HEADS UPS: auto translation of T.61 strings

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

This capability has been removed.  The feature only ever
worked if all values were T.61 encoded.  This wasn't
always true with LDAPv2, and not true with LDAPv3.
Translation requires knowledge of protocol and schema,
the BER library isn't.

We'll hopefully provide the application with UTF-8 <-> T.61
conversion routines.  Converting from local charsets to
UTF-8 (or T.61) will likely be left as an exercise for
the application.

Volunteers welcomed to implement UTF-8 <-> T.61 codes
(presumely based on borrowed code).
