[Live-devel] Dynamically adding streams with reference counting

I hoped you looked at the code (in the "mediaServer" directory) for 
the "LIVE555 Media Server" product, because it does basically this 
(for streaming from files).

Note that it's OK to remove a "ServerMediaSession" object even while 
clients are using it.  If you do this, then the object will get 
reclaimed automatically (using reference counting) when the last 
client stops streaming from it.

Alternatively, you can do what we do for the "LIVE555 Media Server": 
Keep the "ServerMediaSession" object around, and don't actually 
remove it unless we discover later that it's no longer relevant.
