Now have a better solution to the need to have smblcient find
a WINS server if running on the WINS server.  As suggested by
Andrew, we have a flag, in_client=False by default, and set it
to True in the client.  loadparam.c checks this and sets
szWINSserver to 127.0.0.1 when in_client && bWINSsupport.

BTW, we seem to have picked up and unused value in some of
Luke's new code.
