If you want to ask a PC what it's NetBIOS name is then you send that PC a query with the name * and then that pc sends back it's NetBIOS name

When you use Angry IP to scan all PC's on a network, Angry IP sends a NetBIOS request to each PC with the NetBIOS name as *
the file "netbiosns.c" does NOT know how to handle a * name

The Arduino NetBIOS code base for the ESP8266 has an implementation that does respond to * names. the code is here:  https://github.com/esp8266/Arduino/commit/1f7989b31d26d7df9776a08f36d685eae7ac8f99

I have taken the concepts from it and merged them into lwIP V2.0.2's "lwip\apps\netbiosns\netbiosns.c" so that it can respond to NetBIOS commands addressed to *

maybe my modifications can be merged into the lwIP next release ?

I have also changed the api "netbiosns_set_name()" to make the incoming name into upper case as per NetBIOS spec's
