1) when after processing a node there where no headers that
contained active records.
When
if (check_stale_header(node, header, &locktype, lock, &search,
&header_prev);
succeeds or
if (EXISTS(header) && !ANCIENT(header))
fails for all entries in the list leading to 'empty_node' remaining
true.
If there is are no active records we know nothing about the
current state of the name so we treat is as ISC_R_NOTFOUND.
2) when there was a covering NOQNAME proof found or all the
active headers where negative.
When
if (header->noqname != NULL &&
header->trust == dns_trust_secure)
succeeds or
if (!NEGATIVE(header))
never succeeds. Under these conditions there could (should be for
found_noqname) be a covering NSEC earlier in the tree.
