[lwip-users] BSD API tcp echo server port

[Andrew Lentvorski]

Folks,

I took the "unix" port, copied it to a new "unix_bsd_echoserver" port, 
stripped out everything except the tcp echo server, changed it to a 
single thread for the server (although lwip still has at least one other 
thread for the underlying stack), and converted the API to use the 
BSD-like API.

Does somebody want to take a look at this?  It ought to be somewhat 
useful to other folks trying to get the hang of the BSD-like API.

It's also quite a bit simpler than the mainline "unix" port.

If someone wants to take a look at this (and hopefully incorporate it 
into the ports tree), let me know what procedure I should follow.

Thanks,
-a

As a side note: the reason why I changed the server to a single thread 
is that I am preparing for an environment where I only get two threads. 
 My next step is to look at the underlying code and make sure it is 
only using one extra thread beyond the main server.
