Updates, cleanups and improvements over the openldap23-* ports:

 - Make sure that PKGNAMESUFFIX and COMMENT are correctly set when
   building slave ports. [1]
 - Remove RCORDER feature which is now deprecated.
 - Move PORTREVISION related stuff to before bsd.port.pre.mk in
   order to get the revisions actually work.
 - Depend on CLIENT_ONLY and WITH_SASL to determine the package
   name suffix.
 - Make use of USE_OPENLDAP instead of rolling our own.
 - Use WITH_RC_SUBR correctly rather than just specifying "yes"
 - Depend on bsd.database.mk to determine the Berkeley DB name,
   which makes it possible to use versions available from the
   ports collection rather than making decision our own. [2]
 - Disable threading as suggested by openldap developers if
   BACK_SHELL is enabled.  Indicate the fact when showing options.
 - Update to 2.3.23
