charcnv.c: Fixed silly bugs detected on IRIX.

client.c:	Fixed silly bugs detected on IRIX.
namedbname.c:	Stopped 1d names from being registered in WINS db.
namedbsubnet.c:	Only register 1e names on broadcast subnet.
nameelect.c:	Changed add_my_name entries. Forced host announces if we
                have less than 10 servers listed. Fixed registering 1b
                domain name issues.
namepacket.c:	Added error message when dgram discarded.
nameserv.c:	Added notion of 'direct' names that are not registered on
                the network. Needed to get around bugs in earlier nmbd
                handling of DOMAIN(1b) names.
nameservreply.c:Tidied up debug message.
nameservresp.c:	Added response_name_query_domain() code. Deals with
                re-registering DOMAIN(1b) name.
nmbd.c:		Fixed silly bugs detected on IRIX.
nmblib.c:	Added paranoia debugs.
proto.h:	Updated remove_name_entry(), add_my_name_entry().
server.c:	Fixed silly bugs detected on IRIX.
trans2.c:	Fixed silly bugs detected on IRIX.
uid.c:		Fixed silly bugs detected on IRIX.
version.h:	Updated to alpha3.
