Stop port 2226 getting port 2223 traffic.
Remove socket as an option for logging.
Make all debug output go to the debug socket set in addition to whereever else it is meant to go.

Remove the socket option from the debug code -- didn't work and isn't required anymore with port 2226.
Make the default action for the extra sockets to be filter everything and allow nothing through.
Make the supression of debug message to a socket set depend on each socket set individually.
Rework the default suppress callback on nil code.
Start relocating the extra sockets into example applications.

The debug socket will always exist and is created by rinApp.
The unidirectional socket is moved and has a simple filter function.
The bidirection socket is unmoved but no longer takes the 2222 stream messages.
Move port 2224 over to an example application.

Make it respond to one message in a trivial manner.
Allow our own unidirection message through the filter function and provide an example of a message edit.
