Add connection table debugging, net byte counting, some more thread interlocks

Migrate most of the menu system into the connection structure

Clean up lots of compile warnings.
I have been getting lots of errors while testing under wine, so this
is the start of looking for problems. I have not cleaned up any
of the warnings in process_menu_line since that whole function is
an abortion and all the warnings are either send() signedness mismatch...

Start to implement a connection table
This change is only half baked as I still have not altered the rest of the
threads to use the new connection table. Nor have I updated the event
signalling model to take into account the existance of multiple connections.

Add winelib support and the ability to set the listen port

More cmdline processing fiddling

More cmdline processing hacks

Fix mode autodetection, change default tcp port back to 9600
It turns out that my telnet client doesnt work at all when I default
to port 23. Instead of debugging this problem at the moment, I am setting
the default port back to 9600

Detect if we are running as a service or console app. Change listen port to 23

Add a quit option to the menu and update help texts
