- Part 9: EXCEPTION handlers

  The top-most stored routine blocks now support EXCEPTION clause
  in its correct place:
  AS [ declarations ]
  BEGIN statements
  [ EXCEPTION exceptions ]
  END

  Inner block will be done in a separate commit.

- Part 14: IN OUT instead of INOUT (in SP parameter declarations)
