- the DNS_DB_NSEC3ONLY and DNS_DB_NONSEC3 flags are mutually
exclusive; it never made sense to set both at the same time.
to enforce this, it is now a fatal error to do so. the
dbiterator implementation has been cleaned up to remove
code that treated the two as independent: if nonsec3 is
true, we can be certain nsec3only is false, and vice versa.
- previously, iterating a database backwards omitted
NSEC3 records even if DNS_DB_NONSEC3 had not been set. this
has been corrected.
- when an iterator reaches the origin node of the NSEC3 tree, we
need to skip over it and go to the next node in the sequence.
the NSEC3 origin node is there for housekeeping purposes and
never contains data.
- the dbiterator_test unit test has been expanded, several
incorrect expectations have been fixed. (for example, the
expected number of iterations has been reduced by one; we were
previously counting the NSEC3 origin node and we should not
have been doing so.)
