[PATCH] gnu: openldap: Use gnutls.

[Alex Vong]

Hello,

The following patch does what the title says. The link of the bug
<http://www.openldap.org/its/index.cgi/Incoming?id=7430;page=17> is no
longer accessible, so I assume the bug is fixd since I cannot find it on
the internet. In addition, I have checked debian's version, which is
slightly older (2.4.42), which also uses gnutls. So I think we are safe
here. Please object if there is a problem!

Please note that openldap is an input for curl, so I guess it is causing
the openssl dependency problem for octave I mentioned earlier. I haven't
test to build octave with curl though, which takes a while.

Finally, I have checked debian's build script and find the following:

======================================================================
# Download the upstream source and make changes as required for DFSG reasons.
# Assumes wget is available, as this is generally only used by the package
# maintainers.
get-orig-source:
        @if [ ! -d "debian/schema" ] ; then \
            echo 'Run this from the top directory of the Debian source' >&2; \
            exit 1; \
        fi
        wget $(URL)/openldap-$(VERSION).tgz
        tar xzf openldap-$(VERSION).tgz
        rm -r openldap-$(VERSION)/doc/drafts
        rm -r openldap-$(VERSION)/doc/rfc
        set -e; for schema in debian/schema/*.schema debian/schema/*.ldif ; do \
            file=`basename "$$schema"`; \
            rm openldap-$(VERSION)/servers/slapd/schema/$$file; \
        done
        mv openldap-$(VERSION) openldap-$(VERSION)+dfsg
        tar cf openldap_$(VERSION)+dfsg.orig.tar openldap-$(VERSION)+dfsg
        rm -r openldap-$(VERSION)+dfsg
        gzip -9 openldap_$(VERSION)+dfsg.orig.tar
======================================================================

Is the rfc documents considered fsf-free? Otherwise, we will have to
remove them and repack the source.
