MXS-2013 Move or remove STR-macros

- The ones that were not used were removed.
- The ones that were used were moved close to the actual type.
  In most cases some values were missing and if the definition is
  close to the type there is a remote chance that they will stay
  in sync. If detached, they surely will not.
