Subject: De-couple smbd from staticly linking against winbindd client files.

Implements a wrapper layer in winbind_util.c which are just stubs
if compiled --without-winbind.  When building with winbindd, it
is now required to build the libwbclient DSO first (in the Makefile)
and then either set LD_LIBRARY_PATH or /etc/ld.so.conf to pick up the
library PATH.
(This used to be commit 42787bccff4fcffafc7aae6a678e792604ecaaa5)
