[Live-devel] Broken Pipe during RTP over TCP

The failure to delete the "RTSPClientSession" shouldn't cause the 
"RTSPServer" to 'become inconsistent'; it should just continue to attempt 
to stream over the (now broken) TCP connection - which will be a NOOP.

At some point in the future, the RTSPServer implementation will need to 
have a mechanism for automatically reclaiming "RTSPClientSession"s that 
have become inactive after a certain period of time - e.g., 90 seconds, 
which is what the DSS uses.  (This inactivity would be determined by the 
lack of incoming RTCP reports from the receiver.)  As a side effect, this 
will also end up closing sockets that have died.  Adding this reclamation 
mechanism isn't currently a high priority, though.
