Changes from 23/4/2014.
Changelog:
2014.04.23:
- Added a new function "RTSPServer::disableStreamingRTPOverTCP()" that you can call - on a
  RTSP server - to deny clients that request RTP/RTCP-over-TCP streaming.
- Made the constructors and destructors for the classes "RTSPServer::RTSPClientConnection"
  and "RTSPServer::RTSPClientSession" 'protected' rather than 'public', because objects of these
  classes should be created only via the "createNewClientConnection()" and
  "createNewClientSession()" virtual functions, and destroyed only by the "RTSPServer" code.
- Change the "reuse_connection" Transport parameter for our RTSP "REGISTER" command to be a
  simple flag (present, or not present), rather than a parameter that takes a value.
  (This change is also noted in the most recent update of our Internet-Draft:
  "draft-finlayson-rtsp-register-command-01.txt")
- Fixed a compilation error in "OggFileServerDemux.cpp" that occurred when DEBUG is defined.
