The usn overlay:

- Has init function usn_init instead of usn_initialize.

- Won't start, the attributes need a SYNTAX slapd knows and
  USAGE directoryOperation after NO-USER-MODIFICATION.

- Modifies sr->sr_entry in usn_operational() instead of putting
  the attribute in rs->sr_operational_attrs.  See
  back-bdb/operational.c for an example.

  Note, backend.c says
	/* NOTE: backend_operational() is also called
	 * when returning results, so it's supposed
	 * to do no harm to entries */
  which presumably means something more than just having to dup
  the entry and set MUSTBEFREED, since otherwise that comment
  applies to much more than just backend_operational().

  In fact, usn_operational() has some misindented code
			if ( !a ) {
				for ( ap = &rs->sr_operational_attrs; *ap;
					ap=&(*ap)->a_next );

					a = attr_alloc( ad_usnChanged );
					*ap = a;
				}
  which looks like it does something closer to that.

- When I tried to slapadd some entires (using Octet String
  syntax) only the first entry got an USN.

Oh well, this wasn't what I was supposed to be doing today.  I'm
just patching the overlay blindly for some other things (ITS#6758).
