[lwip-devel] HTTPD listening port: static to dynamic

[Giuseppe Modugno]

I think there are many times is useful to let the user to change the 
listening port of the embedded web server.

httpd included in lwip distribution (src/apps/httpd) uses the port 
defined by the macro HTTPD_SERVER_PORT, so it's a magic number that 
can't be changed.

I propose to change the function httpd_init() to accept one argument, 
the port number that the main application can change dynamically.

What do you think?
