Propagate dns_zoneverify_dnssec() errors to callers
Since exit() is no longer called upon any dns_zoneverify_dnssec() error, verification failures should be signalled to callers. Make dns_zoneverify_dnssec() return an isc_result_t and handle both success and error appropriately in bin/dnssec/dnssec-signzone.c and bin/dnssec/dnssec-verify.c. This enables memory leak detection during shutdown of these tools and causes dnssec-signzone to print signing statistics even when zone verification fails.
