Applications 'should' already do this now. The problem is that the redirect is
not an official GStreamer core message so we can't really officially demand
this.
Most notably qtdemux and mmssrc will post redirects on some files that will
otherwise just fail.

These redirects are usually caused by something inside the datastream and are
thus emitted from the streaming threads. They however need to be handled from
the main thread and that makes it difficult to implement this in uridecodebin.

In this particular case, I would not find it too disgusting to embed the
rtspsrc inside sdpdemux (it already embeds the rtpbin and it's just one element
and there are no application decisions to be made about bitrates). It just
makes things more complicated wrt state changes and errors caused by the
embedded elements that it makes me avoid it.
