[relp] RELP Windows Port

[chris mr]

Rainer, 
I was just looking into RFC3195 when I found the RELP rsyslog implementation.  I think this is an excellent move forward with system logging.  This is a much simpler implementation than RFC3195; well done!
I see that you are relying on the client to re-transmit the message if client-server transaction fails.  You also mention the server issuing commands (hints) to the client and I think that is a great idea.  The server should be able to re-request the message from the client, as well as the client should receive acknowledgment that the server processed the message successfully.  Receipt acknowledgment of the message at the transport layer is not enough.  I think a successful logging protocol should extend itself all the way until the last byte of the message is written to storage and verified.
I particularly like the relp_software field which will help with application specific message parsing.
Am I reading this correctly that a successful transaction will be a minimum of eleven packets or can the offers part be bypassed?
