Only call the handlers if one was registered... don't require protocols to register a handler (eliminating dummies) NetConsole now uses the ARP handler when waiting on arp (instead of needing a #define hack in arp.c) Clear handlers at the end of net loop

what if the SetHandler funcs took care of setting to a dummy func when it was given NULL ? then calling code need not worry about creating their own dummies, and you don't have to add NULL pointer checking. -mike
