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.
