loadparm.c: Added new netbios aliases parameter (code from Cisco)
nameannounce.c: Code to announce aliases as well as our own names. namedbsubnet.c: Code to add the aliases to the server list. nameserv.c: Code to defend our aliases on the namelist. namework.c: Code to check it's one of our aliases. nmbd.c: Code to initialise the aliases. proto.h: Fixup protos. util.c: Code to check it's one of our aliases. All above code based on code for 1.9.16p11 donated by Cisco from Ben Woodard <bwoodard@luthien.cisco.com> Jeremy (jallison@whistle.com) (This used to be commit a2ce1c0cb1331551ff728dcfe3260fab4cd827e5)
