Neighbor Solicitation Processing (ns_input) 

In the newest version of contiki, the function uip_nd6_ns_input() is obsolete.
ns_input function is defined static to be restrictively used in uip-nd6.c file, so removing the obsolete function requires moving the function description to the new function
