Want "deref=" in Statslog for searches

[Hallvard B Furuseth <h.b.furuseth@usit.uio.no>]

May I add "deref=%d" to the Statslog() output for search operations in
slapd/search.c?  The format would be

  conn=%lu op=%lu SRCH base="%s" scope=%d deref=%d filter="%s"

I'd need to add yet another argument to the Statslog() macro.
Or maybe I should split it in two macros: Statslog3() with 3 arguments
and Statslog6() with 6 arguments?  Most calls only need 2-3 arguments.
