Handle WSAECONNRESET, add Telnet keepalives, rework the show_conn_table.
During long-term connection testing, I found that at least one of my
connections would have some kind of disconnect - perhaps an idle timeout,
so I have added support for sending IAC NOP packets on each net loop
timeout. Additionally, if the TCP connection does go away, we need to
detect that in the net loops and stop processing them.
Finally, since the show_conn_table was getting crowded, I put all the flags
into one column and made them smaller. This freed up enough space to show
the IP peer for the connection
