As syslog-ng 2.0 was forked earlier than tcp-keep-alive option was
added, this missing keyword was missed.

I've now committed an implementation of a so_keepalive option (renamed
for consistency), but an obsolete tcp-keep-alive() keyword was also
added for compatibility.

It should be available in tomorrow's snapshot.
