Prepare control support

We will have arrays of controls passed to tldap.c. Follow a mantra from the
classic book "Thinking Forth" by Leo Brodie: Favor counts over terminators :-)

This makes the parameter lists to tldap pretty long, but everyone will have
wrapper routines anyway, see for example tldap_search_fmt. And the OpenLDAP
manpages call the non-_ext routines deprecated, probably for a reason.
