Fix Description:
. adding slapi_dn_normalize_ext and its siblings to normalize/validate
   invalid DNs; deprecating slapi_dn_normalize and its siblings. (dn.c)
. replacing slapi_dn_normalize with new corresponding functions.
. normalizing hardcoded DNs (e.g., removing spaces around ',')
. setting correct DN syntax to nsslapd-suffix, nsslapd-ldapiautodnsuffix,
   costemplatedn, nsslapd-changelogsuffix, nsBaseDN, nsBindDN
