subscribe: rework some more

Browse source 
Track senders in the subscribe object and aggregate events from all
connected clients. This allows each client to get a complete view of all
the objects of pulsevideo. With all the source objects available, we can
then to the selection of the source on each client.

Remove the CreatSourceOutput on the Client1 object but let the client
select a good source and call CreateSourceOutput directly on the source.
This avoid going through the server to get a connection and the client
can just as well select a source.
Add a state property to the source and make it such that it can do async
state changes.

Remove the source provider object, each client can now directly see the
objects of another clients so there is no need for intermediate objects
in the server.
