Fix description: The value of newrdn was normalized as dn then
decapitalized. The decapitalization was not just needed but
the cause of the reported bug.
This patch removes the decapitalization call (slapi_dn_ignore_case)
and adds slapi_dn_ignore_case to acl_access_allowed_modrdn (acl.c)
and referint_postop_modrdn (referint/referint.c).
Additionally, unnecessary code is being removed from chaining_
back_modrdn (chainingdb/cb_modrdn.c).
