- dnssec-keygen and dnssec-settime can now set key
metadata fields 0 (to unset a value, use "none")
- dnssec-revoke sets the revocation date in
addition to the revoke bit
- dnssec-settime can now print individual metadata
fields instead of always printing all of them,
and can print them in unix epoch time format for
use by scripts
