Subject: - adds the possibility of setting the socket receive buffer size  
 option for LLUDPServer. On windows .NET the default socket receive   buffer
 size is 8192 bytes, on recent linux systems it's about   111K. both value can
 be a bit small for an OpenSim instance serving   many clients. The socket
 receive buffer size can be configured via   an OpenSim.ini config option

- adds a general catch clause to LLUDPServer.OnReceivedData() to
  prevent it submerging when an unexpected Exception occurs.
