Renaming DH_up to DH_up_ref does not warrant a CHANGES entry of its own

as the functions were only introduced a couple of days ago.

Some '*)' apparently should be '+)' as the changes do not apply
to the 0.9.6 bugfix branch.

      be done prior to destruction. Use this to unload error strings from
      ENGINEs that load their own error strings. NB: This adds two new API
      functions to "get" and "set" this destroy handler in an ENGINE.
