media-session: add media session helpers

Browse source 
Move all the media-session object monitoring into one place and
provide an API to get to the session objects.

Make API to add module specific info to objects.

Add methods to export and create objects in the session. This should
make it possible to link proxy to implementation and avoid a server
roundtrip in some cases.
