtsp-server library expect the element marked as payX
to be a RTP
payloader element and assumes certain properties are available.
It could also be used broader, in RTP echo servers or to override the payload type.
