Message:

ValidationKit/TXS: Update the TestExecService client socket used in TCP
mode to call the newly added IPRT routine RTTcpSetKeepAlive() to set
SO_KEEPALIVE along with fine-tuned keep-alive options for idle timeout
(TCP_KEEPIDLE), time interval between probes (TCP_KEEPINTVL), and the
total number of probes sent before closing the connection (TCP_KEEPCNT).
This allows the TCP connection established with the TXS client in NAT
mode to be re-established when restoring a running snapshot where TXS
had been running.
