CK_RWCOHORT_INSTANCE — declare an instance of a cohort-based reader-writer lock type

       The  user  must  use  this  macro  to  declare  instances  of lock types that they have defined using the
       CK_RWCOHORT_PROTOTYPE(3) macro.  The cohort_name must be the same as the one used in the prototype macro.
       For instance, if CK_RWCOHORT_PROTOTYPE was called with the name  "foo",  the  CK_RWCOHORT_INSTANCE  macro
       should be called as
       CK_RWCOHORT_INSTANCE(foo) cohort;

       This  macro should also be used when allocating memory for cohorts.  For instance, to allocate a block of
       4 cohorts:
       CK_RWCOHORT_WP_INSTANCE(foo) *cohorts = malloc(4 * sizeof(CK_RWCOHORT_WP_INSTANCE(foo)));
