[lwip-users] Compile warnings in socket.c

[Bill Florac]

No big deal but when I compile sockets.c I get a handful (15) of "comparison 
between signed and unsigned" warnings. These are all when comparing a type 
"socklen_t" to a sizeof().  Since I think socklen_t is universally an int, I 
suppose these all should be cast to an int? (or just disable the warning...)
 
I also get a unused parameter "len" in event_callback()
