rtspsrc: Avoid pause on other decoders of same stream after teardown.
requested to merge winand.seldeslachts/gst-plugins-good:rtspsrc-make-send-pause-configurable into master
Sending an RTSP pause message to the source of a multicast stream is not always desired behavior. If teardown is called for one the decoders of the stream, a pause request is now automatically sent. We do not necessarily want to pause the stream for other decoders.
