Squashed commit of the following:
commit 0d4bbd197198a94bf4e29e0ccd175a40a60097f3
Author: Gerald (Jerry) Carter <jerry at samba.org>
Date: Mon Jul 2 20:08:19 2007 -0500
Introduce GNU ld linker export-script for hiding non-public symbols
in shared libraries.
Based on initial patch from Julien Cristau <jcristau at debian.org>
and suggestions from James Peach <jpeach at samba.org>. Currently
the libsmbsharemodes libraries still exports *. Signed off on
my Derrell as well.
