Set profile on rtpsession as required
Submitted by Sebastian Dröge
+++ This bug was initially created as a clone of Bug 746543 +++
Currently we don't check what profile a specific client requested in SETUP, but it would be beneficial to do that and then set that specific profile on the rtpsession.
Main problem here is that we have one rtpbin for multiple clients in case of shared media, which means that every client could in theory request a different profile.
What should be done about that?
