/*%<
* Examine the NSEC, NSEC3PARAM and privatetype RRsets at the apex of the
* database to determine which of NSEC or NSEC3 chains we are currently
* maintaining. In normal operations only one of NSEC or NSEC3 is being
* maintained but when we are transitiong between NSEC and NSEC3 we need
* to update both sets of chains. If 'privatetype' is zero then the
* privatetype RRset will not be examined.
*
* Requires:
* \li 'db' is valid.
* \li 'version' is valid or NULL.
* \li 'build_nsec' is a pointer to a isc_boolean_t or NULL.
* \li 'build_nsec3' is a pointer to a isc_boolean_t or NULL.
*
* Returns:
* \li ISC_R_SUCCESS, 'build_nsec' and 'build_nsec3' will be valid.
* \li other on error
