Message:

IPRT: tcp.h+tcp.cpp,socket.h+socket.cpp: Add RTTcpSetKeepAlive() which
allows one to enable or disable sending periodic keep-alive messages on
a socket (SO_KEEPALIVE) as described in RFC 1122. RTTcpSetKeepAlive()
also allows one to adjust several keep-alive options on a per-socket
basis: the idle time before keep-alive probes are sent (TCP_KEEPIDLE
(TCP_KEEPALIVE on macOS)), the amount of time between keep-alive probes
(TCP_KEEPINTVL), and the number of keep-alive probes to send before
closing the connection (TCP_KEEPCNT).
