  Subject: [PATCH] Add export symbols related to LDAP_CONNECTIONLESS

Upstream Issue: https://bugs.openldap.org/show_bug.cgi?id=9739

But above patch is not complete, 'ber_sockbuf_io_udp' is part of an unsupported
feature (cldap or ldap over udp), only built when the unsupported
LDAP_CONNECTIONLESS flag is defined. All the user of 'ber_sockbuf_io_udp'
are included by #ifdef, so it make no sense to not include it too.
