All you need is the socket descriptor. How to call getsockname() + 
getnameinfo() to retrieve the port number you see in libwget/net.c/
wget_tcp_get_local_port().

If MHD doesn't have such a function, either try to get the socket descriptor 
or extend MHD with a small function (similar code as in  
wget_tcp_get_local_port).
