Squashed commit of the following:
...
net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled.
net/tcp: TCP socket should not have to be connected to configure KeepAlive.
net/: Add a separate configuration to enable/disable KEEPALIVE socket options.
net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options.
net/tcp: Fix a backward conditional
net/tcp: Add some more checks and debug output to TCP-protocol socket options.
net/tcp: Cosmetic changes to some alignment.
net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes.

TCP Networking: When CONFIG_NET_TCP_WRITE_BUFF=y there is a situation where a NULL pointer may be dereferenced. In this configuration, the TCP connection's 'semi-permnanent' callback, s_sndcb was nullified in tcp_close_disconnect. However, other logic in tcp_lost_connection() attempt to use that callback reference after it was nullifed. Fixed in tcp_lost_connectino() by adding a NULL pointer change before the access. This was reported by Dmitriy Linikov in Bitbucket Issue 72.

Networking: Clean up some naming that has bothered me for a long time... There are no interrupts and no interrupt handlers in the network. There are events and event handler (there used to to be interrupt logic in there years ago but that is long, long gone).

Networking: A placeholder for some missing logic in the previous change related to monitoring network status for dup'ed sockets. If one of the dup'ed socket's is closed, then network monitor resources associated with that one socket must be recovered. Also, in the event that socket is being used on one thread, but then closed on another, any threads waiting for events from the socket should be informed of the closure. That latter requirement is not implemented because current data structures do not support it.

Networking: TCP disconnection callbacks are not retained in a list. This will support mutiple callbacks per lower-level TCP connection structure. That is necessary for the cae where a socket is dup'ed and shares the same lower-level connection structure. NOTE: There still needs to be a call to tcp_start_monitor() when the socket is dup'ed.
